Specifications

9 (Optional) On the Dynamic Patches and Extensions to Exclude page, review the list of patches or
extensions to be excluded and click Next.
10 On the Schedule page, specify a unique name and an optional description for the task.
11 Select Immediately to begin the process immediately after you complete the wizard, or specify a time
for the remediation process to begin, and click Next.
12 On the Host Remediation Options page, from the Power state drop-down menu, you can select the
change in the power state of the virtual machines and virtual appliances that are running on the hosts
to be remediated.
Option Description
Power Off virtual machines
Power off all virtual machines and virtual appliances before remediation.
Suspend virtual machines
Suspend all running virtual machines and virtual appliances before
remediation.
Do Not Change VM Power State
Leave virtual machines and virtual appliances in their current power state.
A host cannot enter maintenance mode until virtual machines on the host
are powered off, suspended, or migrated with vMotion to other hosts in a
DRS cluster.
Some updates require that a host enters maintenance mode before remediation. Virtual machines and
appliances cannot run when a host is in maintenance mode.
To reduce the host remediation downtime at the expense of virtual machine availability, you can choose
to shut down or suspend virtual machines and virtual appliances before remediation. In a DRS cluster,
if you do not power off the virtual machines, the remediation takes longer but the virtual machines are
available during the entire remediation process, because they are migrated with vMotion to other hosts.
13 (Optional) Select Retry entering maintenance mode in case of failure, specify the number of retries,
and specify the time to wait between retries.
Update Manager waits for the retry delay period and retries putting the host into maintenance mode as
many times as you indicate in Number of retries field.
14 (Optional) Select Disable any removable media devices connected to the virtual machine on the host.
Update Manager does not remediate hosts on which virtual machines have connected CD, DVD, or
floppy drives. In cluster environments, connected media devices might prevent vMotion if the
destination host does not have an identical device or mounted ISO image, which in turn prevents the
source host from entering maintenance mode.
After remediation, Update Manager reconnects the removable media devices if they are still available.
15 (Optional) Select the check box under ESXi 5.x Patch Settings to enable Update Manager to patch
powered on PXE booted ESXi hosts.
This option appears only when you remediate hosts against patch or extension baselines.
16 Click Next.
