Displaying Instant Snapshot Information (vxsnap print)
The vxsnap print command may be used to display information about the snapshots
that are associated with a volume.
# vxsnap [-g diskgroup] print [vol]
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.
