Compaq AA-RHGWB-TE manual Configuring the HSG80 Storagesets

–If the configuration has been saved to disk (with the

INITIALIZE DISKnnnn SAVE_CONFIGURATION or INITIALIZE storageset-nameSAVE_CONFIGURATION option), you can restore it from disk with the CONFIGURATION RESTORE command.

–If you have not saved the configuration to disk, but the label containing the worldwide name and checksum is still intact, or you have recorded the worldwide name and checksum (Section 6.5.3.1) and other configuration information, you can use the command-line interface (CLI) commands to configure the new controller and set the worldwide name. Set the worldwide name as follows:

SET THIS NODEID=nnnn-nnnn-nnnn-nnnn checksum

6.6Preparing to Install Tru64 UNIX and TruCluster Server on Fibre Channel Storage

After the hardware has been installed and configured, there are preliminary steps that must be completed before you install Tru64 UNIX and TruCluster Server on Fibre Channel disks:

•Configure HSG80 storagesets — In this document, example storagesets are configured for both Tru64 UNIX and TruCluster Server on Fibre Channel storage. Modify the storage configuration to meet your needs (Section 6.6.1).

•Set the device unit number — The device unit number is a subset of the device name (as shown in a show device display). For example, in the device name DKA100.1001.0.1.0, the device unit number is 100 (DKA100). The Fibre Channel worldwide name (often referred to as the worldwide ID or WWID) is too long (64 bits) to be used as the device unit number. Therefore, you set a device unit number that is an alias for the Fibre Channel worldwide name (Section 6.6.2).

•Set the bootdef_dev console environment variable — Before you install the operating system (or cluster software), you must set the bootdef_dev console environment variable to ensure that you boot from the right disk (Section 6.6.3).

6.6.1Configuring the HSG80 Storagesets

After the hardware has been installed and configured, storagesets must be configured for software installation. The following disks/disk partitions are needed for base operating system and cluster installation:

•Tru64 UNIX disk

•Cluster root (/)

•Cluster /usr
