1500 iLO 4 Configuration is temporarily unavailable (5)

We upgraded the iLO 4 firmware on a DL360p Gen8 with no errors or problems.  20 minutes later the server shutdown.  After booting back up, we get these errors at post:

iLO 4 not responding.  System Health Monitoring has been disabled

1500 iLO 4 configuration is temporarily unavailable (5).

After some analysis, the server appears to overheat and shuts down.  The top of the server is scalding hot.  My guess is that the iLO takes care of the server cooling, and now that it is broken, the server overheats.

Is there anyway to fix the iLO without a complete system board replacement?  I tried resetting the security dipswitch on the motherboard (setting switch 1 to ON),  and also removing the battery on the system board for several minutes allowing the BIOS and iLO to reset to defaults -neither of these worked.

Also I cannot even update the firmware of the server BIOS - it tells me it cannot communicate with the iLO sub-system and fails.  So in order to update the BIOS of a server, the iLO needs to be working?

Any suggestions?

Re: 1500 iLO 4 Configuration is temporarily unavailable (5)

  I've seen iLO becoming extremely busy and ROM reporting POST error 1500 when there is a corrupted AHS file that iLO4 cannot erase.   This issue was fixed in the new iLO4 2.40 but, the problem is how to land 2.40 on that box where iLO4 isn't responding at all.

One way to do this is by flashing iLO4 in direct mode.   Here are the steps:

1) Download the iLO4 2.40 Online ROM Flash Component for Linux ( CP027578.scexe )  :

2) Download the latest SPP ISO image and use the HP USB Key Creator Utility to make a bootable USB flash drive.

3) Copy the CP027578.scexe into the folder  /hp/swpackages  

4) Open the server hood, and turn on the iLO Security Override Switch on the system board (hood has a label showing the exact location of the Dip Switches)

5)  Boot Server into SPP, select Interactive mode and once it gets to the main menu, press ctl+alt+d+b+x to invoke the prompt.

6) Navigate to /hp/swpackages folder

7) Execute:  
       CP027578.scexe --direct     ( <-- notice the two dash characters before the word direct )

8) Once the iLO flash is complete, power Off the server, flip the iLO security override switch back to normal position.

Thanks, this helped me a lot. I was having the same issue. I had to fine tune some of the instructions so I will list them below.

6). To navigate to /hp/swpackages for me on SPP 2016.04.0 I used the path /mnt/boot/hp/swpackages

6a). Type su to become super user.

7). Execute with: ./CP027578.scexe --direct

You will likely need to stop the ilo service, but I can't recall the command, it will tell you what to do when you attempt the flash.

Hope this helps, thanks to Oscar Perez for putting these instructuions online, saved me a lot of downtime.
