Disconnecting And Reconnecting A Host - VMware 4817V62 - vSphere - PC Administration Manual

vSphere Basic System Administration
2 Connects to the managed host.
If the wizard cannot connect to the managed host, the managed host is not added to the inventory.
3 Verifies that the managed host is not already being managed.
If the host is already being managed by another vCenter Server system, vCenter Server displays a message.
If the vCenter Server can connect to the managed host, but for some reason cannot remain connected, the
host is added, but is in a disconnected state.
4 Reads the number of processors on the managed host and allocates the appropriate number of licenses.
The number of processors is stored in the vCenter Server database and is verified upon each managed
host reconnection and vCenter Server system startup.
5 Verifies that the managed host version is supported.
If it is not, and the managed host version can be upgraded, vCenter Server prompts you to perform an
upgrade.
6 Imports existing virtual machines.

Disconnecting and Reconnecting a Host

You can disconnect and reconnect a host that is being managed by vCenter Server. Disconnecting a managed
host does not remove it from vCenter Server; it temporarily suspends all monitoring activities performed by
vCenter Server.
The managed host and its associated virtual machines remain in the vCenter Server inventory. By contrast,
removing a managed host from vCenter Server removes the managed host and all its associated virtual
machines from the vCenter Server inventory.
Disconnect a Managed Host
Use the vSphere Client to disconnect a managed host from vCenter Server.
Procedure
1 From the vSphere Client connected to a vCenter Server system, display the inventory and click the
managed host to disconnect.
2 Right-click the host and select Disconnect from the pop-up menu.
3 In the confirmation dialog box that appears, click Yes.
If the managed host is disconnected, the word "disconnected" is appended to the object name in
parentheses, and the object is dimmed. All associated virtual machines are similarly dimmed and labeled.
Reconnect a Managed Host
Use the vSphere Client to reconnect a managed host to a vCenter Server system.
Procedure
1 From the vSphere Client connected to a vCenter Server system, display the inventory and click the
managed host to reconnect.
2 Right-click the host and select Connect from the pop-up menu.
When the managed host's connection status to vCenter Server is changed, the statuses of the virtual
machines on that managed host are updated to reflect the change.
