I have an HP Proliant ML110 G9 Server.

Added an HP Smart Array P420 PCI-E card to have real hardware RAID on the server. Everything works fine, but I noted that the P420's processor was extremely hot (I realized by touching the sink). Added an extra cooling and temperature seems to be ok now. I'm not using the HP cooling kit for PCI-E line, it's a home-made cooling solution.

The problem is that I cannot find a way to monitor the controller temperature.

  • HP ILO is not showing me information about P420 controller sensors.
  • Embedded HP SSA detects the controller well, but no shows temp readings.
  • Tried SSACLI utility with same results.
  • BIOS, ILO and P420 firmware are up to date.
  • Using the ssacli command ctrl slot=3 show I get this:

According to SSACLI official user guide that command should return temperature readings but is not doing it.

Any suggestion will be helpful

Thanx in advance!
