  • 1.  Problem with HMC and server P5

    Hi,

    i'm having some wierd problem with one of my server P5 machines and i really need some help!

    i have a physical P5 machine which is managed by our HMC.
    right now, i have a problem with this machine cause looks like one network card is dead. AIX cannot startup when network is dead due to "Tcp/ip configuring" while booting, which cause the machine hangs on led 0581.
    i know how to solve this issue but in order to do so i need console!

    whenever i try to open a console from the HMC i get the error message "unable to open console, partition is in invalid state".

    so i tried to connect serial console using hyper terminal app from laptop but its refused to open a terminal.

    i've read that whenever server P5 is connected to an HMC its impossible to work with the serial Ports cause they are disabled. i've also tried to disconnect the HMC conncetion from this machine , shut it down and let her startup without managed by an HMC so perhaps the serial 1 port will work but it doesnt. i've tried with 9600 and 19200 speed and non of them works:(

    i have no other ideas of how can i open a console to this machine and enabled the second network card.

    Please, does anyone have any idea how to opena console from the HMC or direclty to the machine??
    tnx a lot

    Try shutting down the partition. While activating it, choose the virtual console option (check box) so that the console window is open right from the startup. Then you can bootup into maintenance mode to fix the issue.

    The 581 code should also finally time-out. I have had the same 'hang' situation when the default router is down and DNS is timing out during startup. This is one of the reasons I always set my /etc/netsvc.conf to have the line:
    hosts=local4,bind4
    Note: the added 4 is to use only IPv4. You may specify without a number and I believe the default is to try IPV4 first, then IPv6, then move to next source.

    Since you are using an HMC you should be able to open a virtual console regardless of the startup phase - and yes, this is the reason that once power is applied the console port no longer is active (with power off you should be able to access the ASMI interface. If you cannot your firmware is ancient!!! This was modified years ago to reactivate the serial port when the managed system is powered off.

    Hence, your comment that the HMC is not giving you a virtual console makes me wonder if there are not other things going wrong. Be sure to use the web-based ASMI interface to check the firmware error logs as well.

    good luck,
