VMware with HPE SimpliVity Support: UPS with Outlet Groups
Example 1a: Turn off the Outlet Group enabled, no shutdown command
file or SSH action configured, external vCenter Server Appliance, PowerChute
on physical Windows machine.
PowerChute is installed on a physical machine outside the Cluster, configured
for a Single/Redundant UPS configuration with 2 nodes in a Cluster. The
option to Turn off the Outlet Group is enabled on the Shutdown Settings
page, Delay Host Maintenance Mode is enabled on the Virtualization Settings
page. No shutdown command file or SSH action configured. The durations
in this example are as follows:
- VM and vApp Shutdown Duration = 120 seconds
- OmniStack Virtual Controller Shutdown Duration = 120 seconds
- Delay Host Maintenance Mode = 30 seconds
When a critical UPS event, such as On Battery occurs, the following
sequence is triggered.
- PowerChute reports
that the UPS is on battery.
- After the shutdown
delay configured for the On Battery event has elapsed, PowerChute
issues a command to turn off the Outlet Group and the Outlet Group
turn off starts.
- PowerChute starts
to shut down User VMs and vApps.
- After 2 minutes
(VM/vApp Shutdown Duration), PowerChute shuts down the HPE SimpliVity
OmniStack Virtual Controller.
- After 120 seconds
(OVC Shutdown Delay), the VMware Hosts enter maintenance mode and
are shut down sequentially if all VMs are powered off, otherwise
the maintenance mode task is cancelled. The delay between placing
each host into maintenance mode is the value set for Delay Maintenance
Mode (30 seconds).
- PowerChute issues
the operating system shutdown command.
- After a 70 second
delay, the operating system on the physical machine running PowerChute
starts to shut down.
The Outlet
Group will turn off after the Power
Off Delay (configurable on the Configuration
– Outlet Group page in the
NMC user interface) has elapsed.
If registered with the Main Outlet
Group, the UPS will wait for any Switched Outlet Groups to turn off
before the Main Outlet Group turnoff starts.
If registered with a Switched Outlet
Group, only that delay is counted down.
It is recommended that the Outlet Group Power
Off Delay is configured to allow enough time for the operating
system shutdown to complete. You should allow extra time to ensure that
the Outlet Group does not turn off before the operating system.
Example 1b: Turn off the Outlet Group enabled, no shutdown command
file or SSH action configured, internal vCenter Server Appliance, PowerChute
deployed as a VM.
PowerChute is installed as a VM inside the Cluster, configured for a
Single/Redundant UPS configuration with 2 nodes in a Cluster. HA is enabled
on the Cluster and there is an internal vCenter Server Appliance. The
option to Turn off the Outlet Group is enabled on the Shutdown Settings
page, Delay Host Maintenance Mode is enabled on the Virtualization Settings
page. No shutdown command file or SSH action configured. The durations
in this example are as follows:
- VM and vApp Shutdown Duration = 120 seconds
- OmniStack Virtual Controller Shutdown Duration = 120 seconds
- Delay Host Maintenance Mode = 30 seconds
- vCenter Server Appliance Shutdown Duration = 240 seconds
When a critical UPS event, such as On Battery occurs, the following
sequence is triggered.
- PowerChute reports
that the UPS is on battery.
- After the shutdown
delay configured for the On Battery event has elapsed, PowerChute
issues a command to turn off the Outlet Group and the Outlet Group
turn off starts.
- PowerChute starts
to shut down User VMs and vApps.
- After 2 minutes
(VM/vApp Shutdown Duration), PowerChute shuts down the vCenter Server
Appliance.
- After 240 seconds
(vCSA Shutdown Delay), PowerChute shuts down the HPE SimpliVity OmniStack
Virtual Controller.
- After 120 seconds
(OVC Shutdown Delay), the VMware Hosts enter maintenance mode and
are shut down sequentially if all VMs are powered off, otherwise
the maintenance mode task is cancelled. The delay between placing
each host into maintenance mode is the value set for Delay Maintenance
Mode (30 seconds). The PowerChute host is powered off last.
The Outlet
Group will turn off after the Power
Off Delay (configurable on the Configuration
– Outlet Group page in the
NMC user interface) has elapsed.
If registered with the Main Outlet
Group, the UPS will wait for any Switched Outlet Groups to turn off
before the Main Outlet Group turnoff starts.
If registered with a Switched Outlet
Group, only that delay is counted down.

(VM/vApp Shutdown Duration), PowerChute shuts down the HPE SimpliVity
OmniStack Virtual Controller.
- After 120 seconds
(OVC Shutdown Delay), PowerChute starts to execute the shutdown command
file.
- The VMware Hosts
enter maintenance mode and are shut down sequentially if all
VMs are powered off, otherwise the maintenance mode task is cancelled.
The delay between placing each host into maintenance mode is the value
set for Delay Maintenance Mode (30 seconds).
- An additional
70 second delay is counted down before the operating system starts
to shut down.
The Outlet
Group will turn off after the Power
Off Delay (configurable on the Configuration

off before the Main Outlet Group turnoff starts.
If registered with a Switched
Outlet Group, only that delay is counted down.
Recommended Power-Off Delays for Outlet Groups
By
default, the outlet group Power Off Delay
will be the same value as the Low Battery duration configured on the NMC.
PowerChute will automatically increase the Power Off Delay for the outlet
group it is registered with, if the total shutdown time it needs
is greater than the Power Off Delay.
The total shutdown time includes the following
values:
VM/vApp
Shutdown and Startup Duration
vCenter
Server Appliance Shutdown Duration
OmniStack
Virtual Controller Shutdown and Startup Duration
Delay
Host Maintenance Mode Duration
Execute
Command File after Host Shutdown delay
Shutdown
Command File Duration
SSH
Action Duration
Built-in delay of 2 minutes (this consists
of a 10 second OS shutdown delay and a 60 second OS shutdown
duration; rounded up)
 |
The time required to gracefully
shut down your operating system is not covered by the total shutdown
time, as PowerChute cannot determine how long it will take to
complete.
The
Power Off Delay for the outlet group should be long enough for
the OS to gracefully shut down. You should add extra time to allow
for unforeseen circumstances.
The
Low Battery Duration set on the NMC should be equal to or greater
than the Power Off Delay for the outlet group. |
