2.Search the display for the UDIDs (or worldwide names) for each of the cluster installation disks and record the /dev/disk/dskn values.

If you used the grep utility to search for a specific UDID, for example hwmgr -view dev grep "IDENTIFIER=131" repeat the command to determine the /dev/disk/dskn for each of the remaining cluster disks. Record the information for use when you install the cluster software.

You must label the disks before you install cluster software.

6.6.4 Label the Disks to Be Used to Create the Cluster

Before you run clu_create to create the first cluster member or

clu_add_member to add subsequent cluster members, you must label the disks to be used for cluster software.

On the system where you installed the Tru64 UNIX operating system, if you have not already done so, boot the system. Determine the /dev/disk/dskn values to use for cluster installation (see Section 6.6.3).

Initialize disklabels for all disks needed to create the cluster. The example (Table 6–2) uses disks dsk18 (/var), dsk19 (/usr), dsk20 [cluster root (/)], and dsk21 (Quorum). For instance:

# disklabel -rw dsk20 HSG80

6.6.5Install the TruCluster Server Software and Create the First Cluster Member

After labeling the disks, use the TruCluster Server Software Installation procedures and install the TruCluster Server software on the first cluster member (the system where you just installed Tru64 UNIX).

After installing the TruCluster Server software subsets, run the clu_create command to create the first cluster member using the procedures in the TruCluster Server Software Installation manual.

When clu_create terminates, do not reboot the system. Shut down the system and reset the bootdef_dev console environment variable to provide multiple boot paths to the member system boot disk before booting (see Section 6.6.6). Then boot the first cluster member.

6.6.6 Reset the bootdef_dev Console Environment Variable

If you set the bootdef_dev console environment variable to multiple paths in Section 6.6.1.5, the base operating system installation or clu_create procedures modify the variable and you should reset it to provide multiple boot paths.
