CLEAR_ERRORS
unit-number
LOST_DATA
Clears lost data errors on a unit and all partitions on the unit’s container are affected.
The controller reports a lost data error on the unit when you remove a write-back
cache module or when the cache module contains unflushed data, possibly due to an
interruption in the primary power source with no backup power present. The
CLEAR_ERRORS LOST_DATA command clears the lost data error but does not
recover the lost data.
NOTE: Clearing lost data errors or lost data block errors on a RAIDset causes a
reconstruction of all parity blocks. Clearing lost data errors or lost data block errors
on a mirrorset causes members to normalize.
Syntax
CLEAR_ERRORS unit-number LOST_DATA
Spell out LOST_DATA when using this command.
CAUTION: This command may cause data loss.
Parameters
unit-number
Identifies the unit on which the lost data error is to be cleared. The unit-number is the
same name given to the unit when you added it to the controller’s configuration.
Example
