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

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

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

Perform the steps in this procedure in conjunction with the procedures in the Sun Cluster 3.0 12/01 System Administration Guide and your server hardware manual.

  1. Configure the new StorEdge A5x00 array.

    Note -

    Each 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 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_device command to insert the new array to the cluster and to add paths to its disk drives.


    # luxadm insert_device
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 array to a spare port in the existing hub, switch, or host adapter in your cluster.

    For more information, see the Sun StorEdge A5000 Installation and Service Manual and the Sun StorEdge A5000 Configuration Guide.

    Note -

    Cabling and procedures are different if you are adding StorEdge A5200 arrays in a SAN by using two Sun StorEdge Network FC Switch-8 or Switch-16 switches and Sun SAN Version 3.0 release software. (StorEdge A5000 and A5100 arrays are not supported by the Sun SAN 3.0 release at this time.) See "StorEdge A5200 Array SAN Considerations" for more information.

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

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


    # luxadm probe

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