How to Add a StorEdge A5x00 Disk Array to a Running Cluster That Has Existing StorEdge A5x00 Disk Arrays

Use this procedure to install a StorEdge A5x00 disk array in a running cluster that already has StorEdge A5x00 disk arrays installed and configured with hubs.

If you are installing the first StorEdge A5x00 disk array to a running cluster that does not yet have a StorEdge A5x00 disk array installed, use the procedure in "How to Add the First StorEdge A5x00 Disk Array to a Running Cluster".

Perform the steps in this procedure in conjunction with the procedures in the Sun Cluster 3.0 U1 System Administration Guide and your server hardware manual.

  1. Configure the new StorEdge A5x00 disk array.

    Note -

    Each disk array in the loop must have a unique box ID. If necessary, use the front-panel module (FPM) to change the box ID for the new StorEdge A5x00 disk array you are adding. For more information about StorEdge A5x00 loops and general configuration, see the Sun StorEdge A5000 Configuration Guide and the Sun StorEdge A5000 Installation and Service Manual.

  2. On both nodes, use the luxadm insert command to insert the new disk array to the cluster and to add paths to its disk drives.


    # luxadm insert
Please hit <RETURN> when you have finished adding
Fibre Channel Enclosure(s)/Device(s):

    Note -

    Do not press Return until after you have completed Step 3.

  3. Cable the new StorEdge A5x00 disk array to a spare port in the existing hub or host adapter in your cluster.

    For cabling instructions and diagrams, see the Sun StorEdge A5000 Configuration Guide.

  4. After you have finished cabling the new disk array, press Return to complete the luxadm insert operation (sample output shown below).

  5. On both nodes, use the luxadm probe command to verify that the new StorEdge A5x00 disk array is recognized by both cluster nodes.


    # luxadm probe

  6. On one node, use the scgdevs command to update the DID database.
