Document Version Release Date Details 2 09/24/2018 Updated the Resolution with the permanent fix. 1 04/26/2018 Original Document Release. Any CPU utilization graph for HPE BL-series Gen10 Server Blades or Synergy Compute Modules will display incorrectly in the HPE OneView User Interface (UI). For instance, OneView will incorrectly display the utilization at 3% when the CPU is constant and will return a 70% or higher CPU utilization. In addition, the CPU speed may be shown incorrectly in OneView with zero (0) as its average speed: The issue will occur because the load average information for HPE Integrated Lights-Out 5 (iLO 5) with a Gen10 server or compute module will return in a different format that requires no processing or data conversion. However, with the older version of servers, such as Gen9 (or earlier) with iLO 4, the data requires a formula to calculate the average CPU utilization.
Any HPE Integrated Lights-Out 5 (iLO 5) with HPE Gen10 server or HPE Synergy Compute Module managed by HPE OneView 4.00.X or earlier versions.
This issue is fixed by upgrading to HPE OneView 4.00.11 (or later): https://h20392.www2.hpe.com/portal/swdepot/displayProductInfo.do?productNumber=Z7550-63180 Placing a Redfish API call directly to the HPE Integrated Lights-Out (iLO) for the server or compute module should return the correct values for its CPU utilization. Standard Windows will not include the Powershell commands listed here, OneView Powershell cmdlets will have to be downloaded and installed on Windows from the link in this advisory for these commands to function correctly: https://github.com/HewlettPackard/POSH-HPOneView/wiki Perform the following steps: Establish a login session.
