You might want to exclude network, name service, and other settings from an SVM replication relationship to avoid conflicts or configuration differences with the destination SVM.

You can use the -identity-preserve false option of the snapmirror create command to replicate only the volumes and security configurations of an SVM. Some protocol and name service settings are also preserved.

About this task

For a list of preserved protocol and name service settings, see Configurations replicated in SVM DR relationships.

For complete command syntax, see the man page.

Before you begin

The source and destination clusters and SVMs must be peered.

For more information, see Create a cluster peer relationship and Create an SVM intercluster peer relationship.

Steps

  1. Create a destination SVM:

    vserver create -vserver SVM -subtype dp-destination

    The SVM name must be unique across the source and destination clusters.

    The following example creates a destination SVM named svm_backup:

    cluster_dst:> vserver create -vserver svm_backup -subtype dp-destination

  2. From the destination cluster, create an SVM peer relationship using the vserver peer create command.

    For more information, see Create an SVM intercluster peer relationship.

  3. Create a replication job schedule:

    job schedule cron create -name job_name -month month -dayofweek day_of_week -day day_of_month -hour hour -minute minute

    For -month, -dayofweek, and -hour, you can specify all to run the job every month, day of the week, and hour, respectively.

    Note

    The minimum supported schedule (RPO) for FlexVol volumes in an SVM SnapMirror relationship is 15 minutes. The minimum supported schedule (RPO) for FlexGroup volumes in an SVM SnapMirror relationship is 30 minutes.

    The following example creates a job schedule named my_weekly that runs on Saturdays at 3:00 a.m.:

    cluster_dst::> job schedule cron create -name my_weekly -dayofweek "Saturday" -hour 3 -minute 0

  4. Create a replication relationship that excludes network, name service, and other configuration settings:

    snapmirror create -source-path SVM: -destination-path SVM: -type DP|XDP -schedule schedule -policy policy -identity-preserve false

    Note

    You must enter a colon (:) after the SVM name in the -source-path and -destination-path options. See the examples below. You must run this command from the destination SVM or the destination cluster.

    The following example creates a SnapMirror DR relationship using the default MirrorAllSnapshots policy. The relationship excludes network, name service, and other configuration settings from SVM replication:

    cluster_dst::> snapmirror create -source-path svm1: -destination-path svm_backup: -type XDP -schedule my_daily -policy MirrorAllSnapshots -identity-preserve false

    The following example creates a unified replication relationship using the default MirrorAndVault policy. The relationship excludes network, name service, and other configuration settings:

    cluster_dst:> snapmirror create svm1: -destination-path svm_backup: -type XDP -schedule my_daily -policy MirrorAndVault -identity-preserve false

    Assuming you have created a custom policy with the policy type async-mirror, the following example creates a SnapMirror DR relationship. The relationship excludes network, name service, and other configuration settings from SVM replication:

    cluster_dst::> snapmirror create -source-path svm1: -destination-path svm_backup: -type XDP -schedule my_daily -policy my_mirrored -identity-preserve false

    Assuming you have created a custom policy with the policy type mirror-vault, the following example creates a unified replication relationship. The relationship excludes network, name service, and other configuration settings from SVM replication:

    cluster_dst::> snapmirror create -source-path svm1: -destination-path svm_backup: -type XDP -schedule my_daily -policy my_unified -identity-preserve false

  5. Stop the destination SVM:

    vserver stop

    SVM name

    The following example stops a destination SVM named dvs1:

    destination_cluster::> vserver stop -vserver dvs1

  6. If you are using SMB, you must also configure an SMB server.

    See SMB only: Creating an SMB server.

  7. From the destination SVM or the destination cluster, initialize the SVM replication relationship:

    snapmirror initialize -source-path SVM_name: -destination-path SVM_name:

After you finish

You must configure the network and protocols on the destination SVM for data access in the event a disaster occurs.
