Thanks, Mecki.   I think I've got it now.  A "drive" represents a physical
device, but "mount points" are related to the number in the mountlimit
parameter.  So I could have any number of drives designated for ADSM use, but
if my mountlimit was set to only 1 I would still only be able to access one
tape at a time.  Have I got that right?

Subject: Antwort: Difference between mount point & drive

Hi Betsy,

if you have a deviceclass of file you will only define a directory in that
deviceclass.

In that directory you might have up to 256 files that can be simultaneously
accessed
according to the mountlimit value of that deviceclass.

In this case a file is treated like a sequential volume - "mounted"

The Admin Guide in this case is really confusing cause a storage pool is
only working with
a deviceclass and there you might have a mountlimit of 1 or only one drive
in a library with a
mountlimit of drives.

For a copy process you will need enough mount points available - a drive
being used by another process is physically there but there's no mount
point available from that drive.

Hope this helps a little to understand why a mount point and a drive are
not the same.

Regards
     Mecki
