Install patches for ESXi hosts using the command esxcli

Step1.

First make sure the ESXi host has SSH enabled, which can be done in two ways.

Using ESXi Shell

By default, ESXi Shell (formerly known as Technical Support Mode or TSM) on ESXi is disabled. Local or remote access to the shell can be enabled if necessary.

Enable ESXi Shell for troubleshooting only. ESXi Shell can be enabled and disabled regardless of whether the host is running in lockdown mode.

ESXi Shell

Enable this service for local access to ESXi Shell.

SSH

Enable this service to remotely access ESXi Shell using SSH.

Method 1: Set up on console of ESXi host

Customize System/View Logs

Login root

Select Troubleshooting Options

Enable ESXi Shell and SSH

Method 2: Configure from the vShpere Client administration interface

Select Configuration-> Security Profiles-> Services-> Properties

Check the service properties, ESXi Shell and SSH are turned on. Modifications can be made via the option buttons.

Step2.

Upload Patches

From vSphere Client, select Storage-> Right Select Browse Datastore

Select Upload

Wait for the file to finish uploading

Step3.

upgrade patch

Right-click the ESXi host to enter maintenance mode, which should ensure that all virtual machines have been shut down.

Next, enter the command line interface and connect to EXSi through SecureCRT.

Verify that the host is in maintenance status again by querying the status of the EXSi host with the command.

~ # vim-cmd /hostsvc/hostsummary|grep Maintenance

inMaintenanceMode = true,

Check the current version

~ # vmware -v

VMware ESXi 5.5.0 build-3568722

~ # esxcli system version get

Product: VMware ESXi

Version: 5.5.0

Build: Releasebuild-3568722

Update: 3

Use the command to list the currently installed software

esxcli software vib list

Go to the directory where the uploaded patch is located

Use the following command to install the patch

esxcli software vib update -d "/vmfs/volumes/datastore1/ESXi550-201703001.zip"

After installing the patch, reboot the ESX host:

# reboot

Reconnect to the ESXi host via SSH after reboot.

Check upgraded version of host

vmware -v

Turn off maintenance mode of the host

~ # vim-cmd /hostsvc/maintenance_mode_exit

'vim.Task:haTask-ha-host-vim.HostSystem.exitMaintenanceMode-109447963'

Check after closing

~ # vim-cmd /hostsvc/hostsummary |grep inMaintenanceMode

inMaintenanceMode = false,
