Today I was alerted by vCenter with a yellow, “Host Storage Status” alarm.
Clicking the ESXi host in the alert I find from the description that I can check the Hardware Status tab of the host for more details
I see that the disk is failing and that RAID is in “Interim Recovery”. This doesn’t give me much information about the failing disk though. Maybe in HP ILO I can find more information? Nope, ILO doesn’t seem to have any information about the disks in the host. According to the ILO System Information, everything looks just fine.
I called to open a ticket with HP and while on the phone the support technician mentioned a diagnostic tool called HPACUCLI. If you installed your host a HP customized ESXi image, then this should be there for you.
SSH into your host then type cd opt\hp\hpacucli\bin. If you type ls you should see the script called “hpacucli”. Type ./hpacucli and then press “Enter”. You should see something about detecting controllers and you should be at a new prompt.
Type controller all diag file=/tmp/adu1.zip and then press “Enter”.
Now you will need a program like WinSCP that will get the newly created zip file off the host. Connect to the host with WinSCP and then navigate to the /tmp folder. Click on the adu1.zip file and the click “Download”.
Looking into the zip file we see four files; double click on “ADUReport.htm”. The report should open into your browser and should have a lot of information. Towards the top of my report I see that the drive has failed and if I scroll down I can actually get some in depth information about the drive. Things like the model and Serial.
