When you unregister a host you remove it from being managed by the
Administrator server and destroy any nodes that the host manages. You can
unregister hosts from the GUI or by using the CLI.
GUI
Procedure
Select
Infrastructure > Hosts.
Choose an unregister option.
Option
Procedure
Unregister
Click
Unregister or select
Unregister
> Unregister. If no nodes are installed on the host, the
host is unregistered and deleted from the Administrator database. If nodes are
installed on the host, the operation fails.
Force Unregister
Select
Unregister
> Force unregister. Nodes are force uninstalled from the host
and the host, nodes, and application components deployed on the nodes are
deleted from the Administrator database. It's usually a good idea to first use
Unregister. If you decide to proceed with removing that data, use Force
Unregister.
CLI
Procedure
In the data file, specify a Host
element in base format (the default).
<Host name="SecondHost" />
In the build file, set the
action
attribute of the
AMXAdminTask element to
delete
and the
objectSelector attribute to
Host.
