1 Installing and configuring OpenVMS 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. -

The following host group mode (option) is available for OpenVMS: Table 2 Host mode setting Host Mode Description Use this host mode to enable the option that sets the UUID Procedure to set UUID HP recommends OpenVMS customers use Host Mode Option 33 to enable the UUID feature. This increases the capabilities for OpenVMS hosts that access the XP disk array, by (1) allowing CU:LDEVs above 7F:FF to be presented to the OpenVMS hosts and (2) allowing the OpenVMS system adminstrator to define the DGA device number to present to the OpenVMS host. -

In the tree, select a host group. The LU Path list displays showing information about LU paths associated with the selected host group. -
Page 14: Setting The System Option Modes
CAUTION: The correct host mode must be set for all new installations (newly connected ports) to OpenVMS hosts. Do not select a mode other than 05 for OpenVMS. Changing a host mode after the host has been connected is disruptive and requires the server to be rebooted. Setting the system option modes The HP service representative sets the system option mode(s) based on the operating system and software configuration of the host. -

Installing and configuring the host This section explains how to install and configure Fibre Channel adapters (FCAs) 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. Load all OS patches and configuration utilities supported by HP and the FCA manufacturer. -

Page 17: 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 18 Configuring ports Enabling LUN security on the ports Creating host groups Assigning Fibre Channel adapter WWNs to host groups Mapping volumes (LDEVs) to host groups (by assigning LUNs) Path configuration for OpenVMS requires the following steps: Define a single “command device” LUN per XP array and present it to the OpenVMS hosts across all connected paths.

Page 19: Verifying Disk Array Device Recognition
$run sys$system:sysman sysman> set environment/cluster sysman> io autoconfigure/log Now, verify the online status of the XP LUNs. Also, confirm that all expected LUNs are shown online. Verifying disk array device recognition Verify that the host recognizes the disk array devices: Enter the show device dg command: $ show device dg Check the list of peripherals on the host to verify the host recognizes all disk array devices. -
Page 20: Verifying File System Operation
Verifying file system operation Use the show device d command to list the devices: Example $ show device dg NOTE: Use the show device/full dga100 command to show the path information for the device: Example: $ show device/full $1$dga100: Disk $1$DGA100: (NODE01), device type HP OPEN-V, is online, file-oriented device, shareable, device has multiple I/O paths, served to cluster via MSCP Server, error logging is enabled. - Page 21 Change to the new directory: Example $ set default $1$dga100:[user] Verify that this directory exists: Example $ show default $1$dga100:[user] If the user directory does not exist, OpenVMS returns an error. Create a test user file: Example $ create test.txt this is a line of text for the test file test.txt [Control-Z] The create command creates a file with data entered from the terminal.
- Page 22 Delete the data file: Example $ delete test.txt; $ directory %DIRECT-W-NOFILES, no files found $ type test.txt %TYPE-W-SEARCHFAIL,error searching for $1$DGA100:[USER]TEST.TXT; -RMS-E-FNF, file not found The delete command removes the test.txt file. The directory command verifies that the test.txt file is removed, and the type command verifies that the test.txt file is no longer in the system.

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) - Page 24 Error condition Recommended action The disk array responds “Not Ready” or the disk array has displayed “Not Contact HP. Ready” and timed out. Check the FCA and make sure it was installed properly. Reboot the The host detects a parity error. host.

A 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]). -

- Page 31 Glossary 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).

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.
