This section explains how to remotely control the power states of physical servers, VM hosts and VM guests.
In the RC console resource tree, right-click the desired server (or the physical OS or VM host running on the server) or VM guest, select [Power] from the popup menu, and select one of the following options:
This option powers on a halted resource and starts its operating system.
This option powers off an active resource after shutting down its operating system.
This option forcibly powers off an active resource without first shutting down its operating system.
This option restarts an active resource after shutting down its operating system.
This option forcibly restarts an active resource without first shutting down its operating system.
Click the <OK> button in the confirmation dialog displayed.
The specified power control operation is executed.
The progress of the specified operation is displayed in the Recent Operations area. Check that the operation status is shown as "completed", and that the resource in the resource tree or [Resource List] tab has changed to the expected power state.
Information
A reboot or forced reboot of a physical server or VM host is done by shutting down the server once, and powering on again (instead of a system reset).
Note
VM guests should be properly configured in order to use the power off or reboot options.
Attempting to power off or reboot a VM guest that wasn't properly configured will result in an error.
Refer to "A.2 Configuration Requirements" of the "ServerView Resource Coordinator VE Setup Guide" for details.
Depending on the server virtualization environment, a VM guest may automatically migrate to another VM host when being shut down. This may cause power control operations to fail and return an error when used on VM guests. Refer to "A.3 Functional Differences between Products" of the "ServerView Resource Coordinator VE Setup Guide" for details.
A VM guest can be configured to automatically start or stop whenever its VM host starts up or shuts down. This can be achieved by setting up the VM guest's startup and shutdown options in the server virtualization software used.
Refer to the virtualization software manual for details.
Take care of the following points when shutting down or rebooting a server running a Windows operating system.
If Windows is not configured to shut down when the computer's power button is pressed, the power operations in Resource Coordinator VE may not function properly.
To check this option, open [Control Panel]-[Power Options]. In the [Power Options Properties] dialog, click the [Advanced] tab, and check the action that is set to be performed when the computer's power button is pressed.
If a file is being edited by a logged-in user, a dialog prompting the user to save the file is displayed, and the system may not shut down immediately.
In such cases, shutdown does not take place until the user takes the appropriate action or a specified time (approximately five minutes) has elapsed.
Take care of the following points when powering-off or rebooting a VM host.
When using a server virtualization software's high-availability feature, confirm that the server is set to VM maintenance mode within that virtualization software. This can be confirmed from the virtualization software client.
Perform a power operation only after setting VM maintenance mode (either from the VM management software client or using the resource control command).
Refer to the server virtualization software manual, or to "3.2 rcxadm server" in the "ServerView Resource Coordinator VE Command Reference" for details.
Depending on the software virtualization product used, some restrictions may apply to the use of VM maintenance mode settings. Refer to "A.3 Functional Differences between Products" in the "ServerView Resource Coordinator VE Setup Guide" for details about such restrictions.
