When you run the snap list command, you can distinguish SnapMirror Snapshot copies from the regular system Snapshot copies by their naming conventions.
For volume replication,
SnapMirror creates a
Snapshot copy of the entire source volume that is copied to the destination volume.
A SnapMirror volume Snapshot copy name is in the following format.
dest_system(sysid)_name.number- dest_system is the host name of the destination system.
- sysid is the destination system ID number.
- name is the name of the destination volume.
- number is the number of successful transfers for the Snapshot copy, starting at 1. Data ONTAP increments this number for each transfer.
Note: In the output of the
snap list command,
SnapMirror Snapshot copies are followed by the
SnapMirror name in parentheses.
Volume example
systemA(0016791363)_vol0.9 (snapmirror)
For qtree replication, SnapMirror creates Snapshot copies of one or more source qtrees on the source volume that are copied to a qtree on the destination volume.
A SnapMirror qtree Snapshot copy name is in the following format.
dest_system(sysid)_name-src|dst.number- dest_system is the host name of the destination system.
- sysid is the destination system ID number.
- name is the name of the destination volume or qtree path.
- src|dst is the source or destination name.
- number is an arbitrary start point number for the Snapshot copy. Data ONTAP increments this number for each transfer.
Qtree example
systemA(0016789302)_vol1_qtree3-dst.15 (snapmirror)
Note: Do not delete manually created Snapshot copies marked “snapmirror” in the output of the snap list command.
