How to Replace a SCSI Cable

Use this procedure to replace a failed SCSI cable in a running cluster.

Steps

1. Is one of the disks in the storage array a quorum device? This array is the array that is attached to the cable you are replacing.

   # scstat -q

   • If no, proceed to Step 2.

   • If yes, relocate that quorum device to another suitable storage array

     For procedures about how to add and remove quorum devices, see the Sun Cluster system administration documentation.

2. Detach the submirror or submirrors on the storage array.

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

3. Replace the SCSI cable.

4. Reattach the submirror or submirrors on the storage array.

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

5. (Optional) Did you relocate the quorum device in Step 1?

   • If no, this step completes the procedure.

   • If yes, relocate the quorum device function to this storage array.

     For procedures about how to add and remove quorum devices, see the Sun Cluster system administration documentation.
