Option Details
Disable Fault Tolerance (FT) if it is
enabled for the VMs on the selected
hosts.
If FT is turned on for any of the virtual machines on a host,
Update Manager does not remediate that host.
For FT to be enabled, the hosts on which the Primary and Secondary
virtual machines run must be of the same version and must have the same
patches installed. If you apply dierent patches to these hosts, FT cannot
be re-enabled.
Enable parallel remediation for the
hosts in the selected clusters.
Remediate hosts in clusters in a parallel manner. If the seing is not
selected, 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.
By default, Update Manager continuously evaluates the maximum number
of hosts it can remediate concurrently without disrupting DRS seings.
You can limit the number of concurrently remediated hosts to a specic
number.
N Update Manager remediates concurrently only the hosts on which
virtual machines are powered o or suspended. You can choose to power
o or suspend virtual machines from the Power State menu in the
Maintenance Mode Seings pane on the Host Remediation Options page.
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 choose to power o or suspend virtual machines
before remediation in the Maintenance Mode Seings pane.
17 (Optional) Generate a cluster remediation options report by clicking Generate Report on the Cluster
Remediation Options page and click Next.
18 On the Ready to Complete page, click Finish.
N In the Recent Tasks pane, the remediation task is displayed and will remain at about 22 percent for
most of the process. The process is still running and will take approximately 15 minutes to complete.
Installing or Upgrading Hosts by Using a Script
You can quickly deploy ESXi hosts by using scripted, unaended installations or upgrades. Scripted
installations or upgrades provide an ecient way to deploy multiple hosts.
The installation or upgrade script contains the installation seings for ESXi. You can apply the script to all
hosts that you want to have a similar conguration.
For a scripted installation or upgrade, you must use the supported commands to create a script. You can edit
the script to change seings that are unique for each host.
The installation or upgrade script can reside in one of the following locations:
n
FTP server
n
HTTP/HTTPS server
n
NFS server
n
USB ash drive
n
CD-ROM drive
