Antivirus enhancementsThis ONTAP release includes new features and enhancements related to Antivirus.
Support for Vscan on-demand scanning
Beginning with ONTAP 9, Vscan supports on-demand scanning.
With on-demand scanning, you can create an on-demand task to scan all files under one or moredirectories, including files in subdirectories. Scanning can be scheduled to run immediately or at alater time, for example, during off-peak hours. Important parameters of the completed on-demandtask are recorded in the rdb table and in the report file.
Support for FQDN configuration of Vscan servers
Beginning with ONTAP 9, Vscan supports Fully Qualified Domain Name (FQDN) configuration ofVscan servers using the vserver vscan scanner pool command.
The -servers option of the vserver vscan scanner pool command has been deprecated. Youcan now use the -hostnames option to supply the IP address or host name of the Vscan server forFQDN configuration.
API updatesThis ONTAP release provides information about managing ONTAP systems using APIs.
Support for REST APIs
ONTAP 9.6 extends the REST API support originally introduced in ONTAP 9.4 for the applicationaware data management feature. The ONTAP REST API now supports most ONTAP configurationand administration tasks.
REST APIs in ONTAP 9.6 include the following key areas and many more:
• Cluster Setup
• Protocol configuration
24
• Provisioning
• Performance monitoring
• Data protection
• Application aware data management
The ONTAP 9 REST API Developers Guide includes everything you need to get started with theAPIs, include sample code and an overview of the available APIs.
An API reference is built into ONTAP 9.6. Point a web browser to the cluster management address ofyour ONTAP cluster to view detailed information and examples for all of the available REST APIs:

API support for ONTAP 9 automation
You can manage ONTAP systems by using APIs. The NetApp Manageability SDK provides APIs fordeveloping applications that monitor and manage storage systems. OnCommand WorkflowAutomation (OnCommand WFA) enables you to run prepackaged workflows that automatemanagement tasks using APIs.
The SDK supports C, C++, Java, Perl, C#, VB.NET, PowerShell, Python, and Ruby as the scriptinglanguage on the client side. You can download the SDK from the NetApp Support Site.
You can also use APIs to automate management tasks without writing scripts. OnCommandWorkflow Automation provides several prepackaged workflows that automate management taskssuch as the workflows that are described in Express Guides. You can download the OnCommandWFA pack from the NetApp Storage Automation Store.
For information about the versions of the NetApp Manageability SDK and OnCommand WorkflowAutomation that are supported with your version of ONTAP, see the Interoperability Matrix Tool.

Application Aware Data Management and Balanced Placement
ONTAP 9.2 introduces application aware data management workflow for both AFF and FASplatforms.
Application aware data management simplifies storage setup and enables you to serve data inminutes for key applications by providing inputs relevant to the application. Storage is configuredand provisioned to both application vendor and NetApp best practices, helping preventmisconfigurations that can lead to performance issues.
Application aware data management also uses balanced placement to help optimally provisionapplications, providing automatic placement of storage objects based on the desired performanceservice levels and available system resources. This allows you to understand if desired performance isor is not available at the time of provisioning the applications.
Once applications are provisioned, you can gain insight and control with the ability to view andmanage storage resources at an application granularity.
The application data management workflow can be accessed from ONTAP System Manager underthe Applications tab. Support is provided for common applications including general SAN and NAS,server virtualization (SAN and NFS), and Oracle single instance and RAC (SAN and NAS).

Support for cluster setup
Beginning with System Manager 9.1, you can use System Manager to set up a new cluster byconfiguring the node management IP address on any node, and then by adding other nodes.
Using the Cluster Setup feature, you can add licences; set up node management, cluster management,and Service Processor management networks; configure the DNS and NTP servers; set upAutoSupport messages and event notifications; create backup information for single-node clusters;and create SVMs using the recommended storage settings.
You can set up the cluster by using a template file or by manually entering the values in the guidedsetup.
Cluster management using System Manager
Support for most active files or clients functionality
You can track and report the most active instances of a file or client in a cluster using statisticalsampling techniques. This information is available through a command line or System Manager.
In an enterprise data center where ONTAP systems are deployed and accessed with multipleprotocols (NFS, CIFS, FC, iSCSI) by multiple clients simultaneously, it is possible that a particularfile might receive a disproportionally large amount of traffic. Similarly, a particular client might begenerating disproportionally large amount of traffic. This can cause severe performance degradationon a cluster. The most active files or clients functionality tracks and reports the most active instanceof file or client in the cluster, enabling you to narrow in on a high traffic file or client to resolve theissue quickly.
The most active files or clients functionality is a standard ONTAP component and does not requireany setup or installation.
FIPS 140-2 support for cluster-wide control plane web service interfaces
Beginning with ONTAP 9, you can enable the Federal Information Processing Standard (FIPS) 140-2compliance mode for cluster-wide control plane web service interfaces.
By default, the FIPS 140-2 only mode is disabled. You can enable the FIPS 140-2 compliance modeby setting the is-fips-enabled parameter to true for the security config modifycommand, and then use the security config show command to confirm the online status.
When the FIPS 140-2 compliance is enabled, TLSv1 and SSLv3 are disabled, and only TLSv1.1 andTLSv1.2 remain enabled. ONTAP prevents you from enabling TLSv1 and SSLv3 when the FIPS140-2 compliance mode is enabled.
If you enable FIPS 140-2 mode and then subsequently disable it, TLSv1 and SSLv3 remain disabled,but TLSv1.2 or both TLSv1.1 and TLSv1.2 remain enabled depending on the previous configuration.

Changes in audit configuration operation
A storage administrator can create an audit configuration for a storage virtual machine (SVM) byusing the vserver audit create command. If the audit destination path has volumes hosted onan unmirrored aggregate on the MetroCluster configuration node, ONTAP displays a messagewarning that the specified path does not have MetroCluster synchronous disaster recovery protection.
Support for SHA-2 password hash function
To enhance password security, ONTAP 9 and later releases support the SHA-2 password hashfunction and use SHA-512 by default for hashing newly created or changed passwords. You can alsoexpire or lock accounts as needed.
Existing user accounts with unchanged passwords continue to use the MD5 hash function after theupgrade to ONTAP 9 or later, and users can continue to access their accounts. However, it is stronglyrecommended that you migrate MD5 accounts to SHA-512 by having users change their passwords.
The password hash functionality enables you to do the following:
• Display user accounts that match the specified hash function.
• Expire accounts that use a specified hash function (for example, MD5), forcing the users tochange their passwords in their next login.
• Lock accounts whose passwords use the specified hash function.
• When reverting to a release earlier than ONTAP 9, reset the cluster administrator’s own passwordfor it to be compatible with the hash function (MD5) that is supported by the earlier release.
ONTAP accepts pre-hashed SHA-2 passwords only by using NetApp Manageability SDK (security-login-create and security-login-modify-password).

Changes in EMS configuration operation
You must configure important EMS event notifications to be sent either as email, forwarded to asyslog server, or forwarded to an SNMP traphost. Beginning with ONTAP 9, the commands havechanged.
If the AutoSupport noteto parameter is configured with email addresses, they are automaticallycopied into EMS notification destinations when upgrading to ONTAP 9 or 9.1. A new EMSnotification is also created that maps the important-events filter to these addresses. As a result,you will start receiving two email notifications for each callhome event until you remove the emailaddresses from the AutoSupport noteto parameter. You will also start receiving email notificationsabout other important events that are originally configured.

SAN enhancementsThis ONTAP release includes new features and enhancements for SAN.
New and changed features in the ONTAP 9 release family | 55
Volume mobility now supported for NVMe
Beginning in ONTAP 9.6, limited volume mobility is supported for the NVMe protocol.
Volumes containing NVMe namespaces can be moved from a node to its HA partner or another nodein the cluster. Volumes containing NVMe namespaces cannot be moved within the same node.
An NVMe LIF must exist on the destination node prior to the volume move.
LUN resizing limitation removed in ONTAP 9.5
Beginning with ONTAP 9.5, a LUN can be resized up to 16 TB, which is the maximum size allowed,regardless of the LUN's initial size.
This limitation applies to LUNs created in any version of ONTAP 9, except LUNs with the Solarisosytpe. Solaris LUNs cannot be resized.
The ONTAP 9 SAN Administration Guide indicates that you can only grow your LUN up to 10 timesthe original size. This applies only to ONTAP 9.4 and earlier.
Support for NVMe protocol
ONTAP 9.4 introduces NVMe over Fibre Channel (NVMe/FC), a new block access protocol thatserves blocks to the host in a similar manner to FCP and iSCSI.
NVMe/FC uses an NVMe command set instead of SCSI. The NVMe architecture, lean command set,and scalable sessions enable significant reduction in latency and increase in parallelism, making itwell suited to low-latency and high-throughput applications such as in-memory databases, analytics,and more.
You can provision and configure NVMe/FC through on-box OnCommand System Manager enteringthe IP address of the cluster management or any of the node management ports or by using thecommand line interface (CLI). End-to-end NVMe/FC connectivity from the host through SAN Fabricto NetApp AFF controllers is necessary to get the maximum performance using this new protocol.Consult the NetApp Interoperability Matrix Tool to verify the latest supported solution stack forONTAP 9.4.
Note: ONTAP 9.4 implementation of NVMe/FC requires application-level high availability. In theevent of a controller loss or path failure, the application host needs to manage path failover to itshigh availability (HA) partner. This limitation exists because the NVMe multipathing specificationcalled Asymmetric Namespace Access (ANA), analogous to ALUA in the SCSI protocol, was stillunder development. While implementing NVMe/FC, NetApp has helped design the ANA protocolat the NVMe forum, where it was recently ratified.
Support for iSCSI Endpoint Isolation
In ONTAP 9.2 existing iSCSI security commands where enhanced to now accept an IP address range,or multiple IP addresses. This new functionality prevents an initiator from logging into the cluster ifthe origination IP address is unsupported or unknown, providing a more unique identificationscheme.
Add an IP address range, or multiple IP addresses with the vserver iscsi security add-initiator-address-range command.
cluster1::> vserver iscsi security add-initiator-address-range
Refer to the SAN administration guide for more information on iSCSI initiator security management.

Support for simplified SAN AFF provisioning templates
Beginning with ONTAP 9.1, a new SAN provisioning template based on NetApp best practices isavailable in the ONTAP System Manager.
Using the storage provisioning templates can prevent misconfigurations that lead to performanceissues.
The following template is accessible under the Application Provisioning tab:
• SAN SAP HANA
Support for increasing the maximum SAN cluster size to 12 nodes
Beginning with ONTAP 9.1, the number of nodes you can add to a SAN cluster has increased from 8to 12. Support for 12-node SAN clusters has the same limits as those used for 8-node clusters; that is,the per-node and per-cluster object count limits are the same as for 8-node SAN.
The user cannot disable Selective LUN Map (SLM) when the cluster has more than 8 nodes. If SLMis disabled, you cannot add the ninth node to the cluster until SLM is turned on again.

Gigabit Ethernet connectivity link speed is autoconfigured for FAS2552 andFAS2554 systems
For FAS2552 and FAS2554 systems with Converged Network Adapter (CNA) ports, also known asUnified Target Adapters 2 (UTA 2) ports, the Gigabit Ethernet (GbE) connectivity link speed isautoconfigured. The speed at which the interface operates (1 or 10 GbE) depends on the type ofmodule that is inserted. If a 10 GbE module is inserted, the interface operates at 10 GbE. Similarly, ifa 1 GbE module is inserted, the interface operates at 1 GbE.
Note:
• FCoE is not supported when the interface is operating at 1GbE speed.
• The terms converged network adapter and unified target adapter are synonyms. Depending onthe model and how it is configured, the adapter can provide Fibre Channel, iSCSI, or FCoE/Ethernet capability.
New and changed features in the ONTAP 9 release family | 57
ODX LUN copy is now supported between clusters
Beginning with ONTAP 9, you can use Microsoft Offloaded Data Transfer (ODX, also known ascopy offload) for intercluster LUN transfers in SAN environments, in addition to inter-volume andinter-SVM transfers that were previously supported.
Intercluster ODX is supported for SAN protocols only, not for SMB.

iSCSI target support for an FQDN response
Beginning with ONTAP 9, clusters can be configured to return a fully qualified domain name(FQDN) response when a host OS sends an iSCSI discovery request. An FQDN response isconfigured with the iSCSI interface modify command at the advanced privilege level.
The return of an FQDN response is useful when there is a Network Address Translation (NAT)device between the host OS and the storage service. IP addresses on one side of the NAT device areinvalid on the other side, but FQDNs can be valid on both sides.

• Interactive data reporting enabled by default
• Support for manually enabling inactive data reporting on HDD aggregates
• Volume move without cloud tier data copy
• Enhancements in ONTAP System Manager to the Volume Performance tab of the Volume 360page to show cloud latency of the volume
The key enhancements for FabricPool in ONTAP 9.5 include the following:
60 | Release Notes
• Support for specifying the aggregate fullness thresholdYou can modify the aggregate fullness threshold used by the tiering scan by using the storageaggregate object-store modify command with the -tiering-fullness-thresholdparameter in the advanced privilege level to adjust the aggregate utilization percentage reachedbefore FabricPool starts tiering. The default value is 50 percent.
• Support for using IBM Cloud Object Storage as the cloud tier for FabricPool
• Support for AWS Commercial Cloud Services (C2S)
• Support for attaching aggregates that contain qualified FlexGroup volume constituentsYou can use the allow-flexgroup true option with the storage aggregate object-store attach command to attach aggregates that contain FlexGroup volume constituents.
• NetApp Volume Encryption (NVE) of the cloud tierIf the source volume is NVE enabled, this feature is enabled by default, and the encryption ispreserved across the cloud tier.
The key enhancements for FabricPool in ONTAP 9.4 include the following:
• Support for the auto tiering policyThe auto tiering policy moves cold user data in both the Snapshot copies and the active filesystem to the capacity tier after the tiering minimum cooling period (31 days by default).
• Support for modifying the tiering minimum cooling periodYou can change the tiering minimum cooling period on a volume that uses the snapshot-onlyor auto tiering policy.
• Support for Microsoft Azure Blob Storage for the cloud as the external capacity tier
• Inactive data reportingInactive data reporting enables you to see how much data in a volume is inactive, regardless ofwhether the aggregate is part of FabricPool. You need to explicitly enable the inactive datareporting functionality if the aggregate is not used for FabricPool.
• Support for ONTAP SelectOnly all flash (all SSD) aggregates are supported for using FabricPool with ONTAP Select.
• Support for object defragmentationFabricPool now defragments objects based on the percentage of used blocks in the object. Thisenhancement reclaims space used by blocks that have been deleted or are no longer beingreferenced by the performance tier. The default percentage for the threshold depends on the objectstore's provider type. You can specify the threshold percentage.

Support for storage tiers by using FabricPool
Beginning with ONTAP 9.2, you can enhance the efficiency and balance the performance and cost ofyour storage system by using FabricPool as a storage tiering solution. You can use the CLI orONTAP System Manager for this functionality.
FabricPool uses an all flash (all SSD) aggregate as the performance tier to store data that is “hot”(frequently accessed). It uses an object store as the external capacity tier to store data that is “cold”(infrequently accessed). Tiering policy options are available at the volume level to provide flexibilityand efficiency in moving data across tiers as data becomes hot or cold.
ONTAP supports using Amazon Web Services Simple Storage Service (AWS S3) and NetAppStorageGRID as the capacity tier for FabricPool. Newly ordered AFF systems come with 10 TB offree capacity for using AWS S3 with FabricPool. If you need additional capacity for AWS S3 on an
New and changed features in the ONTAP 9 release family | 61
AFF system, if you use AWS S3 as the capacity tier with a non-AFF system, or if you upgrade froman existing cluster, you need a FabricPool license. A license is not required if you use NetAppStorageGRID as the capacity tier.
The following functionality or features are not currently supported with FabricPool:
• Information lifecycle management (ILM) policies that are applied to object store buckets
• 7-Mode data transition using the ONTAP CLI commands or the 7-Mode Transition Tool
• FlexArray Virtualization

Upgrade enhancementsThis ONTAP release includes new features and enhancements related to the software upgradeprocess.
Support for direct ONTAP software image upload
Beginning in ONTAP 9.4, you can copy the ONTAP software image from the NetApp Support Site toa local folder. You do not have to copy the software image to an HTTP or FTP server.
Support for automated non-disruptive upgrade for MetroClusterconfigurations
Beginning with ONTAP 9.4, automated non-disruptive upgrade from ONTAP 9.3 to ONTAP 9.4 issupported for MetroCluster configurations through the command line interface (CLI).
Enhancements for cluster join and unjoin
Beginning with ONTAP 9.3, changes have been made to the cluster join functionality to enhancecluster stability and to the cluster unjoin functionality for mixed version clusters to enhance ease ofuse.
Beginning with ONTAP 9.3, all nodes in a cluster must be running the same version of ONTAPbefore a new node can be joined. By default, you cannot join new nodes of a different version. Thisincrease cluster stability. If necessary for an upgrade, you can override the default behavior and join anode of a different version using the following advance privilege commands:
• cluster join -allow-mixed-version-join
• cluster add-node -allow-mixed-version-join
In such cases, you should complete the upgrade as quickly as possible; do not allow the cluster toremain in a mixed version state longer than necessary.
Also beginning with ONTAP 9.3, in the case of a mixed version cluster, you can now unjoin the lastlow version node from the cluster using the advance privilege cluster unjoin -skip-last-low-version-node-check command.
Support for additional upgrade, downgrade, and revert paths
With each ONTAP release, new paths are available for upgrade to the last ONTAP version. Paths todowngrade or revert from the latest version are also available.

Requirements for running ONTAP 9
You must ensure that you have the required storage systems and firmware to run the ONTAPsoftware for the ONTAP 9 release family.
Supported systems and cluster configurationsTo ensure that your systems and cluster configurations are supported to run ONTAP 9, you shouldcheck your configuration on the Hardware Universe before upgrading clustered nodes or beforeadding new nodes to an existing cluster.
The maximum number of nodes that are supported per cluster depends on the hardware platformmodel and whether NAS or SAN protocols are running.
A cluster can be homogenous (all nodes have the same platform model) or mixed (nodes havedifferent platform models); mixed clusters are supported with some restrictions. The maximumnumber of nodes within a cluster is determined by the platform that supports the fewest number ofnodes. Clusters must consist of high-availability (HA) pairs, and the nodes within an HA pair musthave the same platform model.
To know about the ONTAP systems that use array LUNs and supported ONTAP 9.x releases, see theHardware Universe.
Note: If your system sends AutoSupport records to NetApp, you should use the Upgrade Advisortool to plan your upgrade. Upgrade Advisor can also help you to determine whether your systemsand cluster configurations are supported to run ONTAP 9. For more information, see the UpgradeAdvisor help screens.

Requirement for upgrading ONTAP 9.5 or later with NetApp VolumeEncryption
If you are upgrading a system with NetApp Volume Encryption to ONTAP 9.5 or later, you must usethe ONTAP software image for non-restricted countries to perform the upgrade.
If you use the ONTAP software image for restricted countries to upgrade a system with NetAppVolume Encryption, the system panics and you lose access to your volumes.
SSH connections fail after upgrade to ONTAP 9.3 if HMAC algorithms notremoved prior to upgrade
Beginning in ONTAP 9.3, HMAC algorithms are not supported. If, prior to upgrading to ONTAP 9.3,your storage virtual machines (SVMs) are configured with HMAC algorithms, after upgrading toONTAP 9.3, SSH connections fail.
You can use the following command to determine if you have SVMs configured with the HMACalgorithm: security ssh show mac-algorithms hmac-ripemd160* -vserver *-fieldsvserver
If you have SVMs configured with the HMAC algorithm, you can use the ssh remove command toremove the algorithm before the upgrade.
Fast path routes disabled after upgrade to ONTAP 9.2 and later
As part of general networking stack enhancements, fast path routing configurations are disabled afterupgrading to ONTAP 9.2 and later. If you use fast path routing, you should plan to verify that routingis correctly configured by checking Active IQ system risks before upgrading.
In earlier releases, fast path routing configurations made it difficult to identify problems withimproper routing tables. Fast path routing has been replaced by route caching, which acceleratesrouting lookups.

An additional reboot might be required after upgrading to ONTAP 9.2 orlater
If Data Encryption Standard (DES) or Triple Data Encryption Standard (3DES) is enabled when youupgrade to ONTAP 9.2 or later, an additional reboot might be required after the reboot required forthe upgrade.
When the upgrade is complete, the output of the security config status show commandindicates if an additional reboot is needed.
Note: The command output only states if a reboot is required. It does not reference DES or 3DESas the reason for the reboot.
To avoid this issue, disable DES and 3DES before upgrading.
Data transfers might be queued on lower memory platforms after upgradeto ONTAP 9.2
In ONTAP 9.2 or later, the number of source systems that can simultaneously transfer data to adestination system is based on a percentage of system memory. This can cause some data transfers tobe queued on platforms with low system memory.
Contact technical support for assistance if you encounter this issue.

Upgrade to ONTAP 9.2 fails on systems with unicode directories greaterthan 2MB in root volume
If you have unicode directories that are 2MB or greater in the root volume, an upgrade from ONTAP9.1 on ONTAP 9.2 might fail. This issue is fixed in ONTAP 9.2P3 and later. If you are upgrading to aversion of ONTAP 9.2P2 or earlier, you must perform steps prior to the upgrade to reduce the size ofthe unicode directories and prevent the failure.
Steps
1. On the root volume, verify that the create_ucode or the convert_ucode option is activated:
volume show volume_name -fields create-ucode,convert-ucode
2. From the Freebsd system shell, verify that there are directories greater than 2MB:
find /mroot -type d -size +2M

Change in audit logging after upgrade
Beginning in ONTAP 9, the command-history.log file is replaced by the audit.log file, and themgwd.log file no longer contains audit information. Before upgrading, you should review any scriptsor tools that refer to the previous files and their contents.
Although new command-history.log files are no longer created, existing command-history.log files are preserved after upgrade to ONTAP 9. They are rotated out (deleted) as newaudit.log files are rotated in (created).
Tools and scripts that check the command-history.log file might continue to work because a softlink from the command-history.log file to the audit.log file is created during the upgrade.However, tools and scripts that check the mgwd.log file will fail because that file no longer containsaudit information.
In addition, audit logs in ONTAP 9 and later releases no longer include the following entries, whichare not considered useful and cause unnecessary logging activity:
• Internal commands run by ONTAP (that is, where username=root)
• Command aliases (separately from the command they point to)

Revert requirements for FabricPool
You need to be aware of a few revert requirements related to FabricPool.
• The following revert requirements apply if you have a FabricPool or object store configuration inthe cluster and you want to revert to a release earlier than ONTAP 9.2:
◦ You must first move volumes in any existing FabricPool-enabled aggregate to anotheraggregate prior to the revert.
◦ You must remove any associated object store configuration from the cluster.
• The following revert requirements apply if you use Azure Blob Storage as the object store for theFabricPool cloud tier and you want to revert to a release earlier than 9.4:
◦ You must first move volumes from the aggregate that is attached to Azure Blob Storage toanother aggregate.
◦ You must remove the object store configuration that is associated with Azure Blob Storagefrom the cluster.
• The following revert requirements apply if you use ONTAP Select with FabricPool and you wantto revert to a release earlier than ONTAP 9.4:
◦ You must first move volumes in any existing FabricPool-enabled aggregate to anotheraggregate.
◦ You must remove any associated object store configuration from ONTAP Select.
• If you have a volume that uses the auto tiering policy and you want to revert to ONTAP 9.3 orONTAP 9.2, you must first change the tiering policy from auto to another tiering policy(snapshot-only, backup, or none).
• The following revert requirements apply if you use IBM Cloud Object Storage as the object storefor the FabricPool cloud tier and you want to revert to a release earlier than 9.5:
◦ You must first move volumes from the aggregate that is attached to IBM Cloud Object Storageto another aggregate.
◦ You must remove the object store configuration that is associated with IBM Cloud ObjectStorage from the cluster.
• The following revert requirements apply if a FlexGroup resides on FabricPool aggregates and youwant to revert to a release earlier than ONTAP 9.5:
◦ You must first move all the constituents from FabricPool aggregates to non-FabricPoolaggregates using the vol move command with the -allow-mixed-aggr-types option.
◦ You must ensure that existing non-FabricPool aggregates have enough space to host theFlexGroup you are moving from FabricPool, or that there are enough spare disks available tocreate new non-FabricPool aggregates to host the FlexGroup you are moving.
• If you are using NetApp Volume Encryption (NVE) enabled volumes with FabricPools and youwant to revert to a release earlier than ONTAP 9.5, you must do one of the following:
78 | Release Notes
◦ Convert the volume to plaintext (unencrypted)
◦ Move the volume to a non-FabricPool aggregate
Downgrade or revert not supported for SnapLock volumes
You cannot downgrade or revert aggregates containing SnapLock volumes to an ONTAP versionprior to ONTAP 9.1.
Requirement to revert password hash function to a release before ONTAP 9
Before reverting to a release earlier than ONTAP 9, you must run the advanced command securitylogin password-prepare-to-downgrade with the -disable-feature-setdowngrade_version option from the console by using a user account with the cluster admin role.If you do not run this command, the revert process fails. After the revert, users must change theirpasswords.
If your password is not encrypted with a hash function supported by the release you are reverting to,the command prompts you for a new password and encrypts it with the supported hash function. Thepasswords for all other users are marked expired. After the revert, you must temporarily change thepasswords for all users, and users are prompted to change their passwords again upon login through aconsole or SSH session.

Unexpected application impacts after resizing application volumes andLUNs
In ONTAP 9.2 and earlier, when an application is initially provisioned, a Quality of Service (QoS)policy is created for each application volume. If an application volume or LUN within the applicationvolume is resized, the QoS policy is not automatically updated and the application might experienceunexpected impacts.
ONTAP does not prevent the resizing of application volumes or application LUNs, but to avoidunexpected impacts, call support before attempting to resize application volumes or applicationLUNs.
Beginning with ONTAP 9.3, the QoS policy is automatically updated so that manual adjustment ofthe QoS policy associated with any resized application LUNs is not necessary.
SP and BMC remote management devices on multiple FAS and AFFsystems can be affected by high network load
On several FAS and AFF systems, a high network load in the management network might cause theService Processor (SP) or Baseboard Management Controller (BMC) to become unresponsive. If thishappens, the device cannot report environmental conditions correctly, which could cause the systemto shut down.
The following systems are potentially affected by this issue:
• AFF A700, AFF A300, AFF A220, AFF A200, and AFF8000 series
• FAS9000, FAS8200 and FAS8000 series
• FAS2700, FAS2600 and FAS2500 series
The high network load might be due to excessive ingress broadcast traffic, multicast traffic, or insome cases unicast denial-of-service (DoS) attacks.
To avoid this problem, you should ensure that you are running the latest firmware for the SP or BMC,and you should avoid putting the wrench port in a network with excessive ingress broadcast ormulticast traffic loads.

ONTAP 9.5 must allow pre-shared key (PSK) cipher suites for cluster peering to work. PSK ciphersuites (and most other secure suites) are enabled by default. However, if you need to restrict thecipher suites using the security config modify command with the -supported-cipheroption, you must allow cipher suites based on PSKs as well as AES-GCM suites. If you do not usethe default or explicitly include PSK suites, cluster peering will fail.
To explicitly include PSK suites, be sure to include the value "PSK-AES256-GCM-SHA384" inaddition to any other required values with the -supported-cipher option.

Converting 40GbE NIC ports into multiple 10GbE ports for 10GbEconnectivity
The X1144A-R6 and the X91440A-R6 40GbE Network Interface Cards (NICs) can be converted tosupport four 10GbE ports. If you are connecting a hardware platform that supports one of these NICsto a cluster that supports 10GbE cluster interconnect and customer data connections, the NIC must beconverted to provide the necessary 10GbE connections.
Before you begin
You must be using a supported breakout cable.
About this task
For a complete list of platforms that support NICs, see the Hardware Universe.
Hardware Universe
Note: On the X1144A-R6 NIC, only port A can be converted to support the four 10GbEconnections. Once port A is converted, port e is not available for use.
86 | Release Notes
Steps
1. Enter maintenance mode.
2. Convert the NIC from 40GbE support to 10GbE support.
nicadmin convert –m [40G | 10G] [port-name]
3. Reboot the system.
New limits for IPspaces
Beginning with ONTAP 9, there is a cluster-wide limit of 512 IPspaces. The cluster-wide limit isreduced to 256 IPspaces for clusters that have platforms with 6 GB of RAM or less, such as FAS2220or FAS2240. See the Hardware Universe to determine whether additional limits apply to yourplatform.

Cluster performance data values in System Manager are higher than inREST API output
The cluster performance data that ONTAP System Manager 9.6 displays is different than the valuesreturned by REST API/api/cluster/metrics.
In System Manager, the cluster dashboard uses the workload_queue_nblade:node object to reportperformance data. The workload_queue_nblade:node object includes system and diagnostic workloadstatistics as well as user workloads; therefore, the data displays differently than the REST APIoutput.

SAN administration issuesYou should review the known issues and limitations with features related to SAN protocols andadministration.
Storage LUNs/paths not accessible by the host with Cisco Nexus 5000/6000running NX-OS versions 7.1(3)N1(1) to 7.1(3)N1(4)
A SAN host might not see its LUN after the target port goes down and then comes back up again.The port shows as up on both host and target. The host might also show a LUN, but the target port isdown and the LUN is not accessible.
This issue is caused by the Nexus 5000/6000 Switches not sending the RSCN message to connecteddevices when a member in the same zone disconnects or connects when there is a zoning change.
You can check whether or not a Nexus Switch has sent RSCN messages by running the followingswitch command:

Storage SLC and size of second redo log component is applied to bothmirrored redo log components of Oracle RAC applications
There is a limitation with how the storage service level class (SLC) and size values are applied inapplications for Oracle Real Application Clusters (RAC) that have redo log mirroring enabled if theOracle application is created in ONTAP 9.2 and modified in ONTAP 9.4 or later.
Applications for Oracle RAC that have redo log mirroring enabled and that are created in ONTAP 9.2have two redo log application components.
When you modify the storage SLC for the second application-component using ONTAP SystemManager in ONTAP 9.4, the value gets applied to both redo log components.
When you modify the SLC or the size of the second application-component using ONTAP SystemManager in ONTAP 9.5, the value gets applied to both redo log components.
In ONTAP 9.4 and later, the value specified for the first redo log application-component with such anapplication is ignored during the modify operation, and the value specified for the second redo logapplication-component is applied to both.
This behavior is seen only in Oracle application that is created in ONTAP 9.2 and modified inONTAP 9.4 or later. Starting with ONTAP 9.3, only one redo log component is created even whenredo log mirroring is enabled.
