You can easily update your vCenter Server Appliance (VCSA) offline by downloading a product patch ISO and via the CLI.

Download the latest patch from VMware Patch Download Center. Select VC from the Search by Product drop-down menu, then select the correct version (i.e. 6.0 or 6.5). Download the patch ISO and attach it to the VCSA.

Log in to the shell (using SSH or VMRC) and initiate the update:

  1. Stage the ISO updates:
    software-packages stage --iso
  2. Optionally, you can view the list of packages to be updated:
    software-packages list --staged
  3. To install the updates, run:
    software-packages install --staged

After the update has finished, you will have to reboot the VCSA.

You can use either esxcli or vicfg-hostops to enter/exit maintenance mode.

esxcli

  • Enter: esxcli system maintenanceMode set --enable true
  • Exit: esxcli system maintenanceMode set --enable false

vicfg-hostops

  • Enter: vicfg-hostops --operation enter
  • Exit: vicfg-hostops --operation exit

Note that you can use vicfg-hostops --operation info to check whether the host is finished with entering maintenance mode or is still busy.

PowerCLI

After connecting to the host or vCenter server:

  • Enter: Get-VMHost <name-of-host> | Set-VMHost -State Maintenance
  • Exit: Get-VMHost <name-of-host> | Set-VMHost -State Connected

Internet Explorer 11 has an integrated Adobe Flash Player plugin, but on Windows Server 2016, this plugin is not active by default. In fact, checking the available plugins within IE does not show the plugin as installed. This is because the plugin is not activated by default (which is somewhat logic as it's considered a security risk).

The package containing the plugin does exist on Windows Server 2016 (with GUI) but is not active. You can manually activate the plugin through dism:

dism /online /add-package /packagepath:"C:\Windows\servicing\Packages\Adobe-Flash-For-Windows-Package~31bf3856ad364e35~amd64~~10.0.14393.0.mum"

After adding the package, you will have to reboot for it  ...
