Dynamic Reconfiguration With Quorum Devices

You must consider a few issues when completing dynamic reconfiguration operations on quorum devices in a cluster.

  • All of the requirements, procedures, and restrictions that are documented for the Oracle Solaris dynamic reconfiguration feature also apply to Oracle Solaris Cluster dynamic reconfiguration support, except for the operating system quiescence operation. Therefore, review the documentation for the Oracle Solaris dynamic reconfiguration feature before using the dynamic reconfiguration feature with Oracle Solaris Cluster software. You should review in particular the issues that affect non-network IO devices during a dynamic reconfiguration detach operation.

  • Oracle Solaris Cluster rejects dynamic reconfiguration remove-board operations that are performed when an interface is present that is configured for a quorum device.

  • If the dynamic reconfiguration operation would pertain to an active device, Oracle Solaris 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.
