Compaq AA-RHGWB-TE manual Example 6-2 Setting up the Mirrorset, HSG80 RUN Config

•Cluster /var

•Member boot disk (one for each cluster member system)

•Quorum disk (if used)

If you are installing only the operating system, you need only the Tru64 UNIX disk (and of course any disks for applications). This document assumes that both the base operating system and cluster software are to be installed on Fibre Channel disks.

If you are installing a cluster, you need one or more disks to hold the Tru64 UNIX operating system. The disk(s) are either private disk(s) on the system that will become the first cluster member, or disk(s) on a shared bus that the system can access. Whether the Tru64 UNIX disk is on a private disk or a shared disk, you should shut down the cluster before booting a cluster member system standalone from the Tru64 UNIX disk.

An example configuration will show the procedure necessary to set up disks for base operating system and cluster installation. Modify the procedure according to your own disk needs. You can use any supported RAID level.

The example will be based on the use of four 4-GB disks used to create two mirrorsets (RAID level 1) to provide reliability. The mirrorsets will be partitioned to provide partitions of appropriate sizes. Disks 30200, 30300, 40000, and 40100 will be used for the mirrorsets.

Table 6–2 contains the necessary information to convert from the HSG80 unit numbers to /dev/disk/dskn and device names for the example configuration. A blank table (Table A–1) is provided in Appendix A for use in an actual installation.

One mirrorset, the BOOT-MIRmirrorset will be used for the Tru64 UNIX and cluster member system boot disks. The other mirrorset, CROOT-MIR, will be used for the cluster root (/), cluster /usr, cluster /var, and quorum disks.

To set up the example disks for operating system and cluster installation, follow the steps in Example 6–2.
