Power Off a Host Pool

Warning: Nerdio Manager does not install the BgInfo Azure extension during any automation or management process. However, the BgInfo extension may be installed either through a scripted action directly, or unintentionally, as stated in the Azure PowerShell module issues report.

Nerdio Manager allows you to power off all session hosts in a host pool.

Note: If you are working with a dynamic host pool with auto-scaling enabled, if you power off all the session hosts, auto-scaling powers them back on again. If you need to power everything off, you must temporarily disable auto-scaling.

To power off all session hosts in a host pool:

  1. Locate the host pool you want to power off.

  2. From the action menu, select Hosts > Power off.

  3. Enter the following information:

    • Run now or Schedule: Optionally, navigate to the Schedule tab to perform the power off operations during selected time frame(s). Otherwise, the power offs start as soon as you select OK. See Manage Schedules for Tasks for details about creating a schedule.

    • Log off users: Select this option to sign out users before powering off.

    • Restrict autoscale operations for (hours): Select this option to restrict auto-scale from scaling it in or out for the specified number of hours.

      • Type the number of hours for the auto-scale restriction.

    • Process Host in Groups Of: Type the number of power off operations that start at the same time.

      Warning: You must select this value with care. For example, if you have 150 hosts in the pool, you do not want to want to power them off one at a time. That would take too long. On the other hand, you do not want to run all 150 operations at the same time. That could overload your environment. So, you may want to run 25 operations per group.

    • Number of failures before aborting: Type the number of failed tasks before the process stops.

    • Messaging: Optionally, toggle on messaging to send a message to all the users on a session prior to performing the operation.

      • Delay: From the list, select the time to send the message before the operation starts.

      • Message: Type the text of the message to send.

  4. Once you have entered all the desired information, select Run now (not scheduled) or Save & close (scheduled).
