ESXi 5.1 CPU Utilization at peak 100% Post update

Hi All,

I just did esxi 5.1 patch update and what i see post update all the host in the cluster is taking 100% CPU utilization.

Before update - ESXi 5.1.0 2323236

After Update - ESXi 5.1.0 2583090

Dell PowerEdge R720

BIOS Version - 2.4.3

Firmware version - 1.66.65 (Build 07)

when i see the VM's utilization, VM is not at all using the memory and CPU only the host shows as 100%.

Am i missing some thing , post patching is this kind of bug. does any one faced similar issue.

Thanks a ton in Advance

Ensure your system's IPMI firmware and/or system BIOS has been updated to the latest available.  My system's high CPU usage issues were resolved due to outdated IPMI firmware on my system board.  Once updated, I haven't had an issue.


'ps -T' I  'vmklinux_9:ipmi_thread'. is it 100% then do ipmitool to reset the system process using command pmitool -H ilo_ip -U admin -P ilopassword from Linux box.



If you find any answer useful. please mark the answer as correct or helpful.

Hi,

looks like the commandline posted above is for a HP iLo card, not sure if it will work with a DELL system. First of all try to update the DRAC firmware and check for further updates (BIOS, firmware etc.) on DELL support pages for your server model.
