Results of a Hard Disk Drive Failure

Results of a Hard Disk Drive Failure

Depending on the circumstances, there can be several possible results from a drive failure.

Example 1 :

Then the hot spare drive will take over immediately.

NOTE: Hot-spare drive capability does not apply to logical drives assigned RAID level 0. Data for logical drives assigned RAID levels 1 and 5 is maintained, howevwer, system performance will be reduced.

Example 2 :

Then no data will be lost, but the system will operate at reduced performance until the defunct drive is replaced and rebuilt.

Example 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.
