Creating a consistency group relationship

04/29/2021 Download PDF of this page

You must create a SnapMirror consistency group which also establishes the synchronous consistency group relationship.

Before you begin

The following prerequisites and restrictions apply:

You must be a cluster or storage VM administrator
You must have a SnapMirror Synchronous license
The destination volumes must be type DP
The primary and the secondary storage VM must be in a peered relationship
All constituent volumes in a consistency group must be in a single Storage VM
You cannot establish SM-BC consistency group relationships across ASA clusters and non-ASA clusters

About this task

You must create the consistency group relationship from the destination cluster. You can map up to 12 constituents using the cg-item-mappings parameter on the snapmirror create command.

Steps

Create a consistency group and constituent relationship. This example creates two consistency groups: srccg with constituent volumes vol1 and vol2, and dstcg with constituent volumes vol1_dr and vol2_dr.

destination::> snapmirror create -source-path vs1_src:/cg/cg_src -destination-path vs1_dst:/cg/cg_dst -cg-item-mappings vol_src1:@vol_dst1,vol_src2:@vol_dst2 -policy AutomatedFailover
