snapmirror update-ls-set

Start an incremental load-sharing set transfer

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

Description

The snapmirror update-ls-set command updates a set of load-sharing mirrors. The command makes destination volumes, in the group of load-sharing mirrors, up-to-date mirrors of the source volume.

The key parameter that identifies the set of load-sharing mirrors is the source volume. SnapMirror transfers are performed from the source volume to each of the up-to-date destination volumes in the set of load-sharing mirrors.

The snapmirror update-ls-set command performs an incremental transfer to each of the destination volumes. During an incremental transfer, Data ONTAP takes a Snapshot copy on the source volume to capture the current image of the source volume, finds the most recent common Snapshot copy between the source and destination volumes, and incrementally transfers Snapshot copies that are newer than the common Snapshot copy to the destination volume.

Note:

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

This command is not supported on Infinite Volume snapmirror relationships.

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>} - Source Path

Specifies the source endpoint of the SnapMirror relationship in one of two path formats. The normal format includes the names of the Vserver (vserver) and volume (volume). To support relationships with "Relationship Capability" of "Pre 8.2", a format which also includes the name of the cluster (cluster) is provided. The "Pre 8.2" format cannot be used when operating in a Vserver context on relationships with "Relationship Capability" of "8.2 and above".

|  [-source-cluster <Cluster name>] - Source Cluster

Specifies the source cluster of the SnapMirror relationship. If this parameter is specified, the -source-vserver and -source-volume parameters must also be specified. This parameter is only applicable for relationships with "Relationship Capability" of "Pre 8.2". This parameter cannot be specified when operating in a Vserver context on relationships with "Relationship Capability" of "8.2 and above".

   -source-vserver <vserver name> - Source Vserver

Specifies the source Vserver of the SnapMirror relationship. If this parameter is specified, parameters -source-volume and for relationships with "Relationship Capability" of "Pre 8.2", -source-cluster must also be specified.

   -source-volume <volume name>  } - Source Volume

Specifies the source volume of the SnapMirror relationship. If this parameter is specified, parameters -source-vserver and for relationships with "Relationship Capability" of "Pre 8.2", -source-cluster must also be specified.

[-foreground | -w [true]] - Foreground Process

This specifies whether the operation runs as a foreground process. If this parameter is specified, the default setting is true (the operation runs in the foreground). When set to true, the command will not return until the process completes. This parameter is only applicable to relationships with "Relationship Capability" of "Pre 8.2".

Examples

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

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