Jacque,

Are you starting the ACSLS daemon that facilitates communications between TSM 
and ACSLS?
This is the code I put in my DSMSERV.RC script and I am having no issues.  This 
logic is executed before you start the TSM server.

acsdir="/opt/tivoli/tsm/devices/bin"                                            
                                                        
echo "Starting ACSLS daemon."                                                   
                      
cd $acsdir                                                             
./rc.acs_ssi quiet $* || "ACSLS Server (\"$acsdir\") error.. Aborting."
