Sun StorEdge T3/T3+ Single-Controller Configuration (5/02)

The Sun Cluster 3.0 12/01 Hardware Guide chapter "Installing and Maintaining a Sun StorEdge T3 or T3+ Array Single-Controller Configuration" incorrectly indicates that the procedure for upgrading a Sun StorEdge T3 array controller to a Sun StorEdge T3+ array controller does not require any cluster-specific steps. The correct procedure should be as follows.

How To Upgrade a StorEdge T3 Controller to a StorEdge T3+ Controller (5/02)

Perform this procedure on one array at a time. This procedure requires that you take the array in which you are upgrading the controller offline. If you take more than one array offline, your cluster will lose access to data, if the arrays are submirrors of each other.

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

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

2. Upgrade the StorEdge T3 array controller to a StorEdge T3+ array controller.

   See the Sun StorEdge T3 Array Controller Upgrade Manual for instructions.

3. Reattach the submirrors to resynchronize them.

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