DR Clustering Considerations for Private Interconnect Interfaces

DR operations cannot be performed on active private interconnect interfaces. If the DR remove-board operation would affect an active private interconnect interface, the system rejects the operation and identifies the interface that would be affected by the operation. An active interface must first be disabled before you remove it (also see the caution below). When an interface is replaced to the private interconnect, its state remains the same, avoiding any need for additional Sun Cluster reconfiguration steps.

The following steps describe a brief summary of the procedure for performing a DR remove operation on a private interconnect interface. See the Sun Cluster 3.0 U1 System Administration Guide for detailed instructions on how to perform these actions.

Sun Cluster requires that each cluster node has 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.

1. Disable the transport cable that contains the interconnect interface upon which you are performing the DR operation.

2. Perform the DR remove operation on the physical private interconnect interface.
