Boot in Single-Mode
Hi All,
I have AIX 5.1 & I forgot the root password. I find out the solution is to boot in single-mode and remove the root password from the /etc/passwd file. My question is how to boot in single-mode? Also is there any password required when booting in this mode?

AIX Guides - a place to look.

And although it isn't detailed, see Forgot root password

Sadly this thread is the only one I could find for AIX as was assembling the faq on this subject. If you find a detailed procedure that works, please post it here and I'll add it to the faq.

Edit:

This excellent thread has been added to the FAQ! Thanks everyone.

Sorry for late respond, thanks for all. But I noted that the AIX CD is required. Actually I don't have the CD, so is there any possible solution doesn't require the AIX CD.

You need physical access to the machine to do the following:

1. switch off the machine

2. power on and enter the SMS menu

3. in the SMS menu there is a option called "Maintenance shell" or something such (I don't have an AIX machine at hand to try that out, but the option is named pretty intuitive).

4. varyon rootvg, mount /

5. edit /etc/passwd and /etc/security/passwd

6. boot normally
