Page 7: Installing And Configuring Hp-Ux For The Xp Disk Array
1 Installing and configuring HP-UX 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. -
Page 8: Device Emulation Types
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. -
Page 9: Snmp Configuration
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. -

Page 11: Setting The System Option Modes
When a new host group is added, additional host group modes (options) may be configured. The storage administrator must verify if an additional host group mode is required for the host group. The following host group modes (options) are available for HP-UX: Table 1 Host group modes (options) Host Group... -
Page 12: Fibre Address
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. -

Loading the operating system and software Follow the manufacturer's instructions to load the operating system and software onto the host. -
Page 14: Fabric Zoning And Lun Security For Multiple Operating Systems
WARNING! For OpenVMS HP recommends that a volume be presented to one OpenVMS cluster or stand alone system at a time. Volumes should not be presented to allow them to move between stand alone systems and/or OpenVMS clusters, as this can lead to corruption of the OpenVMS volume and data loss. -
Page 15: Verifying Fca Installation
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. - Page 16 To verify device recognition: Log in to the system as root. Display the device data to verify that the system recognizes the newly installed devices on the disk array. Use the ioscan fn command to display the device data. On a system with a large LUN configuration, HP-UX may not build device files on all LUNs. Enter e to build all missing device files.
-
Page 17: Configuring Disk Array Devices
Construct the device file name for each device, using the device information, and enter the file names in your table. Use the following formula to construct the device file name: cxtydz where: x = SCSI bus instance number y = SCSI target ID z = LUN c stands for controller t stands for target ID... -
Page 18: Verifying The Device Files And Drivers
Mounting and verifying the file systems 10. Setting and verifying the auto-mount parameters The HP-UX system uses the Logical Volume Manager (LVM) to manage the OPEN-x devices on the disk array. The instructions in this section do not explicitly cover all LVM configuration issues. For further information on LVM configuration, see the HP-UX user documentation. -
Page 19: Creating The Device Files
After verifying the block-type and character-type device files, verify the HP-UX driver for the disk array using the ioscan fn command. Example # ioscan -fn Class I H/W Path Driver S/W State H/W Type Desc ------------------------------------------------------------ root CLAIMED BUS_NEXUS... CLAIMED BUS_NEXUS... -
Page 20: Device Information Example
Construct the minor number for each device, using the device information, and enter the file names in your table. Use the following formula to construct the minor number: 0xxxyz00 where xx = SCSI bus instance number, y = SCSI target ID, and z = LUN. Display the driver information for the system using the lsdev command. -
Page 21: Creating The Physical Volumes
Creating the physical volumes A physical volume must be created for each new SCSI disk device. To create the physical volumes: Use the pvcreate command to create the physical volumes with the character-type device file as the argument. Specify the /dev/rdsk directory. Example # pvcreate /dev/rdsk/c6t0d0 Physical volume "/dev/rdsk/c6t0d0"... - Page 22 Choose a unique minor number for the new group file in sequential order (for example, when existing volume groups are vg00-vg05 and the next group name is vg06, use minor number 06 for the vg06 group file). The minor numbers are hexadecimal (for example, the 10th minor number is 0x0a0000). Use mknod to create the group file for the new directory.

Page 23: Creating Logical Volumes
Use vgdisplay v to verify that the volume group was created correctly. The v option displays the detailed volume group information. Example # vgdisplay v /dev/vg06 - - - Volume groups - - - VG Name /dev/vg06 VG Write Access read/write VG Status available... - Page 24 lvreduce L size /dev/vgnn/lvolx CAUTION: Data within the file system can be lost after execution of lvreduce. Create logical volumes after you create volume groups. A logical volume must be created for each new SCSI disk device. To create logical volumes: Use the lvcreate L command to create a logical volume.

Page 25: Creating The File Systems
Use the lvdisplay command to verify that the logical volume was created correctly. Example # lvdisplay /dev/vg06/lvol1 - - - Logical volume - - - LV Name /dev/vg06/lvol1 VG Name /dev/vg06 LV Permission read/write LV Status available/syncd Mirror copies Consistency Recovery Schedule parallel LV Size (Mbytes) -
Page 26: Setting The I/O Timeout Parameter
To create file systems: Use the newfs command to create the file system using the logical volume as the argument. Example 1 # newfs /dev/vg06/rlvol1 newfs: /etc/default/fs determine the file system type mkfs (hfs): Warning -272 sectors in the last cylinder are not allocated. -

Use mkdir with the new mount directory name as the argument to create the mount directory. Example # mkdir /AHPMD-LU00 Use the ls x command to verify the new mount directory. Example The following example shows the root directory as the location for the mount directories. # ls -x AHPMD-LU00 device... -
Page 29: Setting And Verifying The Auto-Mount Parameters
As a final verification, perform some basic UNIX operations (for example file creation, copying, and deletion) on each logical device to make sure that the devices on the disk array are fully operational. Example #cd /AHPMD-LU00 #cp /bin/vi /AHPMD-LU00/vi.back1 #ls -l drwxr-xr-t 2 root root 8192 Mar 15 11:35 lost+found -rwxr-xr-x 1 root sys 217088 Mar 15 11:41 vi.back1 #cp vi.back1 vi.back2... -
Page 30: Auto-Mount Parameters
To set up and verify the auto-mount parameters: Edit the /etc/checklist (/etc/fstab) file to add a line for each OPEN-x device on the disk array. This example and the following table show the auto-mount parameters. Example #cp -ip /etc/checklist /etc/checklist.standard #vi /etc/checklist /dev/vg00/lvol1 # root... -

Page 49: Glossary
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). - Page 50 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.
