Troubleshooting Set CPU or Set Memory Failed Tasks
An action task for Set CPU Count or Set Memory for VM has a Failed status in the recent task list because
power o is not allowed.
Problem
The Recent Tasks list indicates that a Set CPU Count, Set Memory, or Set CPU and Memory task has a status
of Failed. When you evaluate the Messages list for the selected task, you see this message.
Unable to perform action. Virtual Machine found
powered on, power off not allowed
When you increase memory or CPU count, you see this message.
Virtual Machine found powered on, power off not allowed, if hot add is
enabled the hotPlugLimit is exceeded
Cause
You submied the action to increase or decrease the CPU or memory value without selecting the Allow
Power  option. When you ran the action where a target object is currently powered on and where
Memory Hot Plug is not enabled for the target object in vCenter Server, the action fails.
Solution
1 Either enable Memory Hot Plug on your target virtual machines in vCenter Server or select Allow
Power  when you run the Set CPU Count, Set Memory, or Set CPU and Memory actions.
2 Check your hot plug limit in vCenter Server.
Troubleshooting Set CPU Count or Set Memory with Powered Off Allowed
A Set CPU Count, Set Memory, or a Set CPU Count and Set Memory action indicates that the action failed in
Recent Tasks.
Problem
When you run an action that changes the CPU count, the memory, or both, the action fails even though you
know that the Power O Allowed was selected, the virtual machine is running, and the VMware Tools are
installed and running.
Cause
The virtual machine should shut down the guest operating system before it powers o the virtual machine
to make the requested changes. The shut down process waits 120 seconds for a response from the target
virtual machine, and fails without making changes to the virtual machine.
Solution
1 Check the target virtual machine in vCenter Server to determine if it has jobs running that are delaying
the implementation of the action.
2 Retry the action from vRealize Operations Manager.
