Use the following procedure to remove cluster transport cables, transport adapters, and transport switches from a node configuration. When a cable is disabled, the two endpoints of the cable remain configured. An adapter cannot be removed if it is still in use as an endpoint on a transport cable.
Caution - Each cluster node needs at least one functioning transport path to every other node in the cluster. No two nodes should be isolated from one another. Always verify the status of a node's cluster interconnect before disabling a cable. Only disable a cable connection after you have verified that it is redundant. That is, ensure that another connection is available. Disabling a node's last remaining working cable takes the node out of cluster membership. |
The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global cluster.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.
You can also use the Oracle Solaris Cluster Manager GUI to remove cables, transport adapters, and private adapters from your cluster. For GUI log-in instructions, see How to Access Oracle Solaris Cluster Manager.
# clinterconnect status
Caution - If you receive an error such as “path faulted” while attempting to remove one node of a two-node cluster, investigate the problem before continuing with this procedure. Such a problem could indicate that a node path is unavailable. Removing the remaining operational path takes the node out of cluster membership and could result in a cluster reconfiguration. |

The transport cable or adapter removed from the respective node should not appear in the output from this command.
The following example shows how to remove a transport cable, transport adapter, or transport switch by using the clsetup command.
