So I was not having a good time with this supermicro box – it’s a 2U with 8 SATA drives (3T each), areca raid controller, 4 core intel, 8gb ram. Not much. It ran wonderfully as a FreeNAS\/NAS4Free box for the last 36 months and was just no being repurposed as an Oracle Playground (ie development\/POC).<\/p>\n
Installed CentOS 6.4 on it and gave it to the developer. Full building power outage later and it wasn’t booting backup. Turns out that my 8 drive RAID10 had some issues; 1 of the drives in a mirror died (click of death) and the other drive had corrupt data blocks. Awesome. Finding some working drives later, I rebuilt it again.<\/p>\n
Now it was Fan full throttle, fan not full throttle, random fan issues. The logs stated something like CPU Temperature assertion, CPU Temperature desertion. Overheating? The room temperature is a balmy 72F. So I put the fans on Heavy I\/O fan mode. This seemed to work for a few hours but then we were back to throttle up\/down again.<\/p>\n
I upgraded the IPMI firmware from 1.2.x to 3.0.x. I rebooted the machine. I even cold booted. I then updated the BIOS (download from supermicro, use Rufus<\/a> to create a new bootable USB device, copy files, run ami.bat BIOSNAME.FILE). Still no dice.<\/p>\n Then I read what user “SpeedKills” posted on a forum board; simply RESET the IPMI to factory defaults.<\/p>\n Did that and no more fan issues.<\/p>\n","protected":false},"excerpt":{"rendered":" So I was not having a good time with this supermicro box – it’s a 2U with 8 SATA drives (3T each), areca raid controller, 4 core intel, 8gb ram.
