    Can I get into maint mode from hard drive or I will need an alternate
    media?

            go into maint mode, add an entry for root in /etc/passwd...
    ensure that system group is in /etc/system, ensure that login=true for
    root and then reboot. that will get you into the server to
    restore/rebuild the rest of the file.

                    I know just because I cannot get in and examined the
    script it ran. Script would result 0 /etc/passwd file. Too late though.

                                    Good morning everyone
                                    Now I've got a chance to practice AIX
    disaster recovery: one of the scripts smoked /etc/passwd file, to zero.
    Machine is micropartition, freshly installed but due to some reasons
    rebuild is not an option. Could you please advise how to I recover from
    this situation? (Way to boot to single user? Mount rootvg and restore
    passwd from other machine?)

                                    Thanks in advance

                                    Dmitry
