Thanks, but I see issues with both of these methods:
1) Kicking off a script which then spawns the other two at
appropriate times:
a) doesn't solve the original problem of "if some
scheduled task is already running, this won't get started", and
b) the feedback about the success of the schedule won't
tell me if the filesystems got backed up.
2) Registering this machine as multiple nodes (and running two
schedulers) can create problems with identifying which 'node' has the
current version of the file for filesystem 'x'. I know I can also create
multiple include-exclude files and exclude from one what I include on the
other, but IMHO this is just plain silly and asking for trouble.
The client schedule piece of the code should be able to handle multiple
parallel requests.

The 'dsmc sched' mechanism behaved just like dsmcad with regard to
overlapping scheduled events.

I know of two ways to do this with 'dsmc sched'. One can use the central
scheduler to run a script that spawns child process to run two 'dsmc inc'
commands at appropriate times. I am reasonably sure this approach will
also work with dsmcad. Alternatively, one can register two node names
for the system, run a copy of the client scheduler process for each node
name, and set up a separate schedule for each node. This approach entails
creating two server stanzas in dsm.sys with an explicit nodename option
in at least one of the stanzas. It also entails using the -servername
option when starting at least one of client scheduler processes. I don't
know whether this second approach can be modified to work with dsmcad.
