The drive properties are DEVICE TYPE (DISK), CAPACITY, PRODUCT ID, and REVISION NO. These properties are view-only.

4-8 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.
