HP 3PAR OS 3.1.3 Command Line Interface Reference

The following example attempts to recover chunklet 1032:10 of logical disk vv.adm.0, and there
will be output about the progress:
cli% checkld -y -p -recover 1032:10 vv.adm.0
NOTES
Repairing logical disks refers to making logical disks consistent.
Consistency for RAID-1 means that all mirrors in the set have the same data.
Consistency for RAID-5 or RAID-6 means that parity is consistent with the data in the set.
The checkld n command can be issued at any time as it reads only from the logical disk.
If this command is issued for a started logical disk, false negative errors can be reported
because of the contents of the physical disks changing during I/O and the difference in mirror
update time.
The checkld y command can only be issued when the logical disk is in the not started
state.
