snapmirror initialize-ls-set

Start a baseline load-sharing set transfer

Availability: This command is available to cluster and Vserver administrators at the admin privilege level.

Description​

The snapmirror initialize-ls-set command initializes and updates a set of load-sharing mirrors. This command is usually used after the snapmirror create command is used to create a SnapMirror relationship for each of the destination volumes in the set of load-sharing mirrors. The initial transfers to empty load-sharing mirrors are baseline transfers done in parallel. During a baseline transfer Data ONTAP takes a Snapshot copy on the source volume to capture the current image of the source volume and transfers all of the Snapshot copies on the source volume to each of the destination volumes.

After the snapmirror initialize-ls-set command successfully completes, the last Snapshot copy transferred is made the exported Snapshot copy on the destination volumes.

The parameter that identifies the set of load-sharing mirrors is the source volume. Data and Snapshot copies are transferred from the source volume to all up-to-date destination volumes in the set of load-sharing mirrors.

Use the snapmirror initialize command to add and initialize a new destination volume to an existing set of load-sharing mirrors.
Note
Even if the load-sharing set only has one mirror, you still need to use the snapmirror initialize-ls-set command to initialize the set. The snapmirror initialize command can only be used to initialize a new destination volume, if the load-sharing set has already been initialized.

This command is only supported for SnapMirror relationships with the field "Relationship Capability" showing as "Pre 8.2" in the output of the snapmirror show command.

Parameters​

{ -source-path | -S {<[vserver:][volume]>|<[[cluster:]//vserver/]volume>|<hostip:/lun/name>|<hostip:/share/share-name>|<[vserver:]/cg/[cgname]>} - Source Path
This parameter specifies the source endpoint of the SnapMirror relationship in one of four path formats. The normal format includes the names of the Vserver (vserver) and/or the volume (volume).
-source-vserver <vserver name> - Source Vserver
Specifies the source Vserver of the SnapMirror relationship. This parameter is not supported for relationships with non-Data ONTAP source endpoints.
-source-volume <volume name>} - Source Volume
Specifies the source volume of the SnapMirror relationship. This parameter is not supported for relationships with non-Data ONTAP source endpoints.

Examples​

To initialize the group of load-sharing mirrors for the source endpoint //vs1.example.com/dept_eng, type the following command:

cluster1::> snapmirror initialize-ls-set -source-path
       //vs1.example.com/dept_eng
