SPARC: DR Clustering Considerations for Cluster Interconnect Interfaces

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

Caution – Caution –

Sun 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 cluster node.

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