Background Information for Defining State Database Replicas

In general, it is best to distribute state database replicas across slices, drives, and controllers, to avoid single points-of-failure. You want a majority of replicas to survive a single component failure. If you lose a replica (for example, due to a device failure), it might cause problems with running Solaris Volume Manager or when rebooting the system. Solaris Volume Manager requires at least half of the replicas to be available to run, but a majority (half plus one) to reboot into multiuser mode.

When you work with state database replicas, consider the following Recommendations for State Database Replicas and Guidelines for State Database Replicas.
