252 3ware SATA+SAS RAID Controller Card Software User Guide, Version 10.0
Cause
An error was encountered and the unit is now operating in degraded (non-
redundant) mode. This is usually due to a drive failure or the physical removal
of a drive from a redundant unit.
Action
Check hardware connections and reseat the drive or drives. Rescan the
controller from 3DM 2 or CLI to see if the unit has been restored. If you are
able to restore the unit before any data has been written to the unit, a rebuild
will not be necessary. If the unit remains degraded, replace the missing or
dead drives and initiate a rebuild.
