Compaq AA-RHGWB-TE 6.6 Preparing to Install Tru64 UNIX and TruCluster Server on Fibre Channel Storage

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

INITIALIZE DISKnnnn SAVE_CONFIGURATION or INITIALIZE

storageset-name SAVE_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

6.6 Preparing to Install Tru64 UNIX and TruCluster Serveron 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 asthe 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).

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
