How to Replace Host Adapters

This section contains the procedure for replacing a failed host adapter in a node in a running cluster. For conceptual information on host adapters, see the Sun Cluster 3.0 12/01 Concepts document.

You must maintain at least one cluster interconnect between the nodes of a cluster. The cluster does not function without a working cluster interconnect. You can check the status of the interconnect with the command, scstat -W. For more details on checking the status of the cluster interconnect, see the Sun Cluster 3.0 12/01 System Administration Guide.

1. Shut down the node with the host adapter you want to replace.

   # 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.

2. Power off the node.

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

3. Disconnect the transport cable from the host adapter and other devices.

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

4. Replace the host adapter.

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

5. Reconnect the transport cable to the new host adapter.

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

6. Power on and 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.

Where to Go From Here

When you are finished replacing all of your interconnect hardware, if you want to reconfigure Sun Cluster with the new interconnect components, see the Sun Cluster 3.0 12/01 System Administration Guide for instructions on administering the cluster interconnect.
