HP Capacity Advisor 7.2 User Guide

Known problem: Collecting an HP iLO license:
One of the steps in the checklist is to collect the HP iLO license. The following are known issues
with this step:
• You must be able to ping the HP iLO function from the CMS using only the system name (not
the fully qualified domain name).
◦ The Systems Insight Manager 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 node
HP iLO unit added to the IP configuration of the CMS.
• You must be able to access the HP iLO via SSH from the CMS.
◦ The License Manager collects HP iLO licenses via SSH.
◦ There is a maximum of two concurrent SSH sessions for an HP iLO unit.
◦ HP iLO SSH sessions may be abandoned and not reclaimed. This causes the HP iLO SSH
to deny new connections, and the License Manager HP iLO license collection to fail. If
this occurs, reset the HP iLO (that is, use the reset button at the bottom of the HP iLO
diagnostics page in the HP 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 menu bar.
Procedure 41 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 189) for assistance in determining valid values for
particular systems.)
Procedure 42 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 .
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.
