Converting a data protection destination to a SnapVault secondary

You convert a data protection destination volume to a SnapVault secondary volume after a tape seeding operation or after you lose a SnapVault secondary volume in a backup to disaster protection mirror cascade.

Before you begin

About this task

In the case of tape seeding, after you transfer the data from the tape to the volume, the volume is a data protection destination volume.

In the case of a SnapVault secondary volume to disaster protection volume cascade, if the SnapVault secondary volume is lost, you can resume SnapVault protection by creating a direct relationship between the SnapVault primary volume and the disaster protection destination volume. You must make the disaster protection destination volume a SnapVault secondary volume to do this.

Steps

  1. Break the data protection mirror relationship by using the snapmirror break command.
    The relationship is broken and the disaster protection volume becomes a read-write volume.
  2. Delete the existing data protection mirror relationship, if one exists, by using the snapmirror delete command.
  3. Remove the relationship information from the source SVM by using the snapmirror release command.
    This also deletes the Data ONTAP created Snapshot copies from the source volume.
  4. Create a SnapVault relationship between the primary volume and the read-write volume by using the snapmirror create command with the -type XDP parameter.
  5. Convert the destination volume from a read-write volume to a SnapVault volume and establish the SnapVault relationship by using the snapmirror resync command.
