Compaq AA-RHGWC-TE manual Example 6-2 Setting Up the Mirrorset, HSG80 RUN Config

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.
