8 Preface

1 Installation

You and your HP service representative each play a role in installation. Your HP service representativeis responsible for installing the disk array and formatting the disk devices. You are responsible forconfiguring the host server for the new devices with assistance from your HP service representative.

Features and requirementsAsk your HP service representative about the latest supported hardware and software.

The disk array has the following features:

• Storage capacity: The capacity for each model is listed below:XP10000: Up to 240 drives for up to 69.2 TB, 48 FC portsXP12000: Up to 1152 drives for up to 332 TB, 128 FC portsSVS200: Up to 127 TB of external storage, 48 FC ports

• Server support: IBM RS/6000 series, POWERstation, POWERserver, or SP series• Operating system support: IBM AIX OS with current OS patches

Before installing the disk array, ensure the following requirements are met:

• Superuser access: Make sure you have superuser (root) access• Host Bus Adapters (HBAs): Install HBAs and all utilities and drivers. Refer to the adapter

documentation for installation details• (Recommended) HP StorageWorks Remote Web Console XP, Command View XP Advanced

Edition or Command View XP with LUN management feature for configuring disk array portsand paths

• (Recommended) HP StorageWorks LUN Configuration and Security Manager XP• (Optional) Other available XP software (some may not be supported by your system):

HP StorageWorks Business Copy XPHP StorageWorks Continuous Access XPHP StorageWorks Continuous Access Extension XPHP StorageWorks Continuous Access XP JournalHP StorageWorks Auto LUN XPHP StorageWorks Data Exchange XPHP StorageWorks RAID Manager XPHP StorageWorks Cache LUN XPHP StorageWorks Auto Path XPHP StorageWorks Cluster Extension XPHP StorageWorks Performance Advisor XP SoftwareHP StorageWorks External Storage XPHP StorageWorks XP Disk/Cache Partition SoftwareHP StorageWorks Flex Copy XPHP StorageWorks XP Data Shredder SoftwareHP StorageWorks Performance Control XP


Fibre Channel interfaceThe XP family of disk arrays and the SVS200 support these Fibre Channel elements:

• Connection speeds of 1 Gbps, 2 Gbps, and 4 Gbps (XP12000/XP10000 only)• Short-wave non-OFC (open fiber control) optical interface• Multimode optical cables with SC or LC connectors• Public or private arbitrated loop (FC-AL) or direct fabric attach• Fibre Channel switches

Even though the interface is Fibre Channel, this guide uses the term “SCSI disk” because disk arraydevices are defined to the host as SCSI disks.

Device emulation typesThe XP family of disk arrays and the SVS200 support these device emulation types:

• OPEN-x devices: OPEN-x logical units represent disk devices. Except for OPEN-V, these devicesare based on fixed sizes. OPEN-V is a user-defined size. Supported emulations include OPEN-3,OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.

• LUSE devices (OPEN-x*n): Logical Unit Size Expansion (LUSE) devices combine 2 to 36 OPEN-xdevices to create expanded LDEVs larger than standard OPEN-x disk devices. For example, anOPEN-x LUSE volume created from ten OPEN-x volumes is designated as OPEN-x*10.

• CVS devices (OPEN-x CVS): Volume Size Configuration (VSC) defines custom volumes (CVS) thatare smaller than normal fixed-sized logical disk devices (volumes). (OPEN-V is a CVS-basedcustom disk size that you determine. OPEN-L does not support CVS.)

• LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSE CVS combines CVS devices to create anexpanded device. This is done by first creating CVS custom-sized devices and then using LUSE tocombine from 2 to 36 CVS devices. For example, if three OPEN-9 CVS volumes are combined tocreate an expanded device, this device is designated as OPEN-9*3-CVS.

NOTE:For the SVS200, and the XP12000/XP10000 when connected to external storage devices, HPrecommends using OPEN-V as the emulation the array makes visible to the host. This allows externalstorage LDEVs to be configured without losing data. Using any other emulation may cause data lossin the external storage LUNs.

FailoverThe disk arrays support many standard software products that provide host, application, or I/O pathfailover and management.

10 Installation

SNMP configurationThe XP family of disk arrays and the SVS200 support standard Simple Network Management Protocol(SNMP) for remotely managing arrays. The SNMP agent on the service processor (SVP) performserror-reporting operations requested by the SNMP manager. SNMP properties are usually set from theSVP but they can also be set remotely using Remote Web Console, Command View (XP arrays only), orCommand View XP Advanced Edition. Refer to the applicable user’s guide for procedures.

RAID Manager command devicesRAID Manager manages Business Copy (BC) or Continuous Access (CA) operations from a host server.To use RAID Manager you must designate at least one LDEV as a command device. This can be donewith Remote Web Console, Command View (XP arrays only), or Command View XP Advanced Edition to. Refer to the applicable user guide for information about how to designate a command device.


Installation proceduresPerform these actions to install and configure the disk array:

1. Install and configure the disk array

• Setting the host mode and host group mode• Setting the System Option Modes• Configuring the Fibre Channel ports

2. Install and configure the host

• Loading the OS and software• Installing and configuring the HBAs• Clustering and fabric zoning• Fabric zoning and LUN security for multiple operating systems

3. Connect the disk array

• Defining the paths• Verifying host recognition of disk array devices

4. Configure disk array devices

• Changing the device parameters• Assigning the new devices to volume groups• Creating the Journaled File Systems• Mounting and verifying the file systems

Install and configure the disk arrayThe HP service representative performs these tasks:

• Assembling hardware and installing software• Loading the microcode updates• Installing and formatting devices

After these tasks are finished, you will use Remote Web Console, Command View (XP arrays only),Command View XP Advanced Edition, or LUN Configuration and Security Manager to complete theremaining tasks listed below. If you do not have these programs, your HP service representative canperform these tasks for you.

12 Installation

Setting the host mode and host group mode for the disk arrayports

After the disk array is installed, you must set the host mode for each disk array port to match the host OS.Set the host mode using LUN Manager in Remote Web Console (shown), Command View (XP arraysonly), or Command View XP Advanced Edition. If these are not available, the HP service representativecan set the host mode using the SVP. The host mode for AIX is 0F.

CAUTION:The correct host mode must be set for all new installations (newly connected ports) to AIX hosts. Do notselect a mode other than 0F for AIX. Changing a host mode after the host has been connected isdisruptive and requires the server to be rebooted.

When a new host group is added, additional host group modes (options) may be configured. Thestorage administrator must verify if an additional host group mode is required for the host group.


The following host group mode is available for AIX:

HostGroupMode Function Default Comments

2 VERITAS® Storage Foundation forOracle RAC, DBE+RAC DatabaseEdition/Advanced Cluster for RealApplication Clusters or if VERITAS® ClusterServer 4.0 or later with I/O fencing functionis used.

Inactive Previously MODE186Do not apply this optionto Sun Cluster.

CAUTION:Changing host group modes for ports where servers are already installed and configured is disruptiveand requires the server to be rebooted.

Setting the System Option ModesThe HP service representative sets the System Option Mode(s) based on the operating system andsoftware configuration of the host.

Configuring the Fibre Channel portsConfigure the disk array Fibre Channel ports by using Remote Web Console (shown), Command View(XP arrays only), or Command View XP Advanced Edition. Select the settings for each port based onyour storage area network topology. Use switch zoning if you connect different types of hosts to thearray through the same switch.

14 Installation

Fibre addressIn fabric environments, the port addresses are assigned automatically. In arbitrated loop environments,set the port addresses by selecting a unique arbitrated loop physical address (AL-PA) or loop ID for eachport. For specific values, refer to the HP StorageWorks LUN Configuration and Security Manager XPUser Guide applicable to your array.

Fabric and connection parameter settingsSet each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL as shown inthe following figure and table. For detailed topology information, refer to the HP StorageWorks SANDesign Reference Guide on the http://www.hp.com website.

Installing and configuring the HBAsInstall and configure the host bus adapters using the HBA manufacturer’s instructions.

Supported HBAsSupported HBAs include the IBM FC6228, IBM FC6239, and IBM FC5716 (XP12000 only).

To verify that the FC6227 drivers are installed:1. Use the lslpp command to display the drivers currently installed on the system.

Example

# lslpp -l | grep df1000f7

2. Check the list to see if the required drivers are installed. For the IBM FC6227 HBA, the followingdrivers are required:

devices.pci.df1000f7

devices.fcp.disk

If the drivers are not displayed, install the drivers by using the installp command or SMIT.

To check the firmware level:The HBA should have the proper version of firmware installed.

1. Use the lsdev command to display the device object.

Example

# lsdev -Cc adapter

2. Use the lscgfg command to display the firmware level.

Example

# lscgfg -vl fcsX

fcsX is the fiber device object (typically fcs0). The field “Devices Specific.(Z9)” shows the installedfirmware revision of the HBA.

To install the drivers using the AIX command line:1. Insert the IBM drivers CD.

2. Use the installp command to install the drivers.

Example

# installp -a -dlpfc.installp all

3. Use the lslpp command to verify that the drivers are installed on the system.

4. Configure the new devices by rebooting the system with the shutdown –r command or using thecfgmgr command to run Configuration Manager.

16 Installation

To install the drivers using SMIT:1. Insert the IBM drivers CD.

2. Start SMIT.

Example

# smit

The System Management screen appears.

3. Select Install Additional Software.

4. Select Input Device / Directory For Software and press F4 to select device.

5. Select Software To Install and press F4 to display a list of software.

6. Select the drivers needed using F7.

You can use the slash (“/”) to search for the components in the list.

HBA FC6227 requires these drivers:

devices.pci.df1000f7

devices.fcp.disk

7. Press Enter.

Wait for status to change from RUNNING to OK.

8. Check installation summary result (SUCCESS).

9. Press F10.

10. Use the smit devinst command to configure the devices.


Clustering and fabric zoningIf you plan to use clustering, install and configure the clustering software on the servers.

Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node.Multiple clusters compose a multi-cluster environment. The following example shows a multi-clusterenvironment with three clusters, each containing two nodes. The nodes share access to the disk array.

Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operatingsystem) or they may be heterogeneous (mixed operating systems). How you configure LUN security andfabric zoning depends on the operating system mix and the SAN configuration.

Fabric zoning and LUN security for multiple operating systemsYou can connect multiple clusters of various operating systems to the same switch and fabric usingappropriate zoning and LUN security as follows:

• Storage port zones may overlap if more than one operating system needs to share an array port.• Heterogeneous operating systems may share an XP array port if you use Secure Manager and set

the appropriate host group and mode. All others must connect to a dedicated XP array port.• Use Secure Manager for LUN isolation when multiple hosts connect through a shared array

port. Secure Manager provides LUN security by allowing you to restrict which LUNs each hostcan access.

18 Installation

Connect the disk arrayThe HP service representative connects the disk array to the host by:

1. Verifying operational status of the disk array channel adapters, LDEVs, and paths.

2. Connecting the Fibre Channel cables between the disk array and the fabric switch or host.

3. Verifying the ready status of the disk array and peripherals.

Defining the pathsUse Remote Web Console (shown), Command View (XP arrays only), or Command View XP AdvancedEdition to define paths (LUNs) between hosts and volumes in the disk array.

This process is also called “LUN mapping.” In Remote Web Console and Command View, LUN mappingincludes:

• Configuring ports• Enabling LUN security on the ports• Creating host groups• Assigning host bus adapter WWNs to host groups• Mapping volumes to host groups (by assigning LUNs)

In Command View XP Advanced Edition, LUN mapping includes:

• Configuring ports• Creating storage groups• Mapping volumes and WWN/host access permissions to the storage groups

For details see LUN Configuration and Security Manager XP User’s Guide or Command View XPAdvanced Edition Device Manager Web Client User’s Guide. Note the LUNS and their ports, WWNs,nicknames, and LDEVs for later use in verifying host and device configuration.


Verifying host recognition of disk array devices

To verify that the host recognizes the disk array devices:1. Log into the host as an administrator (root).

2. If the disk array LUNs are defined after the IBM system is powered on, issue a cfgmgr command torecognize the new devices.

3. Use the lsdev command to display system device data and verify that the system recognizes thenewly installed devices.

The devices are listed by device file name. All new devices should be listed as “Available.” If theyare listed as “Define,” you must do more configuration before they can be used.

Example

#lsdev -Cc diskhdisk0 Available 10-60-00-5, 0 16 Bit SCSI Disk Drivehdisk1 Available 10-60-00-6, 0 16 Bit SCSI Disk Drive

The example shows that Device hdisk0 is installed on bus 60 and has TID=5 and LUN=0.

4. Record the device file names for the new devices. You will use this information in changing thedevice parameters.

5. Use the lscfg command to find out the AIX disk device’s corresponding array LDEV designation.

Example

# lscfg –vl hdisk3

In this example, the emulation type, LDEV number, CU number and array port designation should allbe displayed for disk device hdisk3.

Configure disk array devicesDisks in the disk array are configured using the same procedure for configuring any new disk on the host.This includes the following procedures:

• Changing the device parameters• Assigning the new devices to volume groups• Creating the Journaled File Systems• Mounting and verifying the file systems

Creating scripts to configure all devices at once may save you considerable time.

Changing the device parametersWhen the device files are created, the system sets the device parameters to the system default values. Youmay need to change a few of those values for each new OPEN-x device (see table on next page):

• Read/write (R/W) timeout value• Queue depth• Queue type

20 Installation

Parameter Default Value Required Value

Read/write timeout 30 60

Queue type None Simple

Parameter Recommended Value

Queue depth per LU ≤ 32

Queue depth per port (MAXTAGS) ≤ 1024

The recommended queue depth settings may not provide the best I/O performance for your system. Youcan adjust the queue depth setting to optimize the I/O performance of the disk array.

To show the device parameters using the AIX command line:At the command line prompt, enter lsattr -E -l hdiskx, where hdiskx is the device file name.

Example

# lsattr –E -l hdisk2

To change the device parameters using the AIX command line:1. To change the R/W timeout parameter, enter:

chdev –1 hdiskx –a rw_timeout=’60’

2. To change the queue depth parameter, enter:

chdev –l hdiskx –a queue_depth=’x’

where x is a value from the above table.

3. To change the queue type parameter, enter:

chdev –l hdiskx –a q_type=’simple’

Example

# chdev –l hdisk3 –a queue_depth=’2’

This changes the queue depth for device hdisk3.

4. Verify that the parameters for all devices were successfully changed.

Example

# lsattr –E –l hdisk3

5. Repeat these steps for each OPEN-x device on the disk array.

TIP:The lsattr command also shows other useful information, such as LUN ID of the mappedLDEV, worldwide name of the disk array FC port, and N-Port ID.Another useful command for determining the slot position and port worldwide name of theHBA is the lscfg –v –l hdiskx command.


To change the device parameters using SMIT:1. Start SMIT. (Optional) For an ASCII session, use the smit –C command.

2. Select Devices.

4. Verify that the file system is usable by performing some basic operations (for example, file creation,copying, and deletion) on each logical device.

Example

# cd /hp00

# cp /smit.log /hp00/smit.log.back1

# ls -l hp00

–rw-rw-rw- 1 root system 375982 Nov 30 17:25 smit.log.back1

# cp smit.log.back1 smit.log.back2

# ls -l

-rw-rw-rw- 1 root system 375982 Nov 30 17:25 smit.log.back1

-rw-rw-rw- 1 root system 375982 Nov 30 17:28 smit.log.back2

# rm smit.log.back1# rm smit.log.back2

5. Use the df command to verify that the file systems have successfully automounted after a reboot.Any file systems that were not automounted can be set to automount using the SMIT Change aJournaled File System screen.

If you are using HACMP or HAGEO, do not set the file systems to automount.

Example

# df

File system 512-blocks free %Used Iused %Iused Mounted on

/dev/hd4 8192 3176 61% 652 31% //dev/hd2 1024000 551448 46% 6997 5% /usr

2 Troubleshooting

This section includes resolutions for various error conditions you may encounter.

If you are unable to resolve an error condition, ask your HP support representative for assistance. SeeCalling the HP support center.


Error conditionsDepending on your system configuration, you may be able to view error messages (R-SIMS) as follows:

• In Remote Web Console (Status tab)• In Command View Advanced Edition (Alerts window)• In Command View (Event History or Event Notification windows) (XP arrays only)

Error condition Recommended action

The logical devices are notrecognized by the host.

Verify that the READY indicator lights on the disk array are ON.Verify that fiber cables are correctly installed and firmly connected.Verify that the target IDs are properly configured. The LUNs for eachTID must start at 0 and continue sequentially without skipping anynumbers.Verify that the TIDs/WWNs on each bus are unique. Do not installtwo devices with the same ID on the same bus.Recheck the busesfor new devices.Verify that LUSE devices are not intermixed with normal LUNs onthe same port.Verify that the maximum number of LUSE devices per port has notbeen exceeded.Verify that the disk array host mode is set correctly.

The host does not reboot properlyafter hard shutdown.

If you power off the host without executing the shutdown process,wait three minutes to allow the disk array’s internal timeout process topurge queued commands. If the host restarts while the disk array isprocessing queued commands, the host may not reboot successfully.

Physical volumes cannot be created. Verify that the disk array logical devices are correctly formatted.

Logical volumes cannot be created. Verify that the volume capacity for OPEN-x volumes is not greaterthan the maximum capacity allowed. See Appendix B, Disk arraysupported emulations.Verify that the capacity of the volume group is not less than the totalcapacity of the partitioned logical volume.

A file system is not mounted afterrebooting.

Verify that the host was restarted correctly.Verify that the file system attributes are correct.

The disk array performs a self rebootbecause the disk array was busy orit logged a panic message.

Reboot the host.

The disk array responds “Not Ready”or the disk array has displayed “NotReady” and timed out.

Contact HP.

The host detects a parity error. Check the HBA and make sure it was installed properly. Reboot thehost.

The host hangs or devices aredeclared and the host hangs.

Make sure there are no duplicate disk array TIDs and that disk arrayTIDs do not conflict with any host TIDs.

*Capacity = (512 x number of blocks) ÷ 10242

Note 1:The availability of an emulation depends on the disk array.

Note 2:The devices are defined to the host as SCSI disk devices, even though the interface is Fibre Channel.

Note 3:The device capacity can sometimes be changed by the BIOS or host adapter board. This may makeactual capacity different from that listed in the table.

36 Disk array supported emulations

Note 4:The number of blocks for a CVS volume is calculated as follows:

# of blocks = (# of cylinders) × (# of heads) × (# of sectors per track)

Example

For an OPEN-3 CVS volume with capacity = 37 MB:# of blocks = (53 cylinders–see Note 5) × (15 heads) ×(96 sectors per track) = 76320

Example

For an OPEN-V CVS volume with capacity = 49 MB:# of blocks = (53 cylinders–see Note 5) × (15 heads) ×(128 sectors per track) = 101760

Note 5:The number of cylinders for a CVS volume is calculated as follows (↑…↑ means that the value should berounded up to the next integer):

OPEN-3/8/9/E: The number of cylinders for a CVS volume = # of cylinders = ↑ (capacity (MB) specifiedby user) × 1024/720 ↑

ExampleFor an OPEN-3 CVS volume with capacity = 37 MB:# of cylinders = ↑37 × 1024/720↑ = ↑52.62↑(rounded up to next integer) = 53 cylinders

OPEN-V: The number of cylinders for a CVS volume = # of cylinders = ↑ (capacity (MB) specified byuser) × 16/15 ↑

Example

For an OPEN-V CVS volume with capacity = 49 MB:# of cylinders = ↑49 × 16/15↑ = ↑52.26↑(rounded up to next integer) = 53 cylinders

OPEN-3/8/9/E: The number of cylinders for a CVS LUSE volume = # of cylinders = ↑ (capacity (MB)specified by user) × 1024/720 ↑ × n

Example

For a CVS LUSE volume with capacity = 37 MB and n = 4:# of cylinders = ↑37 × 1024/720↑ × 4 = ↑52.62↑× 4 = 53 × 4 = 212

OPEN-V: The number of cylinders for a CVS LUSE volume = # of cylinders = ↑ (capacity (MB) specifiedby user) × 16/15 ↑ × n

Example

For an OPEN-V CVS LUSE volume with capacity = 49 MB and n = 4:# of cylinders = ↑49 × 16/15↑ × 4 = ↑52.26↑× 4 = 53 × 4 = 212

Note 6:The capacity of an OPEN-3/8/9/E CVS volume is specified in MB, not number of cylinders. The capacityof an OPEN-V CVS volume can be specified in MB or number of cylinders. You set the volume size usingRemote Web Console, Command View (XP arrays only), or Command View XP Advanced Edition.

Notes for disk parameters1. The value of pc is calculated as follows:

pc = nc nt ns

The nc of OPEN-x CVS corresponds to the capacity specified by SVP or remote console.

The CVS size of OPEN-x is specified by capacity (megabyte), not by number of cylinders.

The number of cylinders of an OPEN-x CVS volume can be obtained by the following calculation (↑↑means round up to integer).

The number of cylinders = ↑ (specified capacity in megabytes from SVP or remote console) × 1,024/ 720 ↑.

Example

When 37 MB is specified for an OPEN-3 CVS volume from SVP,the number of cylinders of the OPEN-3 CVS can becalculated as follows:

37 × 1,024 / 720 = 52.62↑52.62↑ = 53

The OPEN-3 CVS volume has 53 cylinders.

2. The value of pa must be equal to or more than 131,072.

3. The number of cylinders of a Logical Unit Size Expansion (LUSE) composed of OPEN-x CVS volumescorresponds to the capacity specified by the SVP or the remote console. CVS size of OPEN-x isspecified by the capacity (megabytes), not by the number of cylinders. The number of cylinders of theOPEN-x CVS volume can be obtained by the following calculation (↑ ↑ means round up to integer):

The number of cylinders = ↑ (specified capacity in megabytes from SVP or remote console) ×1,024 / 720 ↑ × n

where n is the number of concatenated volumes for LUSE.

Example

When 37 MB is specified for the OPEN-3 CVS volume and thefour volumes are concatenated, the number of cylinders ofthe OPEN-3 CVS can be calculated as follows:

↑37 × 1,024 / 720↑ × 4 = ↑52.62↑ × 4 = 53 × 4 = 212

The LUSE for the OPEN-3 CVS volume has 212 cylinders.

HP StorageWorks Command View XP, a software product for managing XParrays. Command View runs on a Windows-based management workstation.

Command ViewXP Advanced Edi-tion (CVXP AE)

HP StorageWorks Command View XP Advanced Edition, installs on theuser-provided Device Manager server and provides a browser-based platformfrom which you can manage the SVS200 and the XP family of disk arrays—evenglobally distributed arrays.

command device A volume on the disk array that accepts Continuous Access or Business Copycontrol operations which are then executed by the disk array.

CU Control Unit. Contains LDEVs and is approximately equivalent to SCSI Target ID.

CVS Custom volume size. CVS devices (OPEN-x CVS) are custom volumes configuredusing array management software to be smaller than normal fixed-size OPENsystem volumes. Synonymous with volume size customization (VSC).

DKC The array cabinet that houses the channel adapters and service processor (SVP).

DKU (disk cabinetunit)

The array cabinets that house the disk array physical disks.

emulation modes The logical devices (LDEVs) associated with each RAID group are assigned anemulation mode that makes them operate like OPEN system disk drives. Theemulation mode determines the size of an LDEV:OPEN-3: 2.46 GBOPEN-8: 7.38 GBOPEN-9: 7.42 GBOPEN-E: 13.56 GBOPEN-L: 36 GBOPEN-V: User-defined custom size

failover Disconnecting a failed unit or path and replacing it with an alternative unit orpath in order to continue functioning.

FC Fibre Channel.

FC-AL Fibre Channel arbitrated loop.

FCP Fibre Channel Protocol.

GB Gigabytes.


HBA Host bus adapter.

host mode Each port can be configured for a particular host type. These modes arerepresented as two-digit hexadecimal numbers. For example, host mode 08represents an HP-UX host.

LDEV Logical device. An LDEV is created when a RAID group is carved into piecesaccording to the selected host emulation mode (that is, OPEN-3, OPEN-8,OPEN-L). The number of resulting LDEVs depends on the selected emulationmode. The term LDEV is often used synonymously with the term volume.

LUN Logical unit number. A LUN results from mapping a SCSI logical unit number,port ID, and LDEV ID to a RAID group. The size of the LUN is determined by theemulation mode of the LDEV and the number of LDEVs associated with the LUN.For example, a LUN associated with two OPEN-3 LDEVs has a size of 4,693 MB.

LUSE A LUN is normally associated with only a single LDEV. The LUSE feature allowsa LUN to be associated with 1 to 36 LDEVs. Essentially, LUSE makes it possiblefor applications to access a single large pool of storage. The LUSE feature isavailable when the HP StorageWorks LUN Configuration Manager product isinstalled.

OFC Open Fibre Control.

OPEN-x A general term describing any one of the supported OPEN emulation modes(for example, OPEN-L).

OS Operating system.

PA Physical address.

path “Path” and “LUN” are synonymous. Paths are created by associating a port, atarget, and a LUN ID with one or more LDEVs.

port A physical connection that allows data to pass between a host and the diskarray. The number of ports on an XP disk array depends on the number ofsupported I/O slots and the number of ports available per I/O adapter. TheXP family of disk arrays supports Fibre Channel (FC) ports as well as otherport types. Ports are named by port group and port letter, such as CL1-A. CL1is the group, and A is the port letter.

RAID Redundant array of independent disks.

remote console PC The PC running HP StorageWorks Remote Control XP.

Remote Control(RC)

HP StorageWorks Remote Control XP. A software product used for managingXP arrays.

Remote Web Con-sole (RWC)

HP StorageWorks XP Remote Web Console. A browser-based program installedon the SVP that allows you to configure and manage the disk array.

R-SIM Remote service information message.

SCSI Small computer system interface.

SIM Service information message.

SNMP Simple Network Management Protocol.

SVP Service processor, which is the PC built into the disk controller. The SVPprovides a direct interface into the disk array. SVP use is reserved for HPsupport representatives only.

SVS Storage Virtualization System, an appliance that manages multiple disk arraystorage systems.

52 Glossary

TB Terabyte.

TID Target ID.

Volume On the XP array, a volume is a uniquely identified virtual storage devicecomposed of a control unit (CU) component and a logical device (LDEV)component separated by a colon. For example 00:00 and 01:00 are twouniquely identified volumes; one is identified as CU = 00 and LDEV = 00, andthe other as CU = 01 and LDEV = 00; they are two unique separate virtualstorage devices within the XP array.

VSC Volume size customization. Synonymous with CVS.

WWN World Wide Name. A unique identifier assigned to a Fibre Channel device.
