Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

SPARC: Replicating Solaris Volume Manager Disksets

If you use Solstice DiskSuite/Solaris Volume Manager as your volume manager for shared device groups, carefully plan the distribution of your replicas. In two-room configurations, all disksets should be configured with an additional replica in the room that houses the cluster quorum device. For example, in three-room two-node configurations, a single room houses both the quorum device and at least one extra disk configured into each of the disksets. Each diskset should have extra replicas in the third room.

Note –

You can use a quorum disk for these replicas.

Refer to your Solstice DiskSuite/Solaris Volume Manager documentation for details on configuring diskset replicas.
