HP Capacity Advisor 7.2 User Guide

• Automatic power calibration can be done on managed ProLiant Linux systems with no additional
agents or providers.
• Automatic power calibration is supported for Integrity Linux systems when, in addition to the
agentless data collection, the Utilization Provider (UP) is configured on managed nodes running
supported Linux distributions. However, to obtain the UP, you must install it as part of the
Integrity Linux distribution or from a separate web download.
NOTE: The Utilization Provider does not support Integrity SUSE 11 or RHEL 5.5; these
Integrity Linux systems must be manually calibrated.
Automatic power calibration requires power metering support in server
Automatic power calibration with Capacity Advisor requires the power metering features of iLO
in the managed server. We recommend that you manually calibrate power for servers that do not
support iLO power metering.
For information about which servers support power metering, see Appendix A in the HP Insight
Management Support Matrix in the Insight Management Information Library.
No power metrics appear for simulated VMware DRS cluster
This situation occurs when VM hosts that have not yet been calibrated for power are added to a
VMware DRS cluster in a scenario. Suggested action:
1. Open the scenario change record (What-If Action→Undo/Edit/View Applied What-If Actions)
and delete from the cluster all VM hosts that were not previously calibrated. (See
“Undo/edit/review applied what-if actions in a scenario” (page 69) .)
2. From the scenario editor Systems tab, select the VM hosts that you want to calibrate, and then
select Edit→Calibrate Power (All Selected Systems). Calibrate the systems. (See “Calibrating
multiple systems at once” (page 89) .)
3. Add the calibrated VM hosts to the cluster by selecting What-If Action→Convert/Add to
VMware DRS Cluster. (See “Assigning VM hosts to a VMware DRS cluster in a scenario”
(page 76). )
Workload issues
Workload and system relationships may not match when comparing Capacity Advisor
and Matrix OE visualization information
A configuration change is not immediately visible in all Matrix OE components
This information is updated every five minutes, but there still can be a period of time when the
information that you can see in the Matrix OE Visualization tab may differ from that presented in
Capacity Advisor. Suggested action: Click to the Matrix OE Workload tab and then click the
"Refresh Data" link on the far right corner of the screen above the table that lists workloads
discovered by Systems Insight Manager.
HP SIM identification of a VM host and its virtual machines inconsistent
If you open the Capacity Advisor "Edit Scenario" screen and see this message:
Error generating screen.
Attempting to create second instance of
(Scenario_systemLayout_nameHeader_system_name_popupContent*)
this means that the HP SIM identification of a VM host is inconsistent with the identification of the
virtual machines associated with it. Suggested action: Re-identify the VM host and its virtual machines
to correct this issue. See the HP Systems Insight Manager Help to learn how to identify or discover
