How to Replace a Host Adapter in a Node (Connected to a StorEdge A3500FC System)

This section describes the procedure for replacing a failed host adapter in a node that is attached to a StorEdge A3500FC fiber-optic-based system. For the same procedure for a cluster node that is attached to a StorEdge A3500 system, see "How to Replace a Host Adapter in a Node (Connected to a StorEdge A3500 System)".

Several steps in this procedure require that you halt I/O activity. To halt I/O activity, take the controller module offline by using the RAID Manager GUI's manual recovery procedure in the Sun StorEdge RAID Manager User's Guide.

1. Move all Sun Cluster data services off of the node in which you are replacing a host adapter.

   See the Sun Cluster 3.0 U1 Data Services Installation and Configuration Guide for instructions.

2. Halt all I/O activity on the affected StorEdge A3500FC controller module.

   See the Sun StorEdge RAID Manager User's Guide for instructions.

3. Shut down and power off the node in which you are replacing a host adapter.

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

   For the procedure on shutting down and powering off a node, see the Sun Cluster 3.0 U1 System Administration Guide.

4. Disconnect the fiber-optic cable from the host adapter that you are replacing.

5. Replace the host adapter in the node.

   See the documentation that came with your node hardware for instructions.

6. Connect the fiber optic cable to the new host adapter that you just installed.

7. Boot the node into cluster mode.

   {0} ok boot

8. Restart I/O activity on the affected StorEdge A3500FC controller module.

   See the Sun StorEdge RAID Manager User's Guide and your operating system documentation for instructions.

9. Check the status of the affected StorEdge A3500FC controller module.

   Observe the front panel LEDs and interpret them by using the Sun StorEdge A3500/A3500FController Module Guide.

10. Rebalance LUNs that are running on the affected StorEdge A3500FC controller module.

    For more information, see the Sun StorEdge RAID Manager User's Guide.

11. Move the Sun Cluster data services back to the node in which you replaced the host adapter.

    See the Sun Cluster 3.0 U1 Data Services Installation and Configuration Guide for instructions.
