VSE Management 4.0: Identifying the UP Clock Error

On Dual Core Intel® Itanium® 2 processors running HP-UX 11i v2 (11.23), Capacity Advisor’s data collection mechanism (the Utilization Provider) may use the wrong clock speed for the system. Systems running HP-UX 11i v3 (11.31) are not affected. Systems using Utilization Provider version A.01.06.02 or later are not affected, provided that patch PHKL_33752 is installed. For affected systems, the magnitude of all reported CPU data is incorrect but can be corrected. Capacity Advisor will show the clock speed of such systems as approximately 400 MHz when it should be approximately 1.6 GHz. This causes the default scaling of CPU data in What-If scenarios moving a workload to or from an affected system to be off by approximately a factor of 4.

Managed nodes will have this problem if they are:

	NOTE: The correct clock speed is reported for VM guests, even if clock speed reported for the VM host is incorrect due to this problem.

	Identifying Systems with the Utilization Provider Problem Using Capacity Advisor

You can identify systems with this problem by checking the CPU Allocation column on the Edit Scenario page in Capacity Advisor. The same information is available in the Profile Viewer if you are using Capacity Advisor 3.0.
