How to Upgrade StorEdge T3 Disk Tray Firmware

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

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

1. On one node attached to the StorEdge T3 disk tray you are upgrading, detach that StorEdge T3 disk tray'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 StorEdge T3 disk tray 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 StorEdge T3 disk tray, if you have not already done so.

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

4. Reattach the submirrors to resynchronize them.
