Effects of a disk drive failure
When a disk drive fails, all virtual disks that are in the same array are affected. Each virtual disk
in an array might be using a different fault-tolerance method, so each can be affected differently.
•
RAID0 configurations cannot tolerate drive failure. If any physical drive in the array fails, all
non-fault-tolerant (RAID0) logical drives in the same disk group also fail.
•
RAID1+0 configurations can tolerate multiple drive failures as long as no failed drives are
mirrored to one another (with no spares assigned).
•
RAID5 configurations can tolerate one drive failure (with no spares assigned).
•
RAID6 configurations can tolerate simultaneous failure of two drives (with no spares assigned).
Compromised fault tolerance
If more disk drives fail than the fault-tolerance method allows, fault tolerance is compromised, and
the virtual disk fails.
Factors to consider before replacing disk drives
Before replacing a degraded drive:
•
Be sure that the array has a current, valid backup.
•
Use replacement drives that have a capacity at least as great as that of the smallest drive in
the array. The controller immediately fails drives that have insufficient capacity.
