IBM has replaced all parts in the system 3 times. Had electrician check to make sure the dedicated electrical circuit was good. Made sure the server rack was grounded, but AIX keeps shutting down when everyone is on the system. Reloaded AIX on the system. If the system is left alone it will stay up.
Does anyone have any ideas of what I can search for to locate what is causing this issue?
The errpt -a command only shows that there was electrical failure. I have had the electricians come in the our building and check the dedicated circuit we have, plus there is a APC 1500 UPS that the system is plugged into. IBM has been in to replace every part 3 times, plus two different servers.
is the UPS OK? is there any situation that the UPS goes into overload conditions temporarily (i.e., 4 servers normally attached but additional server attached for testing)? i had a server reboot at "fun" times because the UPS that was feeding it power kept power-cycling ... problem fixed when UPS was replaced ...
as an added measure --- if the server has 2 power supplies --- attach 1 power supply to the UPS and the other 1 to another UPS that is attached to a different circuit ... if you don't have a second UPS --- attach the 2nd power cord directly to the circuit ... this should eliminate more than a few power issues as the power supply will still be operational as long as either UPS is functional in a 2 UPS setup or as long as either the UPS or the direct circuit conmnection could still supply power in a UPS-direct setup ...
I wonder string constant exists permanently or temporary.
For example,
printf("hello, world");
the function printf access to it is through a pointer. Does it mean storage is allocated for the string constant to exist permanently in memory? :confused: (4 Replies)

Hi. My server was running fine for a couple of months. When the building power system needs to be maintained, we had to shutdown all servers, then my AIX server just didnt want to start at all.
When it reaches the "Welcome to AIX" screen, it reboots again :(
Could anyone have any idea what it... (2 Replies)
Anyone faced this?
I rebooted the HMC through command line after patch installation (hmcshutdown -t now -r)
The strange thing happened was the hmc never rebooted, I was not able to connect it through graphical view or through ssh, but the session through which i issued the command was still... (4 Replies)
I'm not sure how to best explain what I'd like to do, so let me give an example. I used to work in a department that deals with internet security. This department had an "internal" website (only people in the building can get on it) and an "external" website (anyone in the world can get on it --... (1 Reply)
Hi,
I've got a bunch of IBM AIX 5L 5.3 and 5L 5.2 servers here that I've inherited from my predecessor in a new job, and I'm trying to sort out their timezones. A number of them need to have their timezones changed to the correct setting - it would appear that they were not configured properly... (2 Replies)
When I do a hard reboot, the system recognizes both the ttya and the ttyb, but when I do a hard reboot, it only doesn't recognize the ttyb. Is there a way I can fix this???
Thanks!:confused: (5 Replies)
