HP Array Controller HSG V8.7 Software - Manual (Page 313)

CLI Commands B–41
CLEAR_ERRORS unit-number LOST_DATA
Clears lost data errors on a unit; 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
The following command will clear the lost data error on disk unit
number D103:
CLEAR_ERRORS D103 LOST_DATA
