3.8 Forcing Drives Online or Offline
The MegaRAID BIOS CU enables you to force drives online or offline.
You may want to force a drive of a redundant array offline so that a
hotspare drive will automatically replace it. An auto rebuild will begin
immediately if the MegaRAID BIOS CU finds a valid hotspare drive to
replace the offline drive.
You may need to force a drive online if it has gone offline due to a power
failure. The MegaRAID BIOS CU will not allow a drive to be forced online
if its size is smaller than the defined size of the array.
To force a drive online or offline, follow these steps:
1. On the Management Menu, select Objects → Physical Drive.
2. Highlight a physical drive that is a member of an array and press
Enter.
