Solstice DiskSuite 4.2.1 Reference Guide

State Database Replicas

Note -

Replicas cannot be stored on the root (/), swap, or /usr slices, or on slices containing existing file systems or data.

Summary of State Database Replicas

Note -

If you created two replicas on each disk in a two-disk configuration, DiskSuite will still function if one disk fails. But because you must have one more than half of the total replicas available in order for the system to reboot, you will be unable to reboot in this state.
