Issue with ILO and fan


Recommended Posts



Lately my Microserver gen8 has started acting weired. Every five minutes or so the fan starts running at max speed. I tried logging into ILO but page seemes not loading from time to time. Sometimes I get message "Connection with iLO cannot be established. If you recently made changes to the network configurations, you may need to refresh this page to re-negotiate an SSL connection."

If I´m able to connect to ILO I will be disconnected from time to time. Seems to be related in time where the fan starts to go in max speed. The eventlog for ILO has many "ILO reset by watchdog".

I have tried changing the switch on the systemboard of switch/jumper 1,5 and 6 to on for resetting NVRAM and ILO. Does not solve anything.


Trying getting a AHS but that gives me error

"AHS Data is unavailable due to a file system issue. If the iLO has been recently reset wait a few minutes and then press the Refresh button at the bottom of this page to reload."



Anyone else with this issue? Do I have to change systemboard?



Logs on the ILO:

AHS Data is unavailable due to a file system issue. If the iLO has been recently reset wait a few minutes and then press the Refresh button at the bottom of this page to reload.

I'm sorry to resurrect this old thread, but I'm having the exact same issue! And it seems to happen more and more frequently. It started a couple of days ago with the fans speeding up maybe one or two times a day. Now it's happening almost every 2 minutes.


Did you discover the reason for this? Did you find any solution?
