restart video card after boot of AIX 4.3

[jpn1]

I have 2 PH660's that both have video cards in them, they are each cabled to a KVM. The KVM died and since then have rebooted the servers, now that I have replaced the KVM I still don't have any video. I assume when the server starts up it checks to see if there is return signal on the video card from the monitor or KVM and if not doesn't bring that card up. So I rebooted 1 of the servers and its video comes up fine on the new KVM. I'm wondering is there a way to restart the video card for console output without restarting the whole server.

Haven't played with an LFT for years now but from memory the LFT uses the keyboard detection to decide whether to initalise the graphics adapter - why initalise the graphica if there is no direct attached keyboard being the reasoning I suppose.

You may get away with connecting the KVM / a keyboard and then running cfgmgr, or you may need to reboot to get it online the easy way once the keyboard is connected.

Depends on the type of KVM.
The older IBM kit needs a constant connection to the keyboard via the KVM

You are so correct, I have had 2 new KVM's in the frame and have rebooted 1 of the servers, the video will come up, but I keep filling the syslog and errpt with KBDD and LFTD errors.

Almost like the newer kvms don't output a constant signal voltage.

The old Apex Outlook that failed is really expensive though. I will crack the Apex open tonight and see if I can find some bad components to change.

I'm sure there is a less expensive 2 port PS2 KVM out there that will work with these old AIX servers.

Is it AIX that is looking for that constant? Or is the hardware outputing something and AIX is merely logging it.

I can stop all the Xservers, the DTlogin process, any process that looks like it might have something to do with the video. But it still keeps logging the error every few mins.

I dont know how to stop it.
