Sun Cluster 3.0-3.1 With Sun StorEdge T3 or T3+ Array Manual for Solaris OS

ProcedureHow to Upgrade Storage Array Firmware When Using Mirroring

Use this procedure to upgrade out-of-date controller firmware, disk drive firmware, or unit interconnect card (UIC) firmware. This procedure assumes that your cluster is operational. This procedures defines Node A as the node on which you are upgrading firmware. Node B is another node in the cluster.


Caution – Caution –

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


Steps
  1. On the node that currently owns the disk group or diskset to which the mirror belongs, detach the storage array logical volume. This storage array is the storage array on which you are upgrading firmware.

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

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

    For the list of required storage array patches, see the Sun StorEdge T3 Disk Tray Release Notes. For the procedure about how to apply firmware patches, see the firmware patch README file. For the procedure about how to verify the firmware level, see the Sun StorEdge T3 Disk Tray Release Notes.

  3. Disable the storage array controller that is attached to Node B. Disable the controller so that all logical volumes are managed by the remaining controller.

    For more information, see the Sun StorEdge T3 and T3+ Array Administrator's Guide.

  4. On one node that is connected to the partner group, verify that the storage array controllers are visible to the node.

  5. Enable the storage array controller that you disabled in Step 3.

  6. Reattach the mirrors that you detached in Step 1 to resynchronize the mirrors.
