HP StorageWorks XP Disk Array Configuration Guide for Tru64 UNIX HP XP24000 Disk Array HP XP20000 Disk Array HP XP12000 Disk Array HP XP10000 Disk Array This guide provides requirements and procedures for connecting an XP disk array to a host system, and for configuring the disk array for use with the Tru64 UNIX operating system.
1 Installing and configuring Tru64 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.
Device emulation types The XP family of disk arrays supports these device emulation types: • OPEN-x devices: OPEN-x logical units represent disk devices. Except for OPEN-V, these devices are based on fixed sizes. OPEN-V is a user-defined size based on a CVS device. Supported emulations include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.

Figure 1 SNMP configuration XP RAID Manager command devices HP StorageWorks XP RAID Manager manages HP StorageWorks XP Business Copy Software or HP StorageWorks XP Continuous Access Software operations from a host server. To use XP RAID Manager with XP Business Copy Software or XP Continuous Access Software, you use XP Remote Web Console or XP Command View, to designate at least one LDEV as a command device.
Installing and configuring the disk array The HP service representative performs these tasks: • Assembling hardware and installing software • Loading the microcode updates • Installing and formatting devices • Configuring array groups and creating LDEVs After these tasks are finished, use XP Remote Web Console, XP Command View, or XP Array Manager to complete the remaining tasks listed below.
Setting the host mode and host group mode for the disk array ports After the disk array is installed, you must set the host mode for each host group that is configured on a disk array port to match the host OS. Set the host mode using LUN Manager in XP Remote Web Console (shown), or XP Command View.
The following host group mode (option) is available for Tru64: Table 2 Host group mode (option) Host Group Mode Function Default Comments Enable use of XP Continuous Access Software Previously MODE272 Inactive on Tru64 TruClusters. CAUTION: Changing host group modes for ports where servers are already installed and configured breaks all LUN paths and will require the paths to be redefined.
Fibre address In fabric environments, the port addresses are assigned automatically. Fabric and connection parameter settings Set each array port to FABRIC ENABLE with connections of POINT-TO -POINT (P-to-P). For detailed topology information, refer to the HP StorageWorks SAN Design Reference Guide available at: http://www.hp.com/go/sandesign.

Configuring system files Configure the Tru64 system to recognize the FCA as explained in the Tru64 Installation Guide or New Hardware Delivery (NHD) kit. This consists of booting genvmunix and executing doconfig (as explained in the Installation Guide). This can also be done by editing the system kernel configuration file as explained below.
• 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 host can access.
Verifying host recognition of disk array devices Use the hwmgr show scsi command at the UNIX prompt to see the list of new disk array devices. The device files are created automatically in Tru64 UNIX during system startup. Device files are created for each logical unit.
Refer to Tru64 UNIX System Administration for detailed procedures. Writing the partition labels Use the disklabel command to label the partition for each logical unit. Partition c specifies the entire area in the logical unit. Check that no errors are found in the partition settings after the labeling. You can edit the disk partition size using the disklabel command with option –e.
Create a new fileset in the new or existing advanced file system domain. # mkfset domain_name fileset_name Creating mount directories Create a mount directory for each device. Assign each mount directory a unique name that identifies the device being mounted. Create a mount directory.
Mounting an advanced file system: Mount the file system: # mount –t advfs domain_name#fileset_name mount_directory Example To mount the file system with mount directory: mount –t advfs domain1#fileset1 /HP5700_LU2c Assign the appropriate ownership and permissions: # chown owner:group*device_file_name* Example To assign ownership to dsk10c with owner Oracle, group dba, enter: chown oracle:dba *dsk10c* Verifying the file systems Verify that the new file systems were created correctly and are functioning properly.
Copy a file to the new device again: # cp /filename file_name.back2 Example To copy the same file again, enter: cp /vmunix vmunix.back2 List the files in the current directory: Example # ls –l The vmunix.back1 and vmunix.back2 files should be shown. Delete the files you copied: # rm file_name Example...
After first making a backup copy of the file, edit the /etc/fstab file. Add a line for each new device to be mounted. Example #vi /etc/fstab /dev/disk/dsk4a / ufs rw 1 1 /proc /proc procfs rw 0 0 /dev/disk/dsk12a /usr ufs rw 1 2 /dev/disk/dsk12b swap1 ufs rw 0 2 /dev/disk/dsk15c /HP5700_LU2c ufs rw 1 3 Table 4 Automatic mounting example explanation...
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: •...

Error condition Recommended action Verify that the host was restarted correctly. A file system is not mounted after re- booting. Verify that the file system attributes are correct. The disk array performs a self reboot because the disk array was busy or it Reboot the host.

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]).
Emulation Category Product name Blocks Sector # of Heads Sectors Capacity size (Note 1) (Note 2) (Note 3) (512 bytes) cylinders (Note 4) (bytes) track LUSE OPEN-3*n SCSI disk OPEN-3*n 4806720*n 3338*n 2347*n OPEN-8*n SCSI disk OPEN-8*n 14351040*n 9966*n 7007*n OPEN-9*n SCSI disk OPEN-9*n...

Note 4: The device capacity can sometimes be changed by the BIOS or host adapter board. This may make actual capacity different from that listed in the table. Note 5: The number of blocks for a CVS volume is calculated as follows: # of blocks = (# of cylinders) ×...
Page 32
Note 7: The capacity of an OPEN-3/8/9/E CVS volume is specified in MB, not number of cylinders. The capacity of an OPEN-V CVS volume can be specified in MB or number of cylinders. You set the volume size using XP Remote Web Console or XP Command View. Disk array supported emulations...
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).

host mode Each port can be configured for a particular host type. These modes are represented as two-digit hexadecimal numbers. For example, host mode 08 represents an HP-UX host. LDEV Logical device. An LDEV is created when a RAID group is carved into pieces according to the selected host emulation mode (that is, OPEN-3, OPEN-8, OPEN-E).

uniquely identified volumes; one is identified as CU = 00 and LDEV = 00, and the other as CU = 01 and LDEV = 00; they are two unique separate virtual storage devices within the XP array. Volume size customization. Synonymous with CVS. World Wide Name.
