Never used IPMI in my life and while I thought it was cool when I heard about it, had no plans to. Just built a home server (while out of town) using a SUPERMICRO MBD-X10SLM+-F-O I put an nVidia 405 based video card in it but it may be bad. When I power it on, I get some beeps but they are different than the no memory beeps (I intentionally powered on w/o memory to hear those) and I think what may be happening is normal boot process but no video simply because the card (bought used) may be bad. Before I go and try to find a retailer that still carries VGA cables, is there a way via the boards IPMI interface (it has ethernet port just for that) to connect from my CentOS 7 laptop and see if the machine is normally powering on? I saw some IPMI packages exist for CentOS 7 but I don't know if this is what they are for. And it seems there are OpenIPMI and freeimpi packages. Are those just different ways of doing same thing or do they serve different purposes? Thanks. -- -=- Sent my from my laptop, may not be able to respond timely

And it is IMHO the best way to deal with servers. My normal server installing procedure is: 1. slap server wherever it will reside 2. Run the power cords 3. Run the ethernet cords for both normal use and IPMI. I'd probably be mindful of which vlans each cable goes to. 4. Fire computer up 5. Connect to the IPMI ethernet port using openipmi/whatever; by default it is generally setup to do dhcp. 6. Through ipmi, configure server's bios/raid/whatever and then boot it, feeding an ISO with the OS of choice through ipmi. Good time to do any server bios upgrade too. 7.

Whichever you use should provide a way to send out (remote) commands and then have a console so you can install thingies in the server. With that said, I have used openipmi myself; you do want the ipmitool, which is a package. Sample commands (lookup to see what they do. Notice I am using default l/p): ipmitool -I lan -H 192.168.21.125 -U ADMIN -P ADMIN sel ipmitool -I lanplus -H 192.168.21.125 -U ADMIN -P ADMIN mc reset cold ipmitool -I lanplus -H 192.168.21.112 -U ADMIN -P ADMIN mc info References I have used: http://wiki.hetzner.de/index.php/IPMI/en http://lists.us.dell.com/pipermail/linux-poweredge/2007-January/029190.html> Thanks. > > > > > -- > -=- > Sent my from my laptop, may not be able to respond timely > _______________________________________________ > CentOS mailing list > CentOS at centos.org > https://lists.centos.org/mailman/listinfo/centos

Don't forget to change IPMI PW!Okay if it requires DHCP this might be out, I'm currently out of town watching my brothers (various disabilities) while parents are on much needed vacation. Don't have easy physical access to the router, would have to take out stuff in front of it. Was hoping crossover ethernet would work.>> > Connect both to a switch attached to your dhcp server (or make > laptop provide that to ipmi) and then connect from laptop to ipmi and > go do your thing. > > Video cards are for desktops.Server room I agree, home server it really makes it easy to have several terminal windows open at same time and even launch a browser to troubleshoot something without needing to ssh in from another box.

Are those just > different ways of doing same thing or do they serve different purposes?the supermicro IPMI has a webserver, you can connect to it with a web browser, and can do remote console, remote media... the remote console requires java support in your web browser. -- john r pierce, recycling bits in santa cruz
