Recovering a RAID Group with an Error Status
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.
Important
RAID recovery only helps when disks are temporarily disconnected and then reconnected.
It does not help in the event of disk failure.
1.
Reconnect all disconnected disks.
Important
Ensure that each disk is reinserted into its original drive bay.
