1 Installing and configuring HP-UX for the XP disk array You and your HP service representative each play a role in installation. Your 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 your HP service representative. Features and requirements Ask your HP service representative about the latest supported hardware and software.
Device emulation types The XP family of disk arrays and the SVS200 support these device emulation types: • OPEN-K/3/8/9/E 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. 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, you must designate at least one LDEV as a command device. This can be done with XP Remote Web Console, XP Command View (XP arrays only), or Command View XP Advanced Edition Software.
• Setting and verifying the auto-mount parameters 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 After these tasks are finished, you will use XP Remote Web Console, XP Command View (XP arrays only), Command View XP Advanced Edition Software, or XP Array Manager to complete the remaining tasks listed below.
The following host group modes (options) are available for HP-UX: Table 2 Host group modes (options) Host Group Mode Function Default Comments 12 Deletion of Ghost LUN Inactive Previously MODE280 33 Task retry ID enable Inactive (HP-UX 11.31 only CAUTION: Changing host group modes for ports where servers are already installed and configured is disruptive and requires the server to be rebooted.
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. 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 table and figures.
Fabric parameter Connection parameter Provides ON FC-AL NL-port (private arbitrated loop) OFF Direct Fabric Attach Not supported Installing and configuring the host This section explains how to install and configure the host and host bus adapters (HBAs) that connect the host to the disk array. Loading the operating system and software Follow the manufacturer's instructions to load the operating system and software onto the host.
Fabric zoning and LUN security for multiple operating systems You can connect multiple clusters of various operating systems to the same switch and fabric using appropriate 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.
In Command View XP 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 Command View XP Advanced Edition Software 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.
To verify device recognition: 1. Log in to the system as root. 2. 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 insf –e to build all missing device files. Example # ioscan -fn Class I H/W Path bc 6 14 fc 1 14/12 lan 2 14/12.5 fcp 1 14/12.8 ext_bus 6 14/12.8.0.0.0 disk 4 14/12.8.0.0.0.0.
5. SCSI bus instance number Hardware path SCSI TID LUN File name 00 14/12.6.1 6 2 c6t0d1 Verify that the SCSI TIDs correspond to the assigned port address for all connected ports (see mapping tables in Appendix B - Disk array device emulations, for values). If so, the logical devices are recognized properly. If the logical devices are not recognized properly: • Check the AL-PA for each port using the LUN Manager software.
However, some HP-compatible systems do not create the device files automatically. If verification shows that the device files were not created, follow the instructions in Creating the device files. The following procedure verifies both types of device files: 1. Display the block-type device files in the /dev/dsk directory using the ls –l command with the output piped to more. Verify there is one block-type device file for each disk array device.
Creating the device files If the device files were not created automatically when the system was restarted, use the insf –e command in the /dev directory to create the device files. After this command is executed, repeat the procedures in the previous section Verifying device recognition to verify new device recognition and the device files and driver. Example # insf -e insf: Installing special files for mux2 instance 0 address 8/0/0 : : : : : : : : # Failure of the insf –e command indicates a SAN problem.
# cd /dev/dsk Go to /dev/dsk directory. # mknod /dev/dsk/c2t6d0 b 31 0x026000 File name, b=block-type, 31=major #, 0x026000= minor # Create block-type file. # cd /dev/rdsk Go to /dev/rdsk directory. # mknod /dev/rdsk/c2t6d0 c 188 0x026000 Create character-type file. File name, c=character-type, 177=major #, 0x026000=minor # : # The character-type device file is required for volumes used as raw devices (for example, 3390-3A/B/C).
Creating new volume groups You must create new volume groups for the new physical volumes. If desired, you can also add any of the volumes on the disk array to existing volume groups using the vgextend command. The physical volumes that make up one volume group can be located either in the same disk array or in other disk arrays. To allow more volume groups to be created, use SAM to modify the HP-UX system kernel configuration.
Volume group configuration for /dev/vg06 has been saved in /etc/1vmconf/vg06.conf. For Logical Unit Size Expansion (LUSE) volumes that contain more than 17 OPEN-8/9 LDEVs or more than 7043 MB (OPEN-8/9*n-CVS), use the –s and –e physical extent (PE) parameters of the vgcreate command. See “LUSE device parameters” on page 42. If you need to delete a volume group, use the vgremove command (for example, vgremove /dev/vgnn).
Example lvextend –L size /dev/vgnn/lvolx lvreduce Decreases the size of an existing logical volume. Any file system attached to the logical volume must be unmounted before executing the lvreduce command. Example 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: 1.
character device "/dev/vg06/rlvol1". Logical volume "/dev/vg06/lvol1" has been successfully extended. Volume Group configuration for /dev/vg06 has been saved in /etc/1vmconf/vg06.conf. 3. Use the lvdisplay command to verify that the logical volume was created correctly.
# newfs /dev/vg06/rlvol1 create file system newfs: / etc/default/fs determine the file system type mkfs (hfs): ... : 7188496, 7198520, 7208544 # Example 3 # newfs -F vxfs /dev/vg06/rlvol1 : # newfs -F hfs /dev/vg06/rlvol2 2. Specify file system type Repeat step 1 for each logical volume on the disk array. Setting the I/O timeout parameter Set the I/O timeout value for each disk device to 30 seconds. 1.
PV Name VG Name PV Status : Stale PE IO Timeout (Seconds) 4. /dev/dsk/c0t6d0 /dev/vg06 available 0 30 [New I/O timeout value] Repeat the above steps for each new disk connected to the system. Creating the mount directories Create a mount directory for each logical volume. Choose a unique name for each mount directory that identifies the logical volume. To create a mount directory for each logical volume: 1. Use mkdir with the new mount directory name as the argument to create the mount directory.

Glossary AL Arbitrated loop. 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). All RAID6 array groups are made up of 8 HDDs (6D+2P).
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-L). The number of resulting LDEVs depends on the selected emulation mode. The term LDEV is often used synonymously with the term volume. LUN Logical unit number.
component separated by a colon. For example 00:00 and 01:00 are two 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. VSC Volume size customization. Synonymous with CVS. WWN World Wide Name. A unique identifier assigned to a Fibre Channel device.
