If the dynamic reconfiguration remove-board operation pertains to a board that contains an interface to a device configured for quorum, Oracle Solaris Cluster software rejects the operation. Oracle Solaris Cluster software also identifies the quorum device that would be affected by the operation. You must disable the device as a quorum device before you can perform a dynamic reconfiguration remove-board operation.
See Chapter 6, Administering Quorum, in Oracle Solaris Cluster System Administration Guide for detailed instructions about how administer quorum.
