Your customer using clustered Data ONTAP 8.1.2 recently had a disk drive fail. They already swapped out the failed disk for a replacement disk. They call you the next day explaining that the disk is not showing up in the spare disk pool.
In this scenario, what are two reasons for this problem? (Choose two.)

  • A. The replacement disk drive needs to be manually un-failed before the disk will show up as a spare.
