You can convert replication relationships between volumes to a replication relationship between the storage virtual machines (SVMs) that own the volumes, provided that each volume on the source (except the root volume) is being replicated, and each volume on the source (including the root volume) has the same name as the volume on the destination.

About this task

Use the volume rename command when the SnapMirror relationship is idle to rename destination volumes if necessary.

Steps

  1. From the destination SVM or the destination cluster, run the following command to resync the source and destination volumes:

    snapmirror resync -source-path <SVM:volume> -destination-path <SVM:volume> -type DP|XDP -policy <policy>

    For complete command syntax, see the man page.

    Note

    Although resync does not require a baseline transfer, it can be time-consuming. You might want to run the resync in off-peak hours.

    The following example resyncs the relationship between the source volume volA on svm1 and the destination volume volA on svm_backup:

    cluster_dst::> snapmirror resync -source-path svm1:volA -destination-path svm_backup:volA

  2. Create an SVM replication relationship between the source and destination SVMs, as described in Replicating SVM configurations.

    You must use the -identity-preserve true option of the snapmirror create command when you create your replication relationship.

  3. Stop the destination SVM:

    vserver stop -vserver SVM

    For complete command syntax, see the man page.

    The following example stops the destination SVM svm_backup:

    cluster_dst::> vserver stop svm_backup

  4. From the destination SVM or the destination cluster, run the following command to resync the source and destination SVMs:

    snapmirror resync -source-path <SVM>: -destination-path <SVM>: -type DP|XDP -policy <policy>

    For complete command syntax, see the man page.

    Note

    You must enter a colon (:) after the SVM name in the -source-path and -destination-path options. See the example below.

    Although resync does not require a baseline transfer, it can be time-consuming. You might want to run the resync in off-peak hours.

    The following example resyncs the relationship between the source SVM svm1 and the destination SVM svm_backup:

    cluster_dst::> snapmirror resync -source-path svm1: -destination-path svm_backup:
