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

{ -S, -source-path {<[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). 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" . For SnapMirror relationships with an AltaVault source, the source endpoint is specified in the form hostip:/share/share-name . For SnapMirror relationships with a SolidFire source, the source endpoint is specified in the form hostip:/lun/name .

| [-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. For relationships with volumes as endpoints, if this parameter is specified, parameters -source-volume and for relationships with "Relationship Capability" of "Pre 8.2" , -source-cluster must also be specified. 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. If this parameter is specified, parameters -source-vserver and for relationships with "Relationship Capability" of "Pre 8.2" , -source-cluster must also be specified. This parameter is not supported for relationships with non-Data ONTAP source endpoints.

[-w, -foreground <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 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
