How to Remove Transport Cables and Transport Junctions

This section contains the procedure for removing an unused transport cable or transport junction (switch) from a node in a running cluster.

You must maintain at least one cluster interconnect between the nodes of a cluster. The cluster does not function without a working cluster interconnect.

1. Check to see whether the transport cable and/or transport junction (switch) you want to replace appears in the Sun Cluster software configuration.

   • If the interconnect component you want to remove appears in the Sun Cluster software configuration, remove the interconnect component from the Sun Cluster configuration. To remove an interconnect component, follow the interconnect administration procedures in the Sun Cluster 3.0 System Administration Guide before going to Step 2.

   • If the interconnect component you want to remove does not appear in the Sun Cluster software configuration, go to Step 2.

2. Shut down the node that is connected to the transport cable and/or transport junction (switch) you are removing.

   # scswitch -S -h nodename # shutdown -y -g0 -i0

   For the procedure on shutting down a node, see the Sun Cluster 3.0 12/01 System Administration Guide.

3. Disconnect the transport cables and/or transport junction (switch) from the other cluster devices.

   For the procedure on disconnecting cables from host adapters, see the documentation that shipped with your host adapter and node.

4. Boot the node.

   # boot -r

   For the procedures on powering on and booting a node, see the Sun Cluster 3.0 12/01 System Administration Guide.
