Pinned topic CSM rconsole no output on bladecenter H with JS43

‏2010-07-12T03:01:36Z |
My project have 3 bladecenter with 7 JS43 each.
After I install the csm software on a power 550 machine, I have define the node with the info get from lshwinfo.
when I went into the step
To test rconsole, issue the following:
rconsole -a

I found some rconsole window without any output and no login prompt,also there ware no error output,just only 2 line rconsole info
I check info on the AMM, the sol session is active with all nodes.
there is 2 node on bladecenter H one
2 node on bladecenter H one

    1 nodes in bladecenter 2
    3 nodes in bladecenter 3

    all nodes can be operate by the local KVM,but above node can't work properly with rconsole. So the NIM OS install with netboot can't going on.

    So , which can cause this problem and how can I debug the problem???

    Could you pls try to telnet AMM, then open console on AMM for one blade with problem?
    for example:

    telnet AMM
    console -T blade[3]

    To see if console on AMM works?

    I found this problem was relation to the js43 blade servers
    total 21 js43 blade servers,6 work with sol problem, 15 work OK
    when I replace the bad sol blade server with good one, the sol became OK too
    but the bad blade server don't have hardware error alerm.
    So ,which blade server problem can cause SOL work unproperly???

    I think your problem may be related to the blade console redirection. you can try:

    1. open blade its own KVM, and open console -T for a certain blade, for example, blade1
    2. reboot the blade to SMS, do "select console" in KVM
    3. you will see some words in console window, like "if you want to use this one as active console, press 0", then press 0 in the console window, not the KVM window. This is really important since it will make the SOL console as active one, and redirect all system output to this console.
    4. exit from SMS

    Then check whether your console has output on AMM, if console works, CSM rconsole will work too.

    Thanks

    Yes, U are right, your solution works
    And I found another interesting thing.
    The first node was installed factory,the rconsol to this node works fine.
    then I mksysb on this node and got a image file.
    I use nim to install other node with above image file, there is some thing odd.
    If I install one node and control the install procedure by the local kvm , after I install the node , the node reboot and I check the node by rconsole,
    found after the boot kernel info ,ther is no more rconsole output, even after the node compelete up and can operate by the local kvm.

    If I install other node and control the install procedure by the rconsole windows, after the node installation and reboot, rconsole work OK and got a login prompt.

    I check cons:0123456789:respawn:/usr/sbin/getty /dev/console is there on both nodes inittab file .

    So cames my question, Is it normal or is my configure problem ??? what's the different between this 2 installation?? Is any different between this 2 nodes after installation reboot?? very thanks

    This is normal case, during manual installation, nim will take the interactive console as the active console. If you control the install procedure from local kvm ,then nim will take local kvm as active console, if you control the install procedure from rconsole, then nim will take SOL as active console.

    We recommend you installing AIX with CSM and rconsole, then after installation, your rconsole will be set correctly and always work.

    Thanks.
