Known problem: Collecting an iLO license:
One of the steps in the checklist is to collect the iLO license. The following are known issues with
this step:
• You must be able to ping the iLO from the CMS using only the system name (not the fully
qualified domain name).
— The HP SIM License Manager uses the system name, not the fully qualified domain
name, regardless of system settings.
— Systems in the same DNS zone as the CMS will work fine.
— Systems in a different DNS zone will need to have the DNS suffix for the managed
nodes iLO added to the IP configuration of the CMS.
• You must be able to access the iLO via SSH from the CMS.
— The License Manager collects iLO licenses via SSH.
— There is a maximum of 2 concurrent SSH sessions for iLO.
— iLO SSH sessions may be abandoned and not reclaimed. This causes the iLO SSH to
deny new connections, and the License Manager iLO license collection to fail. If this
occurs, reset the iLO (that is, use the reset button at the bottom of the iLO diagnostics
page in the iLO web GUI).
Calibrating multiple systems at once
On the Visualization tab, select the check boxes to the left of the desired systems, and select
Configure→Calibrate Power (All Selected Systems) on the Virtualization Manager menu bar.
Procedure 5-94 Selecting a calibration option for multiple systems
1. Click the radio button to the left of the desired calibration option.
2. Supply values for idle and maximum power usage when manual calibration is selected. (See
“Power calibration calculations” (page 129) for assistance in determining valid values for
particular systems.)
Procedure 5-95 Confirming system selection
1. Review the list of systems in the Selected Systems table.
2. Optional: Click the remove link to delete a system from the table and remove it from the
calibration operation.
3. Select Apply or OK to set the new calibration value for all systems remaining in the table .
Want to calibrate a single system at a time?:
For each system in the Selected Systems table that you want to calibrate individually, click the
details link to open the Calibrate Power (Single System) screen for that system.
TIP: If you elect to individually calibrate some of the systems in a multiple listing, but not all,
first calibrate the individual systems, and then remove them from the Selected Systems table.
The systems remaining in the table list are those to which you can apply a different set of values
at once using the control buttons on this screen.
Calibrating power within a scenario
This screen allows you to define the power calibration parameters for simulated systems in a
scenario. These power settings specify whether or not to calibrate power, and if so, which settings
to use for the calibration.
