Displaying instant snapshot information
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 --
snapvol1vol1_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 ]
