Enabling a Standalone Host to Use a Software Specification

Starting with vSphere 8.0, you can use the
vSphere Lifecycle Manager
to manage the life cycle of standalone hosts in your
vCenter Server
system.
You can add a standalone host to a
vCenter Server
instance under a data center object or into a folder. See ESXi Hosts. If you remove a host from a cluster but leave it in the data center, the host is also considered a standalone host.
To manage a standalone host with a software specification, you must first enable the
vSphere Lifecycle Manager
on that host. You can run a preliminary check to establish whether the standalone host meets all requirements for enabling the
vSphere Lifecycle Manager
.
Call the
check_Task(host_ID, check_spec)
method of the
com.vmware.esx.settings.hosts.enablement.Software
interface and pass as arguments the host identifier and a
CheckSpec
instance
. The pre-checks that you can skip before enabling the
vSphere Lifecycle Manager
on a standalone host are the same as for a cluster.
To enable
vSphere Lifecycle Manager
on a standalone host,
call the
enable_Task(host_ID, check_spec)
method of the
com.vmware.esx.settings.hosts.enablement.Software
interface. Pass as arguments the host unique identifier and optionally, a
com.vmware.esx.settings.hosts.enablement.SoftwareTypes.EnableSpec
instance to define whether any checks can be skipped during the feature enablement operation
. Currently, you can skip only the check for orphaned vSphere Installation Bundles (VIBs).
