my supermicro ipmi is still down
From when I upgraded the firmware back when that security thing made news. I haven't had time to go out on site to fix it.
The issue was upgrading the firmware required wiping all configuration from the ipmi controller as part of the upgrade process. Something that I don't recall ever happening with ILO or DRAC.
My IPMI wasn't behind a firewall mainly because it is a standalone 1U server in a colo with a single power outlet available to it. I have thought about putting in a soekris box with a power strip running off the colo's power strip (as long as it doesn't have a circuit breaker they say it's fine), but hasn't been a priority.
ILO 4 is just crazy good though, I love it anyway. Especially the integrated email alerting. Had a memory upgrade in a DL380Gen8 a few weeks ago and when the system powered up ILO emailed me that the memory was not installed correctly and it would not be used (wasn't aware there was a specific installation sequence required). Was able to look up the correct installation procedure and tell the on site tech to fix it.
"EVENT (14 Jul 21:27): POST Error: 207-Invalid Memory Configuration - Processor 1, DIMM 10 incorrectly installed. Please refer to Memory Population Rules in Documentation. This Memory will not be utilized."
And I love Advanced ECC(along with pre failure warranty - they replaced the memory chip no questions asked):
EVENT (13 Jul 05:18): Corrected Memory Error threshold exceeded ((Processor 2, Memory Module 12))
Also emails when NIC links go down, when the firmware is updated .. and the KVM remote console is crazy fast pretty much as good as being local. I think ILO4 has something like a dual core processor and 1GB of ram.
I've never personally had an ILO go unresponsive on me.
Though I do recall about 10 years ago at a company we had a network loop for a bit and it killed the redundant management interfaces on our HP Itanium systems. HP support said those modules were hot swappable so you could just yank them out of the chassis to reset them(regular reset methods did not work). We learned the hard way that they were in fact not hot swappable and it caused the systems to crash(well the first one we tried it on we obviously stopped after that one).
I liked ILO3 and ILO2 as well (though in some cases liked ILO2 more than 3).
