You might want to take a managed server offline for various reasons. For example:

To do a rolling upgrade of virtualization software
To add or test connectivity to a new network
To diagnose an underlying hardware issue
To add connectivity to a new storage system.

Use XenCenter to take a server offline temporarily by placing it into maintenance mode. When you place a server in a resource pool into maintenance mode, all running VMs on it are automatically migrated to another server in the same pool. If the server is the pool coordinator, a new pool coordinator is also selected for the pool.

When Workload Balancing is enabled, it migrates the running VMs on that server to their optimal servers when available. These migrations are based on Workload Balancing recommendations: performance data, your placement strategy, and performance thresholds.

While a server is maintenance mode, you cannot create or start any VMs on it.

To place a server in maintenance mode

In the Infrastructure view of the XenCenter resources pane (left pane), select the server and then do one of the following:

Right-click the server name and choose Enter Maintenance Mode from the shortcut menu.
On the Server menu, select Enter Maintenance Mode.

After all running VMs successfully migrate off the server, the server’s status in the Resources pane changes to show the server maintenance mode icon. Server maintenance mode icon - a Server icon with a blue square on top.

To take a server out of maintenance mode

In the Infrastructure view of the XenCenter resources pane (left pane), select the server and then do one of the following:

Right-click the server name and choose Exit Maintenance Mode on the shortcut menu.
On the Server menu, select Exit Maintenance Mode.
