Failure in Multiple Logical Drives Simultaneously

If a disk drive fails in more than one logical drive at the same time (one failure per logical drive), and the logical drives have hot spares protecting them, the controller rebuilds the logical drives with these limitations:
  • A hot spare must be of equal or greater size than the failed disk drive it's replacing.
  • Failed disk drives are replaced with hot spares in the order in which they failed. (The logical drive that includes the disk drive that failed first is rebuilt first, assuming an appropriate hot spare is available—see the previous bullet.)
Note: If the number of disk drive failures exceeds the number of hot spares, see Failed Disk Drive Not Protected by a Hot Spare..

If copyback is enabled, data is moved back to its original location once the controller detects that the failed drive has been replaced. See Enabling Copyback for more information.
