Power Management

Description

SUSE Manager allows you to power on, off and reboot systems (either physical or bare-metal) via the IPMI protocol.

Requirements

  • a fully patched SUSE Manager 2.1 server (see above for migration instructions from SUSE Manager 1.7);
  • one or more IPMI-enabled systems.

Configure power management

In order to use any power management functionality, IPMI configuration details must be added to SUSE Manager. To do that first select the target system on the Systems list, then select Provisioning -> Power Management. From the configuration page that is produced, edit all required fields (marked with a red asterisk) and click on Save.

Using power management

Systems can be powered on, off or rebooted from the configuration page via corresponding buttons. Note that any configuration change is also saved in the process.

The "Save and Get Status" button can also be used to query for the system's power state. If configuration details are correct, a row is displayed with the current power status ("on" or "off").

If a power management operation succeeds on a system, it will also be noted in its Event History tab.

System Set Manager support

SUSE Manager's power management functionalities can also be used from the System Set Manager to operate on multiple systems at the same time. Specifically, you can change power management configuration parameters or apply operations (power on, off, reboot) to multiple systems at once.

In order to do that, add systems to the System Set Manager as described in the System Set Manager chapter.

Then, click on Manage -> Provisioning -> Power Management Configuration to change one or more configuration parameters for all systems in the set. Note that any field left blank will not alter the configuration parameter in selected systems.

Once all configuration parameters are set correctly, click on Manage -> Provisioning -> Power Management Operations to power on, off or reboot systems from the set. Note that the Provisioning entitlement is required for non-bare metal systems.

In order to check that a power operation was executed correctly, click on System Set Manager -> Status from the left side menu, then click on the proper line in the list. This will display a new list with systems to which the operation was applied. In the event of errors which prevent correct execution, a brief message with an explanation will be displayed in the Note column.

Known Issues

  • This feature uses Cobbler power management, thus a Cobbler system record is automatically created at the first use if it does not exist already. In that case, the automatically created system record will not be bootable from the network and will reference a dummy image. This is needed because Cobbler does not currently support system records whithout profiles nor images.
  • the current implementation of Cobbler power management uses the fence-agent tools to support multiple protocols besides IPMI. Those are not supported by SUSE Manager but can be used by adding the fence agent names as a comma-separated list to the java.power_management.types configuration parameter.

More information on Cobbler power management can be found on the Cobbler Wiki.
