Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS

Complying With Quorum Device Requirements

You must use a quorum device for a two-node cluster. For larger clusters, a quorum device is optional. These are standard cluster requirements.


Note –

On Sun Cluster 3.2 only, a quorum device can be a storage device or a quorum server.


In addition, you can configure quorum devices to ensure that specific rooms can form a cluster in the event of a failure. For guidelines about where to locate your quorum device, see Deciding How to Use Quorum Devices.
