Do this, and your users will be unable to log into the webUI.Įven worse, do this to your root account, and you have now locked yourself out of the web interface. Do not create any passwords over 10 characters. So here is the first thing you need to know about adding users or changing passwords on the command line. Please note that you probably do not want to do this for several reasons.įirst off your users will be unable to connect to any serial ports and possibly be unable to log into the webUI at all. Since the Thinklogical Secure Console Server is running a variation of RedHat Linux, it is very tempting to try to add users via the command line using the useradd command as you normally would on a Linux machine.

Since Fan5 is also a bigun’ I decided to preemptively adjust its thresholds as well. Rather than increase the speed of the fan as I have seen others do, I decided to lower the thresholds for this fan with the command below. Slow enough to drop below the Lower Non-Critical Value threshold. # ipmitool -H 10.1.0.104 -U admin -P sdr listįan6 above is spinning mighty slow. Using the IPMIitool command from my Linux desktop first logged into IPMI controller on my systems and checked to make sure that the fans were actually working properly. Rinse and repeat a few dozen times and you hear what almost sounds like an intoxicated neighbor playing with his new weedeater.

Specifically what was happening was this… The systems were running cool, so the fans would spin down to a low rpm and the system would then throw a low rpm threshold alert and spin the fan back up.When this occurs the system switches into some sort of “Critical Cooling Mode” and spins all the fans up to 100% for a few seconds.

Or that one of my systems had sucked in a bit too much basement dirt and dust. At first I thought that maybe a fan was failing, and that one of my systems was overheating. On several occasions I have been working in my office and have heard the fans in my lab servers revving up and back down again. Sound wise this is a huge improvement over the stock 80mm fans used in the default enclosure as these larger fans can spin much slower than stock and still keep the system cool. Running my boards in these towers allowed me to use large 120mm and 140mm fans for cooling. When I set out to build my lab I decided to transfer my Supermicro X8DTI boards out of their stock rack mount enclosures (like what you see above) and into Standard EATX Towers. Likewise, the temperatures in my basement Homelab have been dipping below 66 degrees Fahrenheit, and apparently this makes my Supermicro Servers a bit unhappy.Ī bit of background. Its Winter here in the Atlanta area, and the temperatures have been dropping down close to freezing.
