Installing the adapterFollow the instructions included with your adapter. The adapterinstalls into a single slot.

To connect the cable to the adapter:

1. (Optical cable only) Remove the protective covers on eachfiber-optic cable.

2. Plug one end of the cable into the connector on the adapter asshown in the appropriate figure in this step. (The hardware mightbe rotated 90 degrees clockwise from the orientation shown.)

• Fibre Channel adapter connectivity options include coppercable with DB9 connector, SC optical, and LC optical cable, asshown next.

– SFP+ (Twinax cable)

3. Plug the other end of the cable into a connector on the storagesystem or a hub/switch port.

4. Label each cable to identify the adapter and thestorage/switch/hub port to which it connects.

5. After connecting all adapters in the server, power up the server.

Matching the adapter with the correct PCI slotWhen choosing an adapter for your server, it is important to knowwhich adapter is compatible with your server’s PCI/PCI-X/PCIExpress slots. Certain adapter models have specific voltagerequirements or physical limitations that allow them to only work inspecific slots.

Installing the adapter 15

16


Servers today have several different bus slot types for acceptingadapters. PCI, PCI-X, PCI-X 2.0, and PCI-Express.

PCI slots can be 32-bit and 64-bit (denoted by their 124-pin or 188-pinconnectors). These slots have plastic “keys” that prevent certainadapters from fitting into them. These keys work with the cutoutnotches in the adapter edge connector so that only compatibleadapters will fit into them. This is done because of the voltagecharacteristics of the adapter. Inserting a 3.3v adapter into a 5v slotwould cause severe damage to both the adapter and the server.Therefore, the slot keys denote the type of voltage provided by theslot and effectively prevent a voltage incompatible adapter frombeing inserted.

Figure 2 shows how PCI slots will appear with their keys and whattype of voltage is provided for each slot type.

Figure 2 PCI slot types and voltage key locations

Figure 3 on page 17 shows the adapter edge connectors compatiblewith the PCI slots shown in Figure 1 on page 13. Note adapter #5which shows a universal adapter edge connector. Universal adaptersare compatible with both 3.3v and 5v PCI slots.



Figure 3 Adapter edge connectors

PCI-X (or PCI Extended) slots increase the speed that data travelsover the bus. PCI-X slots appear identical to a 64-Bit PCI slot keyedfor 3.3v. (Refer to number 3 in Figure 2 on page 16 and Figure 3.)PCI-X slots are backwards compatible with 3.3v PCI adapters anduniversal adapters. Inserting standard PCI adapters into PCI-X slotswill lower the bus speed, however, as they cannot take advantage ofthe improved performance.

PCI-X 2.0 is the next generation of PCI-X buses. PCI-X 2.0 increasesthe bus speed providing more performance for adapters. PCI-X 2.0slots also appear identical to a 64-bit PCI slot keyed for 3.3v. (Refer tonumber 3 in Figure 2 and Figure 3.) PCI-X 2.0 is also fullybackward-compatible with 3.3v PCI and PCI-X.

PCI Express (sometimes noted as PCIe) is a new bus type that usesthe existing PCI model, but implements it in a faster, serial protocol.Because of the serial way it transmits data, the PCI Express bus slotcan be different sizes depending on the throughput it supports. PCIExpress slot speeds are expressed in "lanes" and are normally shownas x1, x4, x8, and x16. Each type of slot are different lengths (Figure 4on page 18) and adapter edge connectors will also have varyinglengths depending on how many lanes they require for throughput.Because of how PCI Express slots are keyed, an x1 adapter can beinserted in all 4 slot types as the adapter will negotiate with the slot todetermine the highest mutually supported number of lanes.


18


However, an adapter requiring x16 lanes will not fit into a smallerslot.

Figure 4 PCI Express slots

Figure 5 shows x1, x4, and x16 lane slots aligned on a mainboard. Youcan see how the slots are keyed so that low-lane adapters can fit intolarger slots.

Figure 5 PCI Express slots aligned



Brocade offers adapters for each bus/slot type available. Table 1shows each of the EMC-supported Brocade adapters, and theirrespective slot requirements. Be sure to consult both your server userguide and Brocade to insure that the adapter you want to use iscompatible with your server’s bus.

a. Gen1 (PCI Base Specification 1.0, 1.01a, 1.1), effective data rate is 16 Gb/s.

b. Gen2 (PCI Express Base Specification 2.0), effective data rate is 32 Gb/s.

Always refer to the latest EMC Support Matrix for the most up-to-dateinformation on servers that support these adapters.

Booting from the external storage arrayBrocade’s software release 2.2 supports booting the system from adevice on an external storage array. This boot device is a Logical UnitNumber (LUN) located on the external storage array. The adapterboot code loads from Brocade adapter memory into system memoryand integrates with the host system (server) BIOS during system bootto facilitate booting from array-based LUNs.

The Brocade adapter boot code supports the following host platformenvironments:

◆ PCI BIOS2.1 and above, PCI firmware 3.0

Boot code for PCI system

◆ BIOS

Boot code for x86 and x64 platforms

◆ Unified Extensible Firmware Interface (UEFI)

Boot code for UEFI systems

This section provides the following information:

◆ “Verifying boot BIOS code installation,” next

◆ “Installing/updating the Brocade adapter boot BIOS using theLiveCD” on page 21

◆ “Configuring the Brocade adapter boot BIOS settings using theBIOS configuration menu” on page 24

Verifying boot BIOS code installationThe Brocade adapter may not have the boot BIOS code installed. Thiscan be verified by looking for a Brocade Banner, which displaysduring Power-On Self Test (POST) when the system is booted.

◆ If the banner is displayed, a boot BIOS image corresponding tothe version shown in the banner is already installed on theBrocade adapter. Verify that the Brocade BIOS version displayedduring POST corresponds with the most recent version listed inthe EMC Support Matrix.





◆ If the Brocade adapter BIOS version does not correspond with theversion listed in the EMC Support Matrix, or if no Brocade adapterbanner is displayed during Power-On Self Test (POST) when thesystem is booted, then the latest EMC-supported Brocade bootBIOS image must be installed to the adapter.

◆ If updating the boot BIOS code on a system without an existingoperating system, the boot BIOS code update is most easilyaccomplished by using the latest LiveCD ISO image from theEMC-supported section of the Brocade website at


The LiveCD ISO image contains the adapter driver, boot code, andminimal operating system to allow you to install the boot BIOS codeto the Brocade adapter.

If updating the boot BIOS on a system that is already installed with aWindows operating system, refer to the “Brocade advanced utilities”on page 81.

Installing/updating the Brocade adapter boot BIOS using the LiveCDTo install or update the Brocade adapter boot BIOS using the LiveCD,complete the following steps.

1. Obtain the latest LiveCD ISO image from the EMC-supportedsection of the Brocade website at


2. Create a CD from this image.

3. Install the CD into the CD/DVD ROM drive and boot the system,ensuring that the system is set to boot from the CD/DVD ROMdrive first.

Table 2 Options available (page 2 of 2)

Field Description



A screen similar to the following is displayed.

A list of four boot ID entries is displayed, showing the Port WWNand the LUN number of the device which is configured for boot.Up to four boot device entries can be configured.

The first device (ID 0) listed is the primary boot device. The hostfirst attempts to boot from this device, then the succeedingdevices in the list.

Note: If configuring multiple boot entries with VNX™ series andCLARiiON® storage systems, your HBA(s) must be registered inFailover Mode 4 (ALUA). VNX series supports ALUA.

6. Use the Up and Down arrow keys to select a boot device entry,and one of the following options to configure the boot deviceentry:

• C — Clear an existing boot device from the selected Boot IDentry

• M — Edit boot device information by manually entering thePort WWN and LUN number for the array-based boot device.


30


• <Enter> — Edit boot device information by selectingautomatically detected array port WWNs and LUN numberswhich have been made visible to the adapter port WWN.

Note: This option requires that the Brocade adapter port WWN hasalready been zoned to the appropriate array target port, and thatLUN masking has been configured on the array, such that a LUN isvisible to the adapter port WWN.

If configuring using automatically detected array port WWNsand LUNs by clicking Enter, a screen similar to the followingappears, which displays automatically detected array portWWNs.

Note: If the Brocade adapter port WWN has not been properly zoned tothe appropriate array port WWN, then the utility will display "No targetdevices found or link down!" Ensure that the adapter port beingconfigured for boot has been properly zoned to the appropriate arrayport WWN from which the adapter will boot.

7. Select the array port WWN target to be designated from which toboot and press Enter.



A screen similar to the following displays device information ofthe available LUNs which can be specified as the boot device.

IMPORTANT

The above example shows a Symmetrix array target which hasboth a 2 MB VCM pseudo device available, as well as a 16 GBvolume. While shown as an option, the 2 MB volume is not avalid device from which to boot, and any attempt to use thisdevice during OS install will fail.

Note: Ensure that a proper device is selected with enough space for theOS to be installed (in this instance, the second available entry, which isthe 16 GB LUN. If a suitable LUN is not shown in the list, ensure that theappropriate LUN masking has been configured on the array, such that asuitable boot LUN is visible to the adapter port WWN.

Select the appropriate LUN on the array target to be designated as theboot device and press Enter to return to the screen, as shown in Step 5,where the boot ID entry selected previously now reports the configuredarray port WWN target and LUN number.

To configure additional boot ID entries (for example, to provide multiplepaths to the LUN ID through different array port WWN targets), return

to Step 6, select the next boot ID entry, and configuring similarly.

8. When the appropriate array port WWN target and LUN IDs havebeen configured for all required adapter ports, press Alt-S to savethe configuration and then select Exit Brocade Config menu toexit the BIOS Configuration Utility.

At this point, the system will reboot with the configuredarray-based LUN as its boot device.

Note: In the above example screenshot, the Adapter x/y "Brocade's BIOSnot installed" output does not indicate a problem since those adapterports were not configured for BIOS boot; only the first adapter port isconfigured for boot. The "Brocade's BIOS installed successfully" indicatesthat the system will boot from the configured array LUN.



Fabric-based boot LUN discoveryFabric-based boot LUN discovery is a Brocade standards-basedapproach to managing and simplifying SAN boot complexity toimprove reliability while ensuring that best practices are employed toautomate dynamic virtual server configurations. An example isshown in Figure 6.

Brocade HBA's fabric-based boot LUN discovery eliminates themanual process of boot LUN configurations of each HBA from eachserver console. This capability improves configuration reliability,containing operational costs and making the adoption of disklessservers a practical alternative for even large data centers.

Figure 6 Fabric-based boot LUN discovery example

Fabric-based boot LUN discovery 33

This feature allows the host's boot LUN information to be stored inthe fabric zone database using a zone name containing the PWWN ofan adapter port and zone members consisting of the storage targetPWWN and LUN WWN. The adapter boot code can query the zonemember list for the zone name that matches the adapter PWWN todetermine the boot target and LUN.

To store the information, you must use the Fabric OS zoneCreatecommand to create a zone on the switch where the adapter isconnected.

Note: Fabric OS 6.2 and above is required on adjacent switches to supportfabric-based boot LUN discovery.

This feature is not supported on UEFI systems.

Configuring fabric-based boot LUN discoveryComplete the following steps to configure fabric-based boot LUNdiscovery.

1. Set the adapter's BIOS configuration to auto discovery using oneof the following interfaces:

• Brocade BIOS Configuration Utility, as shown in Figure 7:

Figure 7 Auto Discovery – BIOS



• HCM (Basic Port Configuration > Boot-over-SAN > AutoDiscovered from Fabric), as shown in Figure 8:

Figure 8 Auto Discovery – HCM

• BCU (C:\bios -enable <port_id> -o auto), as shown inFigure 9:

Figure 9 Auto Discovery – BCU

2. Enter the following BCU command to provide the zone name andzone members to use as operands in the Fabric OS zonecreatecommand.

bcu boot -blunZone -c <cfg> -p <port_wwn> -r <rport_wwn> -l <lun_id | lun#>


36


where:

For example, enter the following on the Centralized Boot LUNmanagement Server:

The command output will contain the proper encoding and be inthe exact format for the FOS OS ZoneCreate command:

cfg Specifies boot LUN (BLUN).

port_wwn The hexadecimal WWN of the adapterport connecting to the boot LUN. Forexample, 10:00:00:05:1e:0c:1e:a8 which wewill be using in this document.

rport_wwn The hexadecimal WWN of the remotestorage target's port. For example,50:06:04:84:52:a7:53:97 which we will beusing in this document.

lun_id | lun# The hexadecimal LUN identification. Youcan provide this as a hexadecimalone-Byte value or an eight-Byte value(four-level addressing). For example aneight-Byte value could be0034AABBCCDDEEFF, or a one-Bye valuecould be "01".



3. Configure the zone on the switch using the Fabric OS zoneCreatecommand. Use the display output from the bfaZoneCreatecommand as the zonename and member operands:

Zonecreate "zonename", "member[; member...]"

For example:

zonecreate "BFA_100000051E0C1EA8_BLUN", "00:00:00:00:50:06:04:84;00:00:00:01:52:a7:53:97; 00:00:00:02:00:34:00:00; 00:00:00:03:00:00:00:00"

4. .Enter the FOS OS cfgSave command on the switch to save thezone configuration.

Note: The zone created is only an entity to store boot LUN data. There isno zone enforcement by the fabric. Therefore, you must create a separatezone containing the adapter port and storage target port to ensure thatthe adapter port is able to see the target.

5. When you power on the system, you will see the Brocade BIOSinstalling the Boot BIOS successfully if the above configurationsare correct, as shown in Figure 10.

Windows 2003 internal or external boot disk installationThis section is a step-by-step procedure for installing Windows 2003operating system to either an internal or external boot device.

After you have your adapter(s) installed in your server, andconfigured for external boot if necessary, the next step is to install theWindows operating system. If you intend to boot to an externaldevice please refer to “Booting from the external storage array” onpage 20 for setting the boot BIOS for external boot and selecting theexternal boot lun. Refer to your server’s documentation for preparingyour server for external boot.

Note: If you intend to boot to an external disk, only present the LUN that youintend to boot from. All additional luns can be added after the installation.This will eliminate any confusion on selecting the correct partition forinstallation and eliminates any problems that the Operating System coencounter on reboot during the installation. Also confirm there is only onepath to the storage array. Having more than one path can cause the operatingsystem to fail during the installation.

You need the following materials to install Windows:

◆ A Windows CD-ROM for the Windows version you want toinstall

◆ AN EMC-approved adapter driver diskette for Windows

To install Windows 2003 operating system to either an internal orexternal boot device, complete the following steps.

1. Insert a bootable Windows CD-ROM in the drive and reboot thesystem

• If your system has a bootable disk already configured from aprevious installation, the software will prompt you to pressany key to boot from CD-ROM.



• If you are booting from your server's internal hard disk, youmay skip to Step 5 on page 42 when the Windows Setupscreen displays.

• If you are installing Windows to boot from an external arraydisk, you will need to supply setup with the adapter driver. Todo this, immediately after the Windows installation begins,press F6 when directed or when the blue screen appears.Otherwise, proceed to Step 5.

– Pressing F6 tells the Windows installer you want to load athird-party driver before proceeding with the installation.

– If you do not press F6 in time to add the drivers, restart theserver and try again. You will know if you missed the F6function to install third-party drivers when the setupreturns with a warning that it cannot find a partition toload the operating system.

Windows 2008 Server Core operating system optionWindows Server 2008 includes a variation of an installation called aServer Core. Server Core is a "scaled-back" installation where noWindows Explorer shell is installed. All configuration andmaintenance is done either through the command line interfacewindows or by connecting to the machine remotely using MicrosoftManagement Console.

Figure 27 Server Core installation example

Limitations Since Server Core is a special installation of Windows Server 2008, thefollowing limitations exist:

◆ You cannot upgrade from a previous version of the WindowsServer operating system to a Server Core installation. Only aclean installation is supported.



◆ You cannot upgrade from a full installation of Windows Server2008 to a Server Core installation. Only a clean installation issupported.

◆ You cannot upgrade from a Server Core installation to a fullinstallation of Windows Server 2008. If you need the Windowsuser interface or a server role that is not supported in a ServerCore installation, you must install a full installation of WindowsServer 2008.

EMC support EMC supports the use of Server Core for attach to EMC storagearrays. The currently supported adapter drivers/firmware/BIOS andadapter driver utilities are approved for use with this version ofWindows 2008. Use of the Brocade driver install wizard (executabledriver package), as shown in Figure 28, works exactly as it will on astandard Windows 2008 installation, but the wizard must be startedfrom the command prompt.

Fibre Channel over Ethernet (FCoE)EMC supports Brocade Fibre Channel over Ethernet (FCoE)Converged Network Adapter (CNA). FCoE adapters represent amethod to converge both Fibre Channel and Ethernet traffic over asingle physical link to a switch infrastructure that manages bothstorage (SAN) and network (IP) connectivity within a single unit.

The benefits of FCoE technology become apparent in large datacenters:

◆ Where dense, rack-mounted and blade server chassis exist.

◆ Where physical cable topology simplification is a priority.

◆ In virtualization environments, where several physical storageand network links are commonly required.

The installation of the Brocade FCoE CNA provides the host with a 10Gb Ethernet interface and a Brocade Fibre Channel adapter interface.

Upon installation of the proper driver for the FCoE CNA, the FibreChannel interface will function identically to that of a standardBrocade Fibre Channel HBA. The FCoE CNA simply encapsulatesFibre Channel traffic within Ethernet frames. As such, FC-basedcontent within this guide also applies directly to Brocade FCoECNAs.

In-depth information about FCoE and its supported features andtopologies can be found in the "Fibre Channel over Ethernet (FCoE)"chapter of the EMC Networked Storage Topology Guide, availablethrough E-Lab Interoperability Navigator at:http://elabnavigator.EMC.com.

For CNA configuration procedures, refer to “Fibre Channel overEthernet (FCoE) Converged Network Adapter (CNA) procedures” onpage 70.

Fibre Channel over Ethernet (FCoE) Converged NetworkAdapter (CNA) procedures

FCoE CNAs are similar to Fibre Channel adapters in that they requiredrivers in order to function in a Windows server. However, becauseof its ability to converge both Fibre Channel and Ethernet traffic overa single physical link, the adapter will appear to the Windows serveras two different pieces of hardware. When viewing the WindowsDevice Manager, you will see both a Brocade 10 Gigabit Ethernetadapter as well as a a Brocade Fibre Channel adapter (10G FCoEHBA) available in the system, as shown in Figure 43.

Miscellaneous Planning and Procedures

Zoning and connection planning in a fabric environmentIn a fabric environment, the user should plan for the switch topology,target-to-hosts mapping, and the zone. Here is an overview of therecommended procedure:

1. Draw the connectivity among the hosts, switch, and storage arrayto verify the correct fabric configuration.

2. Configure the zone capability in the switch. If connecting to EMCConnectrix™, refer to the Connectrix v7.01 Enterprise StorageNetwork System Planning Guide for information on the zoneconfiguration.



Boot-from-SAN configuration restrictionsRefer to the EMC Support Matrix for any specific boot-from-SANrestrictions. This guide no longer contains restriction information,and the information in the EMC Support Matrix supersedes anyrestriction references found in previous adapter installation guides.

Further information on booting Microsoft Windows from externalstorage can be found in the EMC Host Connectivity Guide for Windows.

Benefits of booting from the storage arrayBenefits of storage-based booting include:

◆ Faster replacement/addition of server capacity, enabled byseparation of the boot image from the server.

◆ Lower investment in internal server-based RAID cards withlimited capability.

◆ Leveraged investment in the storage network through the highavailability, data integrity, and storage management of anexternal RAID storage system.

◆ Leveraged commodity high-density server technology andcentralized storage offered by diskless servers usingSAN-attached storage systems.

Booting from the EMC storage array works effectively with certainSAN-based environments, including multiserver redundantapplications, Web farms, and terminal server applications where ann+1 server environment protects customers against different types offailures.

Some applications may not be optimized for storage array-basedbooting. EMC strongly recommends customers fully investigate theirapplication and data availability requirements and consult with anEMC account team to determine the configuration that best meetstheir needs.

Operating system/driver capabilities and limitationsThe following capabilities and limitations should be noted forWindows operating systems with Brocade adapters.

◆ “LUNs,” discussed next

◆ “Volume sizes” on page 87

LUNsTheoretically, Windows supports up to 261,120 total LUNs. Thisfigure is based on the listed support limitations for Windows Serverfrom Microsoft: 8 buses per adapter, 128 targets per bus, and 255LUNs per target. However, due to registry hive limitations, aWindows server is most likely to run out of registry space to keeptrack of these large LUN counts well before reaching this limit.Windows 2000 has this registry size issue. See Microsoftknowledge-base articles 292726 and 269075 for information.Windows 2003 does not have this issue.

Microsoft Windows limits the number of LUNs per adapter to 255(LUNs 00-FE) even though the adapters are capable of presenting 256(LUNs 00-FF). It is a function of the operating system that preventsthat last LUN from being presented to the user, and not the adapter ordriver. This limitation should be taken into consideration whenplanning your host configuration.

Based on E-Lab testing, it has been determined that for EMCconfigurations, Windows servers should be limited to a maximum of500 LUNs. In most cases, this number will be more than sufficient. Inothers, it may be deemed too small. For configurations where a largeamount of storage is necessary, but not necessarily a large number ofdisks, EMC storage can be configured to present LUNs of large sizesto the host


Troubleshooting

Volume sizesWindows 2003 and Windows 2008 support a maximum file systemsize of 2 TB unless Service Pack 1 or later is installed. With SP1 orlater, the maximum supported physical disk size is 256 TB.

Note: Volumes larger than 2 TB must use GPT partitions to support them.Refer to your Windows users guide for information on GPT partitions.

Note: Windows for x64 servers does not require SP1 or later to create GPTpartitions.

EMC storage arrays provide the ability to expand the size of a LUNpresented to the host server. Refer to your EMC array'sdocumentation for procedures on expanding LUN sizes. Windowshas the ability to recognize the extra space on these expanded LUNsby performing a rescan via the Disk Administrator window.

Troubleshooting

Understanding persistent bindingPersistent binding is the mechanism to create a continuous logicalroute from a storage device object in the Windows host to a volume inthe EMC storage array across the fabric.

Without a persistent binding mechanism, the host cannot maintainpersistent logical routing of the communication from a storage deviceobject across the fabric to an EMC storage array volume. If thephysical configuration of the switch is changed (for example, thecable is swapped or the host is rebooted), the logical route becomesinconsistent, causing possible data corruption if the user applicationis modifying data through inconsistent logical routing of thecommunication from the driver entry point to a volume in an EMCstorage array across the fabric.

The Windows operating system (OS) does not provide a satisfactorymeans to allow persistent binding. Most software applications accessstorage using file systems managed by the Windows OS. (Filesystems are represented as <drive letters> <colons>, that is, C:, D:,and so forth.) For storage devices containing file systems, Windowswrites a disk signature to the disk device. The operating system canthen identify and associate with, a particular drive letter and filesystem.

Since the signature resides on the disk device, changes can occur onthe storage end (a cable swap, for example) that can cause a diskdevice to be visible to the host server in a new location. However, theOS looks for the disk signature and, providing that nothing on thedisk changed, associate the signature with the correct drive letter andfile system. This mechanism is strictly an operating system featureand is not influenced by the Fibre Channel device driver.

Some software applications, however, do not use the Windows filesystems or drive letters for their storage requirements. Instead theyaccess storage drives directly, using their own built-in “file systems.”Devices accessed in this way are referred to as raw devices and areknown as physical drives in Windows terminology.

The naming convention for physical drives is simple and is alwaysthe same for software applications using them. A raw device underWindows is accessed by the name \\.\PHYSICALDRIVEXXX,where XXX is the drive number. For example, a system with threehard disks attached using an Brocade Fibre Channel controllerassigns the disks the names \\.\PHYSICALDRIVE0,

Understanding persistent binding 89

Troubleshooting

\\.\PHYSICALDRIVE1, and \\.\PHYSICALDRIVE2. The numberis assigned during the disk discovery part of the Windows bootprocess.

During boot-up, the Windows OS loads the driver for the storageadapters. Once loaded, the OS performs a SCSI Inquiry command toobtain information about all the attached storage devices. Each diskdrive it discovers is assigned a number in a semi-biased first come, firstserve fashion based on adapter. (Semi-biased means that the Windowssystem always begins with the controller in the lowest-numbered PCIslot where a storage controller resides. Once the driver for the storagecontroller is loaded, the OS selects the adapter in thelowest-numbered PCI slot to begin the drive discovery process.)

It is this naming convention and the process by which drives arediscovered that makes persistent binding (by definition) impossiblefor Windows. Persistent binding requires a continuous logical routefrom a storage device object in the Windows host to a volume in anEMC storage array across the fabric. As mentioned above, each diskdrive is assigned a number in a first-come, first-serve basis. This iswhere faults can occur.

Example Imagine this scenario: A host system contains controllers in slots 0, 1,and 2. Someone removes a cable from the Brocade controller in hostPCI slot 0, then reboots the host.

During reboot, the Windows OS loads the Brocade driver duringreboot and begins disk discovery. Under the scenario presentedabove, there are no devices discovered on controller 0, so the OSmoves to the controller in slot 1 and begins naming the disks it finds,starting with \\.\PHYSICALDRIVE0. Any software applicationsaccessing \\.\PHSYICALDRIVE0 before the reboot will be unableto locate their data on the device, because it changed.

The following figure shows the original configuration before thereboot. adapter 0 is in PCI slot 0 of the Windows host. Each adapterhas four disk devices connected to it, so Windows has assigned thename \\.\PHYSICALDRIVE0 to the first disk on adapter 0. Eachdisk after that is assigned a number in sequence as shown inFigure 49 on page 91.


Troubleshooting

Figure 49 Original configuration before the reboot

Figure 50 shows the same host after the cable attached to adapter0has been removed and the host rebooted. Since Windows was unableto do a discovery on adapter 0, it assigned \\.\PHYSICALDRIVE0to the first device it discovered. In this case, that first device isconnected to adapter1. Due to the shift, any software applicationaccessing \\.\PHYSICALDRIVE0 will not find data previouslywritten on the original \\.\PHYSICALDRIVE0.

Figure 50 Host after the rebooted

The default driver behavior does not store target bindings betweenhost reboots. The bindings are dynamically generated by the adapterwhen new target devices are detected.

Note: Tape devices are treated the same as disk devices in Windows withrespect to persistent binding. Refer to your tape device documentation formore information.

Troubleshooting

Understanding queue depthEach port on EMC storage arrays has a maximum queue depth. Theperformance implications in a large fabric environment with manyHBAs (initiators) generating I/Os is that a storage port's queue canquickly fill up to the maximum. When this happens, the HBA will benotified by the array with queue full (QFULL) messages and result invery poor response times. Various operating systems deal with queuefull differently.

Windows operating systems with STORPort drivers will throttle I/Osdown to a minimum in an attempt to prevent filling the queue. Whenthe queue full messages subside, STORPort will increase the queuedepth again. This could take up to around a minute in someinstances, depending on the load. The performance of the server'sapplications will be impacted, sometimes to the point of hanging orcrashing if it happens repeatedly or for a prolonged amount of time.

In order to avoid overloading the storage array's ports, you cancalculate the maximum queue depth using a combination of thenumber of initiators per storage port and the number of LUNs ESXuses. Other initiators are likely to be sharing the same SP ports, sothese will also need to have their queue depths limited. The math tocalculate the maximum queue depth is:

QD = Maximum Port Queue Length / (Initiators * LUNs)

For example, there are 4 servers with single HBA ports connected to asingle port on the storage array, with 5 LUNs masked to each server.The storage port's maximum queue length is 1600 outstandingcommands. This leads to the following queue depth calculation:

HBA Queue Depth = 1600 / (4 * 20)

In this example, the calculated HBA queue depth would be 20. Acertain amount of over-subscription can be tolerated because allLUNs assigned to the servers are unlikely to be busy at the sametime, especially if additional HBA ports and load balancing softwareis used. So in the example above, a queue depth of 32 should notcause queue full. However, a queue depth value of 256 or highercould cause performance issues.


Troubleshooting

Using this example, it is easy to extrapolate the potential performanceimplications of large server environments with large numbers ofservers and initiators. This includes virtualized environments likeHyper-V that use synthetic/virtual Fibre Channel adapters and NPIVenvironments, where there are a number of virtual initiatorsconnecting through the same physical HBA port.

Problems and solutionsThis section contains known problems and solutions.

Problem 1 Error Message ID: 51 — In the event viewer when attempting toinstall multiple host access (for clustering) to the same EMC VNXseries and CLARiiON system storage group. The text of the messagereads:

An Error was detected on device \Device\Harddisk<x>\DR<x>during a paging operation

Solution Until host cluster software is installed, only a single host shouldaccess a storage group at a time. Refer to the EMC Support Matrix forsupported host configurations.

Problem 2 EMC Knowledge base solution emc29097 — If using adaptersconnected to both VNX series and CLARiiON SPs, withoutPowerPath installed, duplicate LUNs will be visible in the DeviceManager and Disk Manager. Only one instance of the LUN will beaccessible, and all other matching mappings will be listed asUnknown, Unreadable, and Unallocated.

Solution This is normal behavior when multiple paths are available,PowerPath is not installed, and the initiator type is registered inPowerPath mode (array default depending on core code revision).
