First of all the ADSM-Server has a list of nodes. When a client backs up
data the server does not know anything about driveletters but only looks
at the drive label. If a drive label occurs to be new, a new filespace
is created.

When you have to rename a drive label, you need to rename the filespace
within the ADSM server at the same time (at least before the next
scheduled incremental backup).

When you link to a drive through your LAN there are two reasons for ADSM
to decide that the filespace is new:
1. The Filesystem type is not NTFS but RMT-NTFS (don't know if this is
enough for getting a new filespace)
2. The system creates a new volume name by adding the drive letter it is
mounted to.
    e.g. you mount the drive labelled "APOLLO_D" to drive letter "F:"
and get a filespace name "APOLLO_D_F:" when backing up with ADSM.
