How to Replace a Failed Disk Drive in a Running Cluster

Use this procedure to replace one failed disk drive in a StorEdge T3+ array that is in your StorEdge 3900 or 6900 Series system, in a running cluster.

If you remove any field replaceable unit (FRU) for an extended period of time, thermal complications might result. To prevent this complication, the StorEdge T3+ array is designed so that an orderly shutdown occurs when you remove a component for longer than 30 minutes. Therefore, a replacement part must be immediately available before starting an FRU replacement procedure. You must replace an FRU within 30 minutes or the StorEdge T3+ array, and all attached StorEdge T3+ arrays, will shut down and power off.

1. Did the failed disk drive impact the array LUN's availability?

   • If not, go to Step 2.

   • If it did impact LUN availability, remove the LUN from volume management control.

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

2. Replace the disk drive in the array.

   For the procedure on replacing a disk drive, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

3. Did you remove a LUN from volume management control in Step 1?

   • If not, you are finished with this procedure.

   • If you did remove a LUN from volume management control, return the LUN to volume management control now.
