password recovery mds9148

[jason.dewith]

Hello,

I am trying to follow the instructions here http://www.cisco.com/c/en/us/support/docs/storage-networking/mds-9000-series-multilayer-switches/29441-8.html

I reboot the switch, and before it extracts the boot image, I perform a ctrl - c (ctrl - j does nothing) which interrupts the and takes me to the  loader> prompt.  for the life of me I cannot get to the switch(boot)#  prompt  and perform the rest of the steps to reset the admin password.

I am using a serial connection with putty on windows 7 64.

Thanks for any insight

Try Fn+F6 or Ctrl+Fn and F6.

If that doesn't work, you can try Alt-b, which has always worked for me, however I haven't done a break sequence on a windows 7 machine.

Here is a link that points to a discussion on break sequences for a Windows 7 machine.

Below is a list of break key sequences, but I don't see Windows 7 listed.

Hi,

One option is ctrl-], (which didn't work for you) to get to the switch(boot)# prompt.

Another option is use ctrl-C to get to the loader> prompt, then run the kickstart to get to the switch(boot)# prompt.

Here is a video.

That's the secret sauce not listed in Cisco's documention!

To make it more specific:

1) CTRL-C immediately while it is booting, NOTE that CTRL-C is NOT the BREAK sequence. You should get a "loader" prompt:

  loader> 

2) run "dir" form loader> prompt and get the kickstart filename:

  loader> dir

    bootflash:

    16384 lost+found/
    4096 scripts/
    492 license_AMS15510216_9.lic
    6188 mts.log
    19983872 m9100-s3ek9-kickstart-mz.6.2.9a.bin
    73401580 m9100-s3ek9-mz.6.2.9a.bin

3) Boot the kickstart file, which should leave you in the switch(boot)#. If not, try sending a BREAK while the kickstart is booting.

  loader> boot m9100-s3ek9-kickstart-mz.6.2.9a.bin

    Booting bootflash:m9100-s3ek9-kickstart-mz.6.2.9a.bin ...

    ...

  switch(boot)#

4) Now you can run "conf t" and "admin-password xxxxxxx" to reset the admin password.
