PDFs
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.
-
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 snapped ------------------------------------------------------------------ ------------- 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 snapped ------------------------------------------------------------------ ------------- 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 mountpoint: /mnt/test1 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 snapped ------------------------------------------------------------------ ------------- 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 dg2 toaster:/vol/vol1:snap2 DBserver2 Oct 10 13:40 DBdg/hvol1 toaster:/vol/vol1:snap3 DBserver3 Oct 31 13:45 DBdg
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: /mnt/check_submit/csdg2/hv3_0 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* filer1:/vol/volY:DB2* # snapdrive snap show toaster:/vol/vol2:mysnap* /vol/vol2:yoursnap* hersnap* # 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
