How to Perform a Password Recovery on BIG-IQ 6.1.0 VE

Hello! I'm in the process of deploying BIG-IQ in our environment and right now we have a Proof of Concept VM setup to test with. However, I forgot the password!

 

I have completed the following steps to recover the password, but haven't had any luck.

 

Reboot the system

Select proper boot version and press e to edit the options.

Scroll over the line that has "vmlinuz" in it.

Press e to edit that line and add "single" to the end.

Press b to boot.

Once a prompt appears type

mount -a passwd root

Enter new password twice

type reboot

However, once I reboot and get back to the normal login screen, I'm told that the password for root is still incorrect. I have tried this procedure a couple of times using different passwords and I get the same result.

 

I'm thinking the password recovery procedure might be different for BIG-IQ but haven't found any supporting documentation online that states that.

 

Any guidance regarding this would be super helpful!

Okay, I found a solution to this problem and I will post the steps below in case anyone else runs into trouble.

Sequence of events that worked for me:

  1. Reboot the system.
  2. Boot into single-user mode (same way as stated in initial question)
  3. Type "passwd root"
  4. Set the new passworld
  5. Type "mount -a"
  6. Now, instead of typing "restart" type "exit".

 

Once everything came back up I was able to sign in with the root password I just set and then I went ahead and changed the admin password as well.

you mention normal login screen, is that the webgui? if so, can you login with the root account on the CLI? and from there change the admin login?

Hello,

 

Sorry, I should have been more specific. When I reboot and get back to the login prompt at the CLI and try to log into root it states that the password is incorrect.

ah that is a shame, i never performed this on biq-iq, but on big-ip the method changed starting from 14.1, this might also be the case for big-iq, but not sure

Sadly this also does not work. I think I may have to start from scratch here. Thank you for your help!

last thing to make sure, you are booting in the bootslot which you selected to change the password on?
