Results of a Hard Disk Drive Failure (ServeRAID)



Results of a Hard Disk Drive Failure


Depending on the circumstances, a drive failure can result in several possible situations.

Scenario 1 :


Note: Any logical drives with RAID level 0 are blocked during the Rebuild process, and remain blocked until unblocked. The ServeRAID configuration program autom. unblocks all drives at the end of the rebuild operation.

Scenario 2 :


All data in logical drives assigned RAID level 0 will be lost. In this array, the logical drives that are assigned RAID level 1 or 5 will be in Critical (CRT) state. The logical drives assigned RAID level 0 will be in the Offline (OFL) state.

Sceanario 3 :

If more than one drive in an array fails, all the data is lost in all of the logical drives of the array. For this reason, it is important that you replace and rebuild a defunct drive as soon as possible.
