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-MIR mirrorset, 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.
