SCVMM: UPS without Outlet Groups

Example 1: Turn off the UPS enabled, no shutdown command file configured.

PowerChute is installed on the physical System Center Virtual Machine Manager (SCVMM) machine and configured for a Single/Redundant UPS configuration with several Hyper-V hosts managed by SCVMM. The option to Turn off the UPS is enabled on the Shutdown settings page. No shutdown command file is configured.  

When a critical UPS event, such as On Battery occurs, the following sequence is triggered.

1. PowerChute reports that the UPS is on battery.
2. After the shutdown delay configured for the On Battery event has elapsed, PowerChute sends a command to turn off the UPS.
3. PowerChute sends a command to SCVMM to start a maintenance mode task on the hosts.
4. After 2 minutes (Maintenance Mode duration), PowerChute issues a Host Shutdown command (available on SCVMM 2012 only).
5. After a few seconds PowerChute issues the Operating System Shutdown Command on the SCVMM machine.
6. After a 70 second delay the Operating System shutdown starts.
7. The UPS will wait the amount of time indicated by one of the following, whichever is greater:
   
   Low Battery Duration or Maximum Required Delay.
   These are shown on the UPS Shutdown page in the NMC user interface.
8. After this delay, a further non-configurable two minute delay is counted down.
9. The UPS will then turn off after the user-configurable Shutdown Delay time has elapsed.
   This is configurable on the UPS Shutdown page in the NMC user interface.

It is recommended that the Low Battery Duration is configured to allow enough time for the operating system shutdown to complete. Ideally, the operating system should have shut down before the non-configurable two minute delay (step 8) starts to count down.

Example 2: Turn off the UPS enabled, shutdown command file configured.

PowerChute is installed on the SCVMM physical machine and configured for a Single/Redundant UPS configuration with several Hyper-V hosts managed by SCVMM. The option to Turn off the UPS is enabled on the Shutdown settings page. A shutdown command file is configured.

When a critical UPS event, such as On Battery occurs, the following sequence is triggered.

1. PowerChute reports that the UPS is on battery. 
2. After the shutdown delay configured for the On Battery event has elapsed, PowerChute sends a command to turn off the UPS. UPS turnoff starts.
3. PowerChute sends a command to SCVMM to start a maintenance mode task on the hosts.  
4. After 2 minutes (Maintenance Mode duration), PowerChute executes the shutdown command file.
5. After the duration configured for the shutdown command file has elapsed, PowerChute issues the host shutdown and operating system shutdown commands.
6. An additional 70 second delay is counted down before the operating system starts to shut down.
7. The UPS will wait the amount of time indicated by one of the following, whichever is greater:
   
   Low Battery Duration or Maximum Required Delay.
   These are shown on the UPS Shutdown page in the NMC user interface.
8. After this delay, a further non-configurable two minute delay is counted down.
9. The UPS will then turn off after the user-configurable Shutdown Delay time has elapsed (this is configurable on the UPS Shutdown page in the NMC user interface).

It is recommended that the Low Battery Duration is configured to allow enough time for the shutdown command file and operating system shutdown to complete. Ideally, the operating system should have shut down before the two minute delay (step 8) starts to count down.

Example 3: Turn off the UPS enabled, shutdown command file configured, Execute Command File after Host Shutdown enabled.

PowerChute is installed on the SCVMM physical machine and configured for a Single/Redundant UPS configuration with several Hyper-V hosts managed by SCVMM. The option to Turn off the UPS is enabled on the Shutdown settings page. A shutdown command file is configured and Execute Command File after Host Shutdown is enabled, with a 30 second delay.

When a critical UPS event, such as On Battery occurs, the following sequence is triggered.

1. PowerChute reports that the UPS is on battery. 
2. After the shutdown delay configured for the On Battery event has elapsed, PowerChute sends a command to turn off the UPS. UPS turnoff starts.
3. PowerChute sends a command to SCVMM to start a maintenance mode task on the hosts.  
4. After 2 minutes (Maintenance Mode duration), PowerChute issues the host shutdown command.
5. Following the configured 30 second delay, PowerChute executes the shutdown command file.
6. After the duration configured for the shutdown command file has elapsed, PowerChute issues the host shutdown and operating system shutdown commands. An additional 70 second delay is counted down before the operating system starts to shut down.
7. The UPS will wait the amount of time indicated by one of the following, whichever is greater:
   Low Battery Duration or Maximum Required Delay. These are shown on the UPS Shutdown page in the NMC user interface.
8. After this delay, a further non-configurable two minute delay is counted down.
9. The UPS will then turn off after the user-configurable Shutdown Delay time has elapsed (this is configurable on the UPS Shutdown page in the NMC user interface).

It is recommended that the Low Battery Duration is configured to allow enough time for the shutdown command file and operating system shutdown to complete. Ideally, the operating system should have shut down before the two minute delay (step 8) starts to count down.
