Expansion unit recovery
If an expansion unit is accidentally disconnected from the NAS, for example by an unscheduled shutdown or disconnected cable, then the following changes to storage state will occur:
-
The status of all storage pools on the expansion unit will change to Error.
-
The status of all RAID groups on the expansion unit will change to Not Active.
If you encounter this situation, reconnect the expansion unit to the NAS and QuTS hero will automatically guide you through the recovery process.
