You must consider a few issues when completing dynamic reconfiguration (DR) operations on quorum devices in a cluster.
All of the requirements, procedures, and restrictions that are documented for the Solaris DR feature also apply to Sun Cluster DR support, except for the operating system quiescence operation. Therefore, review the documentation for the Solaris DR feature before using the DR feature with Sun Cluster software. You should review in particular the issues that affect nonnetwork IO devices during a DR detach operation.
Sun Cluster rejects DR remove-board operations that are performed when an interface is present that is configured for a quorum device.
If the DR operation would pertain to an active device, Sun Cluster rejects the operation and identifies the devices that would be affected by the operation.
To remove a quorum device, you must complete the following steps, in the order indicated.
