Removing Cluster Transport Adapters

This section provides the procedure for removing cluster transport adapters.

For conceptual information on cluster transport adapters, see Sun Cluster 3.0 Concepts.

How to Remove Cluster Transport Adapters

Caution - Caution -

You must maintain at least one cluster interconnect between the nodes of a cluster. The cluster will not function properly without a functioning cluster interconnect.

  1. Verify that the cluster transport adapter you want to replace appears in the Sun Cluster software configuration.

    • If the cluster transport adapter you want to replace appears in the Sun Cluster software configuration, remove the cluster transport adapter from the Sun Cluster configuration. To remove a cluster interconnect, see the Sun Cluster 3.0 System Administration Guide, then proceed to Step 2.

    • If the cluster transport adapter you want to replace does not appear in the Sun Cluster software configuration, proceed to Step 2.

  2. Disconnect any cluster interconnect connections cabled to the cluster transport adapter.

    This procedure is the same procedure in a non-cluster environment. For the procedure on disconnecting network connections from cluster transport adapters, see the documentation that shipped with your network adapter.

  3. Shut down the node with the cluster transport adapter you want to remove.


    # scswitch -S -h nodename
# shutdown -y -g 0

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

  4. Power off the node.

    For the procedure on powering off a node, see the documentation that shipped with your node.

  5. Disconnect the cluster transport cables from the cluster transport adapter and other devices.

    This procedure is the same in a non-cluster environment. For the procedure on disconnecting cables from cluster transport adapters, see the documentation that shipped with your network adapter and node.

  6. Remove the cluster transport adapter.

    This procedure is the same in a non-cluster environment. For the procedure on removing cluster transport adapters, see the documentation that shipped with your network adapter and node.

  7. Power on and boot the node.

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