Procedure
1 Use the vSphere Client or the vSphere Web Client to connect to a vCenter Server system with which
Update Manager is registered.
2 Depending on the client you use to connect to vCenter Server perform the following steps.
Client Steps

3 Select the check boxes for features that you want to disable or enable.
Option Description
Distributed Power Management
(DPM)
VMware DPM monitors the resource use of the running virtual machines
in the cluster. If sucient excess capacity exists, VMware DPM
recommends moving virtual machines to other hosts in the cluster and
placing the original host into standby mode to conserve power. If the
capacity is insucient, VMware DPM might recommend returning
standby hosts to a powered-on state.
If you do not choose to disable DPM, Update Manager skips the cluster on
which VMware DPM is enabled. If you choose to temporarily disable
VMware DPM, Update Manager disables DPM on the cluster, remediates
the hosts in the cluster, and re-enables VMware DPM after remediation is
complete.
High Availability (HA) admission
control
Admission control is a policy used by VMware HA to ensure failover
capacity within a cluster. If HA admission control is enabled during
remediation, the virtual machines within a cluster might not migrate with
vMotion.
If you do not choose to disable HA admission control, Update Manager
skips the cluster on which HA admission control is enabled. If you choose
to temporarily disable HA admission control, Update Manager disables
HA admission control, remediates the cluster, and re-enables HA
admission control after remediation is complete.
Fault Tolerance (FT)
FT provides continuous availability for virtual machines by automatically
creating and maintaining a secondary virtual machine that is identical to
the primary virtual machine. If you do not choose to turn o FT for the
virtual machines on a host, Update Manager does not remediate that host.
Enable parallel remediation for
hosts in cluster
Update Manager can remediate hosts in clusters in a parallel manner.
Update Manager continuously evaluates the maximum number of hosts it
can remediate in parallel without disrupting DRS seings. If you do not
select the option, Update Manager remediates the hosts in a cluster
sequentially.
By design only one host from a Virtual SAN cluster can be in a
maintenance mode at any time. Update Manager remediates hosts that are
part of a Virtual SAN cluster sequentially even if you select the option to
remediate them in parallel.
Migrate powered off and suspended
virtual machines to other hosts in
the cluster, if a host must enter
maintenance mode
Update Manager migrates the suspended and powered o virtual
machines from hosts that must enter maintenance mode to other hosts in
the cluster. You can select to power o or suspend virtual machines before
remediation in the Maintenance Mode Seings pane.
