    1 Installing and configuring Solaris 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.

Check with your HP representative for other XP software available for your system. Fibre Channel interface The XP family of disk arrays and the SVS 200 support the following Fibre Channel elements: Connection speeds of 1 Gbps, 2 Gbps, and 4 Gbps.

  • Page 9: Failover

    For detailed information, see “Emulation specifications” on page 31“Disk array device emulations” on page 31. Failover The disk arrays support many standard software products that provide host, application, or I/O path failover and management. The Veritas Cluster Server, Sun Cluster, and Fujitsu Siemens Computers PRIMECLUSTER host failover products are supported for the Solaris operating system.

Note the LUNs and their ports, WWNs, nicknames, and LDEVs for later use in verifying host and device configuration.

  • Page 12: Host Group Modes (Options)

    CAUTION: The correct host mode must be set for all new installations (newly connected ports) to Solaris hosts. Do not select a mode other than 09 for Solaris. Changing a host mode after the host has been connected is disruptive and requires the server to be rebooted. When a new host group is added, additional host group modes (options) may be configured.

    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, see the HP StorageWorks XP24000/XP20000 LUN Manager User Guide applicable to your array.

  • Page 22: Fabric Zoning And Lun Security For Multiple Operating Systems

    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. The nodes share access to the disk array. Figure 3 Multi-cluster environment Within the Storage Area Network (SAN), the clusters may be homogeneous (all the same operating system) or they may be heterogeneous (mixed operating systems).

  • Page 23: Verifying Host Recognition Of Disk Array Devices

    CAUTION: To ensure that the system can boot properly even if you make a mistake in the driver configuration file, add the new paths at the end of the file. (This ensures that the system boot entries higher up in the file will execute first.) Pre-configure additional LUNs (not yet made available) to avoid unnecessary reboots.

  • Page 24: Labeling And Partitioning The Devices

    Labeling and partitioning the devices Partition and label the new devices using the Sun format utility. CAUTION: The repair, analyze, defect, and verify commands/menus are not applicable to the XP arrays and SVS 200. When selecting disk devices, be careful to select the correct disk as using the partition/label commands on disks that have data can cause data loss.

  • Page 25: Creating The Mount Directories

    If you want to create a UFS file system, you can create the file system using the newfs –C maxcontig command to potentially achieve better performance. In most cases, the default maxcontig value on Solaris is 128. maxcontig sets the number of file system blocks read in read-ahead.

With VxVM 4.x versions, you need to download and install the ASL from the Symantec/Veritas support website (http://support.veritas.com): Select Volume Manager for Unix/Linux as product and search the XP array model for Solaris as the platform. Read the TechFile that appears and follow the instructions to download and install the ASL.

    B 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.
