How to Upgrade Sun StorEdge T3 Disk Array Firmware

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

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

1. On one node attached to the Sun StorEdge T3 disk array you want to upgrade, detach that Sun StorEdge T3 disk 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.

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

3. Reset the Sun StorEdge T3 disk array, if you have not already done so.

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

4. Reattach the submirrors to resynchronize them.
