  • Page 7: Installing And Configuring Openvms For The Xp Family Of Disk Arrays

    1 Installing and configuring OpenVMS for the XP family of disk arrays 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

    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. Device emulation types The XP family of disk arrays and the SVS 200 support these device emulation types: OPEN-x devices: OPEN-x logical units represent disk devices.

  • Page 9: Raid Manager Command Devices

    Figure 1 SNMP configuration RAID Manager command devices RAID Manager manages HP StorageWorks XP Business Copy Software or HP StorageWorks XP Continuous Access Software operations from a host server. To use RAID Manager, you must designate at least one LDEV as a command device. For information about how to designate a command device, see the applicable user guide When creating a command device, HP recommends creating a LUN 0 device of 35 megabytes (the smallest allowed).

  • Page 12: Setting The Host Mode For The Disk Array Ports

    If host mode option 33 is not enabled, for all LUNs, determine the device number as follows (once OpenVMS sees the XP disks): OpenVMS device name ($1$dgaxxx), where xxx = CU with LDEV appended (Then convert the created number from hex to decimal) Example For a LUN with a CU of 2 and an LDEV of 59: CU with LDEV appended = 259...

  • Page 13: Setting The Uuid

    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 Setting the UUID HP recommends that OpenVMS customers use host mode option 33 to enable the UUID feature. This increases the capabilities for OpenVMS hosts that access the disk array, by: Allowing the presentation of CU:LDEVs above 7F:FF to the OpenVMS hosts.

  • Page 14: Lun Manager Window

    CAUTION: The UUID (or by default the decimal value of the CU:LDEV value) must be unique across the SAN for the OpenVMS host and/or OpenVMS cluster. No other SAN storage controllers should present the same value. If this value is not unique, data loss will occur. If host mode option 33 is not set, none of the OpenVMS LUNs can have a CU:LDEV value greater than 7F:FF.

  • Page 15: Setting The System Option Modes

    Right-click the selection and then select Set UUID. The Set UUID window will be displayed (see Figure Figure 3 Set UUID window Enter a UUID in UUID in the Set UUID window. When a OpenVMS server host is used, a UUID can consist of the numerical value between 1 to 32,767.

  • Page 16: Fibre Address

    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 (http:// www.hp.com/go/sandesign).

    Figure 4 Multi-cluster environment Within the 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 —...

    Configuring FC switches OpenVMS supports Fibre Channel only in a switched fabric topology. Refer to the switch documentation to set up the switch. 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.

    $ init $1$dga100 testxp Mounting the devices Use the mount command to mount and identify each disk array volume: Example $ mount $1$dga100 testxp 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:...
  • Page 21 Create a test user directory: Example $ create/directory $1$dga100:[user] This command creates a user directory name USER at the top level of the newly added volume $1$DGA100. Change to the new directory: Example $ set default $1$dga100:[user] Verify that this directory exists: Example $ show default $1$dga100:[user]...

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 P9000 or XP Command View Advanced Edition Software (Alerts window) Table 4 Error conditions...

    http://www.hp.com/support/manuals http://www.hp.com/storage/spock Conventions for storage capacity values HP XP storage systems use the following values to calculate physical storage capacity values (hard disk drives): 1 KB (kilobyte) = 1,000 (10 ) bytes 1 MB (megabyte) = 1,000 bytes 1 GB (gigabyte) = 1,000 bytes 1 TB (terabyte) = 1,000 bytes...

    A Disk array supported emulations This appendix provides information about supported emulations and device type specifications. Some parameters might 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]).
