Sun Cluster rejects dynamic reconfiguration (DR) remove-board operations on active drives on the primary host. You can perform DR remove-board operations on inactive drives on the primary host and on any drives in the secondary host. 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.
