9-4 Sun StorEdge 3000 Family Installation, Operation, and Service Manual • May 2004
If there is no local spare drive available, the controller searches for a global spare
drive. If there is a global spare, the controller automatically uses the global spare to
rebuild the logical drive.
Failed Drive Swap Detect. If neither a local spare drive nor a global spare drive is
available, and the “Periodic Auto-Detect Failure Drive Swap Check Time” is
disabled, the controller does not attempt to rebuild unless you apply a forced-
manual rebuild.
To enable the “Periodic Auto-Detect Failure Drive Swap Check Time” feature,
perform the following steps:
1. From the Main Menu, choose “view and edit Configuration parameters → Drive-
side SCSI Parameters → Periodic Auto-Detect Failure Drive Swap Check Time.”
A list of check time intervals is displayed.
2. Select a Periodic Auto-Detect Failure Drive Swap Check Time interval.
A confirmation message is displayed.
3. Choose Yes to confirm.
When the “Periodic Auto-Detect Failure Drive Swap Check Time” is enabled (that is,
when a check time interval has been selected), the controller detects whether the
failed drive has been replaced by checking the failed drive's channel/ID. Once the
failed drive has been replaced, the rebuild begins immediately.
Note – This feature requires system resources and can impact performance.
If the failed drive is not replaced but a local spare is added to the logical drive, the
rebuild begins with the spare.
