Sun Cluster Concepts Guide for Solaris OS

Adhering to Quorum Device Requirements

Ensure that Sun Cluster software supports your specific device as a quorum device. If you ignore this requirement, you might compromise your cluster's availability.

Note –

For a list of the specific devices that Sun Cluster software supports as quorum devices, contact your Sun service provider.

Sun Cluster software supports the following types of quorum devices:

Note –

You cannot use a replicated device as a quorum device.

In a two–host configuration, you must configure at least one quorum device to ensure that a single host can continue if the other host fails. See Figure 3–2.

For examples of quorum configurations to avoid, see Bad Quorum Configurations. For examples of recommended quorum configurations, see Recommended Quorum Configurations.
