Sun Cluster rejects DR remove-board operations on active drives in the primary node. DR remove-board operations can be performed on inactive drives in the primary node and on any drives in the secondary node. After the DR operation, cluster data access continues as before.
Sun Cluster rejects DR operations that impact the availability of quorum devices. For considerations about quorum devices and the procedure for performing DR operations on them, see SPARC: DR Clustering Considerations for Quorum Devices.
See Dynamic Reconfiguration With Quorum Devices in Sun Cluster System Administration Guide for Solaris OS for detailed instructions about how to perform these actions.
