Promote a Volume Collection

If you are using snapshot replication, you can use the promote procedure to have a downstream replication partner take ownership of the volume collection. The volumes that are associated with the volume collection are set to online, so they are available for reading and writing. All the ACLs from the upstream partner are moved to the downstream partner that you are promoting.

It is best to only use this procedure when the upstream array is not available.

If the volume collection uses multiple downstream replication partners, performing a promote halts all replication to the group that is being promoted. It does not affect replication to the other partner.

NOTE: The promote procedure only works with snapshot replicated volume collections. You cannot promote a synchronously replicated volume collection.
  1. Go to Manage → Data Protection.
  2. Select the volume collection that you want to promote.
  3. Click the ellipsis icon (…) and then Promote.
  4. Click OK.
  • Point your iSCSI initiators to the newly promoted volumes (members of the volume collection).
  • (Optional) Replicate the volume collection back to the original primary array from the newly promoted array.
  • Log into the original array (replication partner) and demote the original volume collection. See Demote a Volume Collection for more information.
