There is a bug with the AIX adsm scheduler, as silly as this sounds, this is 
what works:

/usr/lpp/adsm/bin/dsmc sched 1>/dev/null </dev/null

    We recently began using adsm with the server on an IBM RS6000
    box.  Now I have a fundamental question:

    To restart the client portion of adsm, the manual says to
    include the following line in /etc/inittab:

     adsm::once:/usr/lpp/adsm/bin/dsmc sched > /dev/null 2>&1

    However, when we reboot, this doesn't seem to work. The backups
    will not commence unless I manually issue the 'dsmc sched' command.

    Any ideas?

    Thanks.
