Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

This command shows the percentage progress of the synchronization of a snapshot
or volume. If no volume is specified, information about the snapshots for all the
volumes in a disk group is displayed. The following example shows a volume,
vol1, which has a full-sized snapshot, snapvol1 whose contents have not been
synchronized with vol1:
# vxsnap -g mydg print
NAME SNAPOBJECT TYPE PARENT SNAPSHOT %DIRTY %VALID
vol1 -- volume -- -- -- 100
snapvol1_snp1 volume -- snapvol1 1.30 --
snapvol1 vol1_snp1 volume vol1 -- 1.30 1.30
The %DIRTY value for snapvol1 shows that its contents have changed by 1.30%
when compared with the contents of vol1. As snapvol1 has not been synchronized
with vol1, the %VALID value is the same as the %DIRTY value. If the snapshot were
partly synchronized, the %VALID value would lie between the %DIRTY value and
100%. If the snapshot were fully synchronized, the %VALID value would be 100%.
The snapshot could then be made independent or moved into another disk group.
Additional information about the snapshots of volumes and volume sets can be
obtained by using the -n option with the vxsnap print command:
# vxsnap [-g diskgroup] -n [-l] [-v] [-x] print [vol]
Alternatively, you can use the vxsnap list command, which is an alias for the
vxsnap -n print command:
# vxsnap [-g diskgroup] [-l] [-v] [-x] list [vol]
The following output is an example of using this command on the disk group dg1:
# vxsnap -g dg -vx list
