EXAMPLES
The following example displays a validity check of logical disk vv63.admn.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.
cli% checkld –n vv63.adm.0
