Information
Cause
The device driver has sent a soft reset to the 3ware RAID controller. The
driver does this when the controller has not responded to a command within
the allowed time limit (30 sec.). After the soft reset command has been sent,
the driver will resend the command.
Action
If this message occurs more than three times a day, collect the system logs and
contact Technical Support.

Event Type
Error
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 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.
