HSM is specifically designed NOT to use the nodename parameter because,
unlike backup, the data on the ADSM server is the REAL copy of the data,
and it must remain in-sync with the stub files on the local file system.
If you were to accidentally run a dsmreconcile, while the NODENAME
parameter was incorrect, we could very well expire data which is still
valid on the local file system.  To protect against this, HSM does not
honor the NODENAME parameter, and always uses the true system name.

The interesting thing is that we may need to relax this restriction when
we do HACMP support for HSM.

To answer your second question, the dls command will show the status of a
file.
