HP StorageWorks XP Disk Array Configuration Guide for Linux HP XP24000 Disk Array HP XP20000 Disk Array HP XP12000 Disk Array HP XP10000 Disk Array HP 200 Storage Virtualization System Abstract This guide provides requirements and procedures for connecting an XP disk array or SVS 200 to a host system, and for configuring the disk array for use with the Linux operating system.
1 Installing and configuring Linux for the XP disk array You and the HP service representative each play a role in installation. The HP service representative is responsible for installing the disk array and formatting the disk devices. You are responsible for configuring the host server for the new devices with assistance from the HP service representative.
Connection speeds of 1 Gbps, 2 Gbps, and 4 Gbps 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 array devices are defined to the host as SCSI disks.
SNMP configuration The XP family of disk arrays and the SVS 200 support standard Simple Network Management Protocol (SNMP) for remotely managing arrays. The SNMP agent on the service processor (SVP) performs error-reporting operations requested by the SNMP manager. SNMP properties are usually set from the SVP but they can also be set remotely using XP Remote Web Console or XP Command View Advanced Edition Software.

The following host group mode (option) is available for Linux: Table 1 Host group mode (option) Host Group Function Default Comments Mode Previously MODE249 Reporting Unit Attention when adding LUN Inactive CAUTION: Changing host group modes for ports where servers are already installed and configured is disruptive and requires the server to be rebooted.
Fabric and connection parameter settings Set each array port to FABRIC ON or OFF with connections of POINT-TO-POINT or FC-AL as shown in the following figures and table. For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide at http://www.hp.com/go/sandesign.
Fibre address In 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 each port. For specific values, refer to the HP StorageWorks XP LUN Manager User's Guide applicable to your array.
Figure 3 Multi-cluster environment Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operating system) or they may be heterogeneous (mixed operating systems). How you configure LUN security and fabric zoning depends on the operating system mix and the SAN configuration. WARNING! For OpenVMS HP recommends that a volume be presented to one OpenVMS cluster or stand...
Connecting the disk array The HP service representative connects the disk array to the host by: Verifying operational status of the disk array channel adapters, LDEVs, and paths. Connecting the Fibre Channel cables between the disk array and the fabric switch or host. Verifying the ready status of the disk array and peripherals.
Verify that the system recognizes the disk array partitions by viewing the /proc/partitions file. Example #cat /proc/partitions major minor #blocks name rmerge rsect 7211520 7181087 sda1 28272 sda2 7211520 7181087 sdb1 28272 sdb2 7211520 7181087 sdc1 28272 sdc2 7211520 7181087 sdd1 28272 sdd2...
In XP Command View Advanced Edition Software, LUN mapping includes: Configuring ports Creating storage groups Mapping volumes and WWN/host access permissions to the storage groups For details see the HP StorageWorks XP LUN Manager User s Guide or the HP StorageWorks XP Command View Advanced Edition Software Device Manager Web Client User s Guide.
Select p to display the present partitions. Select n to make a new partition. You can make up to four primary partitions or you can make one extended partition. The extended partition can be divided into a maximum of 11 logical partitions, which can be assigned partition numbers from 5 to 15.
Creating the mount directories Create mount directories using the mkdir command. Choose names for the mount directories which identify both the logical volume and partition. Enter mkdir /mnt/mount_point. Example # mkdir /mnt/A5700F_LU00 Repeat step 1 for each device on the disk array. Creating the mount table Add the new devices to the /etc/fstab file to specify the automount parameters for each device.

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. Error conditions Depending on your system configuration, you may be able to view error messages (R-SIMS) as follows: In XP Remote Web Console (Status tab) In XP Command View Advanced Edition Software (Alerts window) In XP Command View (Event History or Event Notification windows) (XP arrays only)

B Disk array supported emulations This appendix provides information about supported emulations and device type specifications. Some parameters may not be relevant to your array. Consult your HP representative for information about supported configurations for your system. Supported emulations HP recommends using OPEN-V as the emulation for better performance and features that may not be supported with the legacy emulations (OPEN-[389LE]).

Note 2: The devices are defined to the host as SCSI disk devices, even though the interface is Fibre Channel. Note 3: The command device (used for XP Raid Manager) is distinguished by -CM on the product name (for example, OPEN-3-CM, OPEN-3-CVS-CM). Note 4: The device capacity can sometimes be changed by the BIOS or host adapter board.

OPEN-V: The number of cylinders for a CVS LUSE volume = # of cylinders = (capacity (MB) specified by user) × 16/15 × n Example For an OPEN-V CVS LUSE volume with capacity = 49 MB and n = 4: # of cylinders = 49 ×...
C HP Cluster Gateway deployments The HP Cluster Gateway and HP Scalable NAS software both use the HP PolyServe software as their underlying clustering technology and both have very similar requirements for the XP disk array. They have both been tested with the XP disk arrays and this appendix details configuration requirements specific to XP deployments using HP PolyServe Software on Linux.
Membership partitions HP Scalable NAS uses a set of membership partitions to control access to the SAN and to store the device naming database, which includes the global device names that HP Scalable NAS assigns to the SAN disks placed under its control. The membership partitions must be placed on the SAN, not on local storage.
Glossary AL-PA Arbitrated loop physical address. array group A group of 4 or 8 physical hard disk drives (HDDs) installed in an XP disk array and assigned a common RAID level. RAID1 array groups consist of 4 (2D+2D) or 8 HDDs (4D+4D). RAID5 array groups include a parity disk but also consist of 4 (3D+1P) or 8 HDDs (7D+1P).

OPEN-E). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term volume. 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 the emulation mode of the LDEV and the number of LDEVs associated with the LUN.
