How to Upgrade StorEdge T3+ Array Firmware

Use one of the following procedures to upgrade the firmware on the StorEdge T3+ arrays in your StorEdge 3900 or 6900 Series system, depending on whether your array partner-group has been configured to support submirrors of a cluster node's volumes. StorEdge T3+ array firmware includes controller firmware, unit interconnect card (UIC) firmware, EPROM firmware, and disk drive firmware.

Note -

For all firmware, always read any README files that accompany the firmware for the latest information and special notes.

Upgrading Firmware on Arrays That Support Submirrored Data

Caution - Caution -

Perform this procedure on one array at a time. This procedure requires that you reset the arrays you are upgrading. If you reset more than one array at a time, your cluster will lose access to data.

  1. On the node that currently owns the disk group or disk set to which the submirror belongs, detach the submirrors of the array on which you are upgrading firmware. (This procedure refers to this node as Node A and remaining node as Node B.)

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

  2. Disconnect both array-to-switch fiber optic cables from the two arrays of the partner-group.

  3. Apply the controller, disk drive, and UIC firmware patches.

    For the list of required StorEdge T3+ array patches, see the Sun StorEdge T3 Disk Tray Release Notes. For the procedure on applying firmware patches, see the firmware patch README file. For the procedure on verifying the firmware level, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  4. Reset the arrays.

    For the procedure on resetting an array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  5. Use the StorEdge T3+ disable command to disable the array controller that is attached to Node B so that all logical volumes come under the control of the remaining controller.


    t3:/:<#> disable uencidctr

    See the Sun StorEdge T3 and T3+ Array Administrator's Guide for more information about the disable command.

  6. Reconnect both array-to-switch fiber optic cables to the two arrays of the partner-group.

  7. On one node connected to the partner-group, use the format command to verify that the array controllers are rediscovered by the node.


    # format

  8. Use the StorEdge T3+ enable command to enable the array controller that you disabled in Step 5.


    t3:/:<#> enable uencidctr

  9. Reattach the submirrors that you detached in Step 1 to resynchronize them.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

Upgrading Firmware on Arrays That Do Not Support Submirrored Data

In a partner-pair configuration, it is possible to have non-mirrored data; however, this requires that you shutdown the cluster when upgrading firmware, as described in this procedure.

  1. Shutdown the entire cluster.


    # scshutdown -y -g0

    For the full procedure on shutting down a cluster, see the Sun Cluster 3.0 12/01 System Administration Guide.

  2. Apply the controller, disk drive, and UIC firmware patches.

    For the list of required StorEdge T3+ array patches, see the Sun StorEdge T3 Disk Tray Release Notes. For the procedure on applying firmware patches, see the firmware patch README file. For the procedure on verifying the firmware level, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  3. Reset the arrays.

    For the procedure on resetting an array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  4. Boot all nodes back into the cluster.


    ok boot

    For the full procedure on booting nodes into the cluster, see the Sun Cluster 3.0 12/01 System Administration Guide.

  5. On one node connected to the partner-group, use the format command to verify that the array controllers are rediscovered by the node.
