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

ProcedureHow to Upgrade Storage Array Firmware (No Submirrors)

Use this procedure to upgrade storage array firmware in a running cluster, when your arrays are not configured to support submirrors. To upgrade firmware when you are using submirrors, see How to Upgrade Storage Array Firmware When Using Mirroring. Firmware includes controller firmware, unit interconnect card (UIC) firmware, and disk drive firmware.

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.

Note –

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

Steps

  1. On one node that is attached to the storage array, detach the submirrors. This storage array is the storage array that you are upgrading.

    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.

    PatchPro is a patch-management tool that eases the selection and download of patches required for installation or maintenance of Sun Cluster software.

PatchPro's Expert Mode tool helps you to maintain your configuration with the latest set of patches. Expert Mode is especially useful for obtaining all of the latest patches, not just the high availability and security patches.

    To access the PatchPro tool for Sun Cluster software, go to http://www.sun.com/PatchPro/, click Sun Cluster, then choose either Interactive Mode or Expert Mode. Follow the instructions in the PatchPro tool to describe your cluster configuration and download the patches.

    For third-party firmware patches, see the SunSolveSM Online site at http://sunsolve.ebay.sun.com.

  3. Reset the storage array, if you have not already done so.

    For the procedure about how to reboot a storage array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

  4. Reattach the submirrors to resynchronize the submirrors.
