Evacuate the replications data from a datastore

For performing maintenance operations on a local datastore in the cloud site evacuate all incoming replications and replication data placed on that datastore. To evacuate the replications from the datastore at once, apply an alternative storage policy for all incoming replications that reside on the datastore.
Verify that
VMware Cloud Director Availability
 4.4 or later is deployed in the cloud site for evacuating datastore clusters.
  • Evacuating a datastore invalidates all
    VMware Cloud Director Availability
     backups created priorly and they cannot restore the replications.
    To ensure restoring from a backup is successful, create a backup every time the replications are moved from one datastore to another. For information about restoring, see Restore the appliances in the cloud.
  • Evacuating a datastore might take several hours until completed and depends on the amount of data for transferring.
  • Since
    VMware Cloud Director Availability
     4.4 evacuating replicas from individual members of datastore clusters is supported. Replications on a member datastore can move only to a different (for example, temporary) storage policy, they cannot be rebalanced within the other member datastores within the same cluster. After maintenance completes, the replications can be moved back from the temporary location to the original datastore cluster.
  1. Log in to the management interface of the
    Cloud Director Replication Management Appliance
    .
    1. In a Web browser, go to
      https://
      Appliance-IP-Address
      /ui/admin
      .
    2. Select
      Appliance login
       or
      SSO login
       and enter the
      root
       or the
      single sign-on
       user credentials.
    3. Click
      Login
      .
  2. In the left pane under
    System
    , click
    Datastores
    .
  3. To show the replications that are placed on a datastore that displays replications counters, click
    Preview
    .
    For datastore clusters, expand to show the cluster members.
  4. Select a local datastore or a cluster member that displays replications counters and click
    Evacuate
    .
  5. In the
    Evacuate datastore
     window, select the destination storage policy for all incoming replications residing on the datastore and click
    Evacuate
    .
    • Reset current storage policy
       applies the current storage policy to each matching replication. After removing or adding datastores to the storage policy, to make the matching replications compliant with their storage policy this option can move the replication replica files.
    • Any
       stores all the replications to all the shared datastores that have
      Any
       storage policy applied.
    • pVDC Storage policy
       applies the selected storage policy to all matching replications. If the
      pVDC Storage policy
       is not exposed to a tenant data center, the replications of this tenant remain placed on the datastore.
VMware Cloud Director Availability
 applies the selected storage policy and starts evacuating the incoming replications and replica files from the selected local datastore in the cloud site.
You can track the progress of the

 task by clicking

 in the left pane.
