Trouble getting serial access to iLO working

[Matthew Braithwaite_1]

On my DL380 with RedHat 7.3, I've installed the latest hprsm and I've been able to configure the iLO using `hponcfg'. In particular I have been able to set:





but hitting ESC ( on the serial port doesn't get iLO's attention, as I think it should, from reading the manual.

I have BIOS serial redirection turned on, and Linux is also using the serial port. I don't know if this makes a difference. What I want is to interrupt Linux's use of the serial port to get iLO's attention. You know, like on a Sun. :-)

I hope there is a way to do this without rebooting, since I'd like to do it on 500 machines. I'm pretty pleased that I was able to get this far (upgrading hpasm, firmware upgrade of iLO, reconfigure iLO) without a reboot!

The serial access to iLO is disabled on DL380G3 hosts with CPUs slower than 3.06GHz (533MHz front side bus). This is to prevent a possible host lockup when using "esc (" to get iLO's attention.

It sounds like you are doing everything right. Please try it on a host with 533Mhz FSB (3.06Ghz +) or on a different server and let us know your results.

Thanks for the answer!

Unfortunately, of our ~550 DL380s, about 5 have CPUs 3.06 GHz or faster. So if you are correct I am screwed. :-(

Do you know whether this is a temporary condition that will be fixed in a future BIOS or iLO?

Unfortunately, the feature was disabled because a hardware problem was discovered. It cannot be fixed with a software update.

Well, HP officially confirmed what you've told me. (I opened a case with them around the same time as this thread.) Sigh. Oh well.
