Displaying a Snapshot copy


The command snapdrive snap show or list displays the name of the storage system where the Snapshot copy is created, the host name, date and time, and so on.

  1. Enter the following command syntax to display a Snapshot copy:

    snapdrive snap show [-snapname] long_snap_name [snap_name…​] [-verbose]

This operation displays, at a minimum, the following information about the Snapshot copy:

  • The name of the storage system where the Snapshot copy is created

  • The name of the host that took the Snapshot copy

  • The path to the LUNs on the storage system

  • The date and time the Snapshot copy was created

  • The name of the Snapshot copy

  • The names of the disk groups included in the Snapshot copy

Example: The following are examples of snapdrive snap show commands:

# snapdrive snap show -snapname toaster:/vol/vol2:snapA snapX snapY

# snapdrive snap show -verbose toaster:/vol/vol2:snapA /vol/vol3:snapB snapC

# snapdrive snap show toaster:/vol/vol2:snapA

# snapdrive snap list -dg dg1 dg2

Example: This example uses a wildcard to display information about the available Snapshot copies on a particular volume:

# snapdrive snap show toaster:/vol/vol1:*
snap name host date
toaster:/vol/vol1:sss1 DBserver Mar 12
16:19 dg1
toaster:/vol/vol1:testdg DBserver Mar 12
15:35 dg1
toaster:/vol/vol1:t1 DBserver Mar 10
18:06 dg1
toaster:/vol/vol1:hp_1 HPserver Mar 8
19:01 vg01
toaster:/vol/vol1:r3 DBserver Mar 8
13:39 rdg1
toaster:/vol/vol1:r1 DBserver Mar 8
13:20 rdg1
toaster:/vol/vol1:snap2 DBserver Mar 8
11:51 rdg1toaster:/vol/vol1:snap_p1 DBserver
Mar 8 10:18 rdg1

Example: In this example, the -verbose option is used in the command line in an AIX host:

# snapdrive snap list betty:/vol/vol1:testsnap -v
snap name host date
betty:/vol/vol1:testsnap aix198-75 Jul 31
10:43 test1_SdDg
host OS: AIX 3 5
snapshot name: testsnap
Volume Manager: aixlvm 5.3
disk group: test1_SdDg
host volume: test1_SdHv
file system: test1_SdHv file system type: jfs2
lun path dev paths
betty:/vol/vol1/aix198-75_luntest1_SdLun /dev/hdisk32

Example: This example includes messages about Snapshot copies on an AIX host that are not created with SnapDrive for UNIX:

# snapdrive snap show -filer toaster
snap name host date
toaster:/vol/vol1:hourly.0 non-snapdrive snapshot
toaster:/vol/vol1:hourly.0 non-snapdrive snapshot
toaster:/vol/vol1:snap1 DBserver1 Oct 01 13:42 dg1
toaster:/vol/vol1:snap2 DBserver2 Oct 10 13:40
toaster:/vol/vol1:snap3 DBserver3 Oct 31 13:45

This example displays a Snapshot copy of an LVM-based file system on an AIX host using the snapdrive snap show command and the - verbose option:

# snapdrive snap show -v -fs /mnt/check_submit/csdg2/hv3_0
snapname host date snapped
toaster:/vol/vol1:mysnapshot sales-aix Aug 24 10:55 csdg2
host OS: AIX 1 5
snapshot name: mysnapshot
Volume Manager: aixlvm 5.1
disk group: csdg2
host volume: csdg2_log
host volume: csdg2_hv3_0
file system: csdg2_hv3_0 file system type: jfs2 mountpoint:
lun path dev paths
spinel:/vol/vol1/check_submit_aix-4 /dev/hdisk4

Example: The following examples use wildcard:

# snapdrive snap show toaster:/vol/volX:*
# snapdrive snap show -v toaster:/vol/volX:DB1*
# snapdrive snap show toaster:/vol/vol2:mysnap* /vol/vol2:yoursnap*
# snapdrive snap show toaster:/vol/volX:*

Example: In this example use of a wildcard is invalid because the wildcard is in the middle of the name instead of being placed at the end:

# snap show toaster:/vol/vol1:my*snap
