Monitoring and Managing Server Power States
Power States
You can power on and power off a managed host by using this channel. Servers will be powered on, and if boot PROMs are configured, the servers will boot. Stopping a server initiates a graceful shutdown of the operating system and subsequent power-off of the managed server. If there is no operating system, you have to force a shutdown of the server. The following power states are displayed:
- On - The server is powered on and running.
- Standby - The server is powered off but still responsive to commands, for example, start and reset.
- Unknown - An error occurred while attempting to retrieve the power status of the hardware. The server is connected but does not returning any information on power status.
- Unreachable - The server cannot be contacted for information about its power state. This is most often caused by a network problem or the server is in the standby mode.

A manual network boot is required for OS-based or manually discovered servers. - To proceed with power on, click the OK button.
A job is submitted. - To view status of your job, click the Jobs Running section of the xVM Ops Center masthead.
