Copy the DSM.OPT created by the GUI or by the BackBox installer to the
directory created for the VT Controller:
(C:\Program Files\tivoli\tsm\baclient) or
(C:\Program Files\ETINET\Virtual Tape Controller\Config\Samples\dsm.opt)
Use any text editor to finalize DSM.OPT
Verify the value of these keywords:

Specifying NODENAME and PASSWORD in LAN-free configuration
This alternative must be used when there are several VTCs accessing the same TSM
data storage in a LAN-free configuration.
Each VTC must connect by using a distinct NODENAME/PASSWORD and share access
to the virtual volume data by specifying a distinct target node (ASNODENAME) that
will own the TSM data whatever the connecting VTC.
Each VTC must specify a different NODENAME in its DSM.OPT. The ASNODENAME
must be the same in all VTC attached to the same Domain.
PASSWORD can be specified in the DSM.OPT file, or set in the MS-Windows registry
by using PASSWORD ACCESS GENERATE (refer to the TSM documentation).
