Fabric Interconnect booting to bash?

So, I thought I’d share an experience I had yesterday where my Cisco UCS Fabric Interconnect (FI) wasn’t feeling well and in my attempt to resurrect it, I seemed to break it even more. I’m sure that never happens to you…The FI was now booting to a bash prompt instead of the normal UCS console interface. It would get to the point where it would say “System is coming up….Please wait” and it would say this about 12 times and then display the bash prompt. I won’t bore you with what I actually did in my attempt to get beyond this, but lets just say I spent about 2 hours debugging it when the fix should have only taken about 5 minutes (hindsight is 20/20). It goes without saying that this situation should not happen under normal circumstances, but I’ve heard rumblings of people seeing this here and there after upgrading to 2.2.x. So if Google brought you here looking for a solution, you’re in luck.

All you need to do is:

bash# shutdown -r now

As the FI boots, press Ctrl + r to interrupt the boot process

loader>dir

Get the UCS kickstart file name – it would be preferable for you to boot the actual file name that the FI has in the /installables/switch folder which is the name of the kickstart image that you last installed. This can be found by looking at the working FI and running “scope firmware” and then “show image” (that’s from memory but I think that’s it). However, you can use the kickstart in the root if you can’t figure it out.

loader> boot ucs-6100-k9-kickstart.5.0.3.N2.<xyzabc>.bin

When the system comes up and sits are the boot prompt, run “erase configuration”

switch(boot)# erase configuration

That should do it. The FI needs to reboot and come back up as if it were brand new and ask to create/join the cluster.

Hope this saves someone some time.

  1. Hi Jeff,

    We’ve encountered this issue several times now, but I just found your post today. And sadly it did not work for us.

    bash-2.05b# erase configuration
    bash: erase: command not found

    How could you perform this action in the bash prompt?

  3. After doing the erase config and giving up all the required commands to start up new !!

    It agains goes back to bash shell ???

    is there a solution for this !

  4. Hi Jeff,

    Is there any good way of landing into bash once the system has booted?
    I want to clear up some space on the altflash partition that the FI mounts from the IOM.
    So far I managed to dump into bash into a very unofficial way but I wasn’t able to locate how to mount the altflash part (I also don’t have the required time).
    If you want to experiment or anyone is interested as a hobby (this won’t be available in any official manual or doc too soon probably):
    Connect to the Fabric Interconnect with a Console Cable and reboot.
    Press CTRL+R and end up in the bootloader.
    From there load the kickstart image.
    Then load the normal system image.
    While the system image is loading there is a “programming fault” with not stopping all the Linux signals from interfering with the process and by running a shell script to trigger the actual Cisco console.
    This shell script can be broken out of and one can land into bash as root.
    After you see the INIT prompt for Linux just press CTRL + Backslash and keep pressing it to kill the pseudo shell script until it gives up and dies (it has to be killed about 10-15 times).
    CTRL+C won’t work as I think SIG INT is being blocked from doing its things.
    SIG QUIT on the other hand (I am too lazy to google now and see if this is what CTRL+\ is sending) is allowed.
    Eventually you land into bash as root.
    Then you have to:
    – use sed and replace in /etc/passwd the nobash shell with /bin/bash
    – use echo to add a new line for root in /etc/shadow with a null password (this you will change upon login for the first time)
    – run the binary you killed with CTRL+\ so that the system continues its normal boot
    I ran it by hand and added a & at the end so that it runs in the background (I was afraid it might kill my newly activated shell console).
    It’s something with /isanboot/bin…
    If you look a bit throughout the system you’ll also find some Indian programmer names (a guy called Chandra that did parts of the linux binaries:) (same if you play with strings on some binaries).
    Also some interesting loopbacks used for communication and some internal 127 IPs to go with them.
    Same for all the block devices or flash in /dev.
    Some can be mounted..I had no patience to take it logically so I mounted all that was mountable in /mnt with a script.
    Now if you ssh as root or admin into the UCS you will land in a linux shell automatically.
    Just look in /etc/passwd and you will see for the user admin the shell that you have to start so that you get the classic Cisco command prompt.
    Starting it manually works perfect and you have access again to the nice frontend Cisco CLI instead of the backend Linux one (backend is though useful for those that are tech friendly enough to be curious what’s going on behind the curtains).
    My detective time has run out but if anyone discovers how the altflash can be mounted from the FI Linux, I would greatly appreciated (it has to be something either from /dev or via some protocol accessible via those 127 IPs that interconnect the various components).
    arp -an shows some IPs on the internal communication plane.

  5. Hi Jeff,

    I’m looking through your web page and am wondering if you have seem something like this… I posted this on the Cisco Community, but would definitely like to hear from you.
