Naming conventions for Snapshot copies used by SnapMirror

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 qtree SnapMirror 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)
Attention: You should not delete manually-created Snapshot copies marked snapmirror in the output of the snap list command. Otherwise, later SnapMirror updates might fail.
