The simple answer is "no." The first schedule must run to completion before
the ADSM scheduler will kick off the second schedule, and then only if the
window for the second schedule is still available (so plan accordingly).

There are a couple of work-arounds that come to mind that you can try:

1) Register two node names for the machine and associate one with schedule A
   and the other with schedule B. Run two iterations of the ADSM scheduler.
   You may need to play around environment variable settings for one of the
   nodes if you need different dsm.opt files, or build a script to copy
   dsm.opt.A to dsm.opt and start the scheduler, then copy dsm.opt.B to dsm.opt
   and start the second scheduler. Or play around with the environment
   variables. Whatever works.

   The drawback here is that you'll have to use node A to restore or retrieve
   files backed up or archived by node A, and node B to restore or retrieve
   files backed up or archived by node B. This can be confusing.

2) Use a non-ADSM scheduler (like 'cron') to run whatever 'dsmc' commands you
   wish. This should allow you to run concurrent iterations of 'dsmc'.

   The drawback here is that you've got to develop a secondary scheme for
   scheduling ADSM events, and that complicates the tracking of said events.
