How to Upgrade StorEdge T3/T3+ Array Firmware

Use this procedure to upgrade StorEdge T3/T3+ array firmware in a running cluster. StorEdge T3/T3+ array firmware includes controller firmware, unit interconnect card (UIC) firmware, and disk drive firmware.

Perform this procedure on one StorEdge T3/T3+ array at a time. This procedure requires that you reset the StorEdge T3/T3+ array you are upgrading. If you reset more than one StorEdge T3/T3+ array, your cluster will lose access to data if the StorEdge T3/T3+ arrays are submirrors of each other.

1. On one node attached to the StorEdge T3/T3+ array you are upgrading, detach that StorEdge T3/T3+ array's submirrors.

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

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

   See the Sun Cluster 3.0 12/01 Release Notes for information about accessing Sun's EarlyNotifier web pages, which list information about any required patches or firmware levels that are available for download. For the procedure on applying any host adapter firmware patch, see the firmware patch README file.

3. Reset the StorEdge T3/T3+ array, if you have not already done so.

   For the procedure on rebooting a StorEdge T3/T3+ array, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

4. Reattach the submirrors to resynchronize them.

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