Operating Systems AIX Power5 9133-55A Serial Console connection issue Post 302966577 by Devyn on Saturday 13th of February 2016 05:19:07 PM

I set the speed using the below after powering the P5 down:

stty -F /dev/ttyUSB0 19200
stty -F /dev/ttyUSB0

Then connected via putty. Worked good. I had unplugged the HMC cables earlier while the system was running and that didn't make a difference. When I had established the console session, I plugged the power cables into the Power5 again and watched the messages:

S1>
You have logged out.
.....

It logged me out of the console ASMI. The thought that the HMC connection might disable the console port seamed like an odd thing to do to me so didn't consider to test it, even though it crossed my mind. I also tried to unplug the ethernet cables from the HMC ports to see if the serial ports would be reenabled but it doesnt' work in reverse. Once you power the Power5 server on or plug in the HMC cables, either action has the effect of permanently disabling the serial ports. Strange design but ok.

Hope this helps anyone else looking.

Cheers,
DH
