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

When attempting to register the vSphere Replication appliance to the PSC, you may encounter this error:

Error
Server returned 'request expired' less than 0 seconds after request was issued, but it shouldn't have expired for at least 600 seconds.

On the appliance, look in the log file /opt/vmware/hms/logs/hms.log: if you see messages similar to the following, the time of the replication appliance and the PSC may not be in sync.

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  ...

You can easily test the availability of an NTP server by using ntpdate. This utility is a command line utility which performs a one-time time sync to the specified NTP server but it can also be used to query the time without setting it by using the -q parameter:

$ ntpdate -q 10.30.0.1
server 10.30.0.1, stratum 4, offset 0.001217, delay 0.04170
 8 Jan 10:19:36 ntpdate[2376]: adjust time server 10.30.0.1 offset 0.001217 sec

You can very easily update your appliance to the latest version of OpenVPN by following these instructions:

Find the download URL to download the new package. You do not have to download it, you just need the link: using your webbrowser, navigate to Software Packages, click on Ubuntu, then copy the link for the Ubuntu 14 amd/x86 64-bit package. Use that URL in the next step.

Log on to the appliance using SSH (or directly on the console), using the root account and the password (you should have this).

Download the package using wget:wget download_URL_you_copied

This will download the package and store it in the current folder on the appliance.

Install the package:dpkg -i http://swupdate.  ...

Currently, it's not possible to set up HTML-based auto-reply messages on shared or resource mailboxes, as you cannot directly log on to OWA to set the message. Through Powershell, you can do this quite easily.

First, create two HTML-files containing your internal and external message. You do not have to specify the <html> and <body> tags. Save these to a convenient location. Be sure to save them as regular text files, with extension .txt.

Next, log on to Exchange Online management shell.

cd to the location of the two message files, and load them to variables:

$internalmessage = Get-Content -Path internalmessage.txt

$externalmessage = Get-Content -Path externalmessage.txt  ...
