  • Page 7: Installing And Configuring Tru64 For The Xp Disk Array

    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.

  • Page 8: Device Emulation Types

    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.

    http://www.hp.com/support/manuals. 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.

  • Page 10: Installing And Configuring The Disk Array

    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.

  • Page 11: Setting The Host Mode And Host Group Mode For The Disk Array Ports

    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.

  • Page 12: Setting The System Option Modes

    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.

  • Page 13: 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 available at: http://www.hp.com/go/sandesign.

  • Page 15: Configuring System Files

    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.

  • Page 16: Connecting The Disk Array

    • 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.

  • Page 17: Verifying Host Recognition Of Disk Array Devices

    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.

  • Page 18: Writing The Partition Labels

    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.

  • Page 19: Creating Mount Directories

    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.

  • Page 20: Mounting An Advanced File System

    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.

  • Page 33: 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 34 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).
