SPARC: Dynamic Reconfiguration Clustering Considerations for Cluster Interconnect Interfaces

If the dynamic reconfiguration remove-board operation pertains to a board containing an active cluster interconnect interface, Oracle Solaris Cluster software rejects the operation. Oracle Solaris Cluster software also identifies the interface that would be affected by the operation. You must use an Oracle Solaris Cluster administrative tool to disable and remove the active interface before the dynamic reconfiguration operation can succeed.

Caution

Caution - Oracle Solaris Cluster software requires each cluster node to have at least one functioning path to every other cluster node. Do not disable a private interconnect interface that supports the last path to any node in the cluster.

See Administering the Cluster Interconnects in Oracle Solaris Cluster System Administration Guide for detailed instructions about how to perform these actions.
