RAID recovery enables you to recover a RAID group in the event of accidental disk removal or SATA connector failure. When several disks are removed or disconnected from a RAID group:
The status of the group changes to Error.
The statuses of all volumes and storage pools using the RAID group change to Inactive.
All data on the affected volumes and LUNs becomes inaccessible.
RAID recovery only helps when disks are temporarily disconnected and then reconnected. It does not help in the event of disk failure.
QTS starts to rebuild the RAID group.
