Resume SnapMirror workflow

Goal

The Resume SnapMirror workflow restarts (or unquiesces) the data transfers between source and destination volumes in SnapMirror or SnapVault relationships that have been quiesced.

Prerequisites

 

         You must be running Data ONTAP 8.2 or later on the affected cluster.

         A SnapMirror or SnapVault relationship must exist between the source and destination volumes.

         The SnapMirror or SnapVault relationship must be in a quiesced state.

About this workflow

The Resume SnapMirror workflow is executed to resume data transfer between source and destination volumes in a SnapMirror or SnapVault relationship after that relationship has been quiesced, usually prior to a SnapMirror break operation.

WFA user actions

o   Destination storage virtual machine (SVM)

o   Destination volume

3.       Click Execute Now.

WFA User input descriptions

The mandatory and optional user inputs for the Resume SnapMirror workflow are described below.

Input

Description

Destination Cluster

(mandatory)

The name of the cluster in which the destination volume of the quiesced SnapMirror or SnapVault relationship that you want to resume resides

Destination Storage Virtual Machine Name

(mandatory)

The name of the SVM in which the destination volume of the quiesced SnapMirror or SnapVault relationship that you want to resume resides

Destination Volume

(mandatory)

Destination volume of the quiesced SnapMirror or SnapVault relationship that you want to resume

 

Workflow sequence

 

When completing the Resume SnapMirror workflow, WFA executes the following sequence of tasks:

 

1.       Resume SnapMirror. WFA calls the Resume SnapMirror command to unquiesce the SnapMirror or SnapVault relationship whose destination volume was specified for this workflow and resume data transfer between the source and destination volumes.

Result

 

After the Resume SnapMirror workflow is executed, future transfers are enabled for the now unquiesced SnapMirror or SnapVault relationship. Scheduled transfers are resumed at the next scheduled time. Restart checkpoints are used if possible. When a SnapMirror relationship is resumed, it remains unquiesced across reboots and fail-overs.
