You can replace a failed disk drive or a missing disk drive. If you have Solid State Disk (SSD) disk drives, the storage management software will notify you when the disk drive is nearing the end of its life at which time you should schedule to replace the disk drive.
You can replace a failed disk drive with a working disk drive from the list of eligible replacement disk drives that appears on the Replace Disk Drives dialog. Choose a disk drive from the list of eligible replacement disk drives that appears on the Replace Disk Drives dialog. The replacement disk drive must be equal to or greater in size, must have the same speed, and must have the media type and interface type as the failed disk drive or the missing disk drive.
Attention:
Possible loss of data access – Use the Replace Disk Drives option to logically change disk drives. Physically removing and replacing a disk drive might force the array to a Partially Complete status or an Incomplete status.When the Full Disk Encryption (FDE) premium feature is enabled or a disk drive is available, the Security Capable column appears in both the Failed and missing disk drives list and the Available replacement disk drives list. Only security capable disk drives are listed as available replacements for a failed disk drive if that disk drive belongs to a secure array. If the failed disk drive does not belong to a secure array, either a security capable disk drive or a disk drive that is not security capable may be used as a replacement.
