If you have a Cisco MDS 9000 and need to recover the password, start by booting it up. If it's currently running, type reload, otherwise power it on.
When you see the following lines, start typing CTRL+]
INIT: version 2.85 booting
This shows up after the initial BIOS screen on the console, about 15 seconds into the boot.
It might take a few seconds for it to do anything, just keep typing CTRL+]. You'll eventually get the following prompt:
Now enter config terminal mode and set the admin-password:
switch(boot)# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
switch(boot)(config)# admin-password ?
<WORD> Password for user admin (Max Size - 64)
Type in a complex enough password to get past the systems base requirement (in my case, 8 character minimum with upper/lower/special)
