001F Unit Operational

272
Action
The drive is now available for use. If the drive is part of a unit add the
remaining drives and rescan the controller, in 3DM or CLI, to bring the unit
online.
Event Type
Error
Cause
The 3ware RAID controller is unable to detect sufficient drives for the unit to
be operable. Some drives have failed or are missing.
Examples of inoperable units are as follows:
• RAID 0 missing any drives.
• A RAID 5 or 50 unit with two or more drives missing from the same
RAID 5 unit or subunits.
• A RAID 10 unit with both drives missing from one of the RAID 1
subunits.
• A RAID 6 unit with three or more drives missing.
The controller only generates this message if the unit is missing drives
Note:
for more than 20 seconds. This allows a hot swap of a drive to be completed
without generating this error.
Action
The unit is no longer available for use. Return all missing drives to the unit. If
the drives are physically present, check all data and power connections.
CAUTION: Do not delete the inoperable unit and recreate it as this will
overwrite the data and make data recovery very difficult.
