There are a few issues you must consider 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 8 DR feature also apply to Sun Cluster DR support (except for the operating environment quiescence operation). Therefore, review the documentation for the Solaris 8 DR feature before using the DR feature with Sun Cluster software. You should review in particular the issues that affect non-network IO devices during a DR detach operation.
DR remove operations cannot be performed on a device that is currently configured as a quorum device.
If the DR operation would affect an active device, the system 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.
