When you place a View Transfer Server instance in maintenance mode, you suspend active data transfers and prevent future data transfers for local desktops on that View Transfer Server instance. When you take a View Transfer Server instance out of maintenance mode, suspended transfers can be resumed from the client and future transfers can occur.

When all View Transfer Server instances are in maintenance mode, you can migrate the Transfer Server repository. See Migrate the Transfer Server Repository to a New Location.

While a View Transfer Server instance is added to View Manager and in active mode, its DRS automation policy is set to Manual, which effectively disables DRS. To migrate a View Transfer Server instance to another ESX host or datastore, place the instance in maintenance mode before you begin the migration.

Note

As a best practice, before you update or migrate virtual machines that can be used in local mode, place View Transfer Server in maintenance mode and make sure that all data transfers are complete or stopped. For example, place View Transfer Server in maintenance mode before you use Storage vMotion to migrate full virtual machines or the View Composer rebalance operation to migrate linked clones to other datastores. This practice prevents local mode data transfers from taking place while maintenance operations are performed on the virtual machines.

1

In View Administrator, click View Configuration > Servers.

2

Click the Transfer Servers tab and select a View Transfer Server instance.

3

Click Enter Maintenance Mode.

4

If transfers are currently active, choose whether to cancel the active transfers or wait until active transfers are completed before placing View Transfer Server in maintenance mode.

If you cancel active transfers, View Transfer Server enters maintenance mode immediately.

If you allow active transfers to finish, View Transfer Server enters a Maintenance Mode Pending state. When the current disk transfer is completed, View Transfer Server enters maintenance mode.

Note

Allowing active transfers to finish ensures that the current disk is transferred. However, virtual machines contain multiple disks. A transfer operation such as a desktop checkout might not be completed if no other View Transfer Server instances are available to transfer any remaining disks. When a View Transfer Server instance is taken out of maintenance mode, suspended transfers can be resumed.

5

Click OK.

When you are ready to take View Transfer Server out of maintenance mode, select the View Transfer Server instance and click Exit Maintenance Mode. Suspended transfers can be resumed and new data transfers can start.
