  • Page 7: Installing And Configuring Aix For The P9000 Family Of Disk Arrays

    1 Installing and configuring AIX for the P9000 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

    Device emulation types The P9000 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.

    Figure 1 SNMP configuration RAID Manager command devices HP StorageWorks P9000 RAID Manager Software manages HP StorageWorks P9000 Business Copy Software or HP StorageWorks P9000 Continuous Access Synchronous Software operations from a host server. To use RAID Manager, you must designate at least one LDEV as a command device. This can be done with Remote Web Console Software or P9000 Command View Advanced Edition Suite Software.

  • Page 13: Clustering And Fabric Zoning

    Clustering and fabric zoning If you plan to use clustering, install and configure the clustering software on the servers. Clustering is the organization of multiple servers into groups. Within a cluster, each server is a node. Multiple clusters compose a multi-cluster environment. The following example shows a multi-cluster environment with three clusters, each containing two nodes.

  • Page 14: Connecting The Disk Array

    Connecting the disk array The HP service representative performs the following steps to connect the disk array to the host: 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. Verifying the ready status of the disk array and peripherals.

  • Page 15: Changing The Device Parameters

    Changing the device parameters When the device files are created, the system sets the device parameters to the system default values. You might need to change a few of those values for each new OPEN-x device: For more information, Table 4 Table Read/write (R/W) timeout value Queue depth...
  • Page 16 To change the queue type parameter, enter: chdev –l hdiskx –a q_type='simple' For example, enter the following command to change the queue depth for the device hdisk3: # chdev –l hdisk3 –a queue_depth='2' Verify that the parameters for all devices were successfully changed. For example, enter the following command to verify the parameter change for the device hdisk3: # lsattr –E –l hdisk3 Repeat these steps for each OPEN-x device on the disk array.

    C Using Veritas Cluster Server to prevent data corruption Using VCS I/O fencing By issuing a Persistent Reserve SCSI-3 command, VCS employs an I/O fencing feature that prevents data corruption from occurring if cluster communication stops. To accomplish I/O fencing, each node of VCS registers reserve keys for each disk in a disk group that is imported.
