Replicator Service
 maintenance mode

To prepare a
Replicator Service
 instance for maintenance without disrupting replications, you can evacuate the incoming replications from the
Replicator Service
 instance to other local
Replicator Service
 instances in the cloud site.
  • Verify that
    VMware Cloud Director Availability
     is successfully deployed in the cloud site.
  • Verify that more than one
    Replicator Service
     instance is operational in the cloud site.
  • Verify that the clean-up task is complete after using a test failover for any incoming replication. If the
    Replicator Service
     contains a test failed over virtual machine, attempting to enter a maintenance mode shows a
    Operation aborted due to an unexpected error
     message. Before entering maintenance mode, you must perform a test cleanup on the test failed over virtual machine or vApp.
The
Replicator Service
 instance must be placed in maintenance mode in each site where it is registered. This procedure is a two-step process, performed first in the local site, then repeated in the remote sites:
  1. In the local site, placing the
    Replicator Service
     instance in maintenance mode migrates all incoming cloud replications to other
    Replicator Service
     instances in the local site. Also,
    VMware Cloud Director Availability
     migrates all incoming and outgoing replications from and to on-premises sites.
  2. In the remote site, migrate the remaining outgoing cloud replications from this
    Replicator Service
     instance to other
    Replicator Service
     instances. Log in to the remote site and place in maintenance mode the same
    Replicator Service
     instance. Repeat this step in each remote site, where this
    Replicator Service
     instance is remotely registered.
New replications are placed on
Replicator Service
 instances that are not in maintenance mode.
  1. Log in to the
    Manager Service
     service management interface.
    1. In a Web browser, go to
      https://
      Appliance-IP-Address
      :8441/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, click
    Replicators
    .
  3. To evacuate the incoming replications, select the local
    Replicator Service
     instance and click
    Enter Maintenance Mode
    .
  4. To evacuate the outgoing replications from this
    Replicator Service
     instance, log in to the
    Manager Service
     in the remote site and repeat this procedure.
    In the remote site, select the same
    Replicator Service
     instance that is remotely registered.
    Repeat step 4 for all cloud sites, where the
    Replicator Service
     instance is remotely registered.
After placing a
Replicator Service
 instance in maintenance mode from both the local site and all remote sites where it is registered,
VMware Cloud Director Availability
 evacuates all replications from that
Replicator Service
 instance. The
Replicator Service
 instance is ready for maintenance operations.
After performing the maintenance operations, in the local site click
Exit Maintenance Mode
. To repopulate the
Replicator Service
 instance with replications, you must rebalance the replications. For more information, see Rebalance the replications across the Replicator Service instances.
