Oracle Solaris Cluster rejects dynamic reconfiguration remove-board operations on active drives on the primary node. You can perform dynamic reconfiguration remove-board operations on inactive drives on the primary node and on any drives in the secondary node. After the dynamic reconfiguration operation, cluster data access continues as before.
See Dynamic Reconfiguration With Quorum Devices in Oracle Solaris Cluster System Administration Guide for detailed instructions about how to perform these actions.
