I don't know why TSM is too difficult to use with IBM 3607-16X Tape Autoloader. 
It make me under heavy stresses when setup the backup system for customer.
We use two device: IBM 20/40GB DDS4 Internal Tape (FRU: 24P2414) and IBM Tape 
Autoloader (P/N: 3607-16X) for backup with TSM 5.1.5.
The following is the result:
  a.. We can label and backup data into the DDS4 tape cartridge. 
  b.. We can't label tape cartridge in tape autoloader. It always shows 
message: "Unable to label volume xxxxx. The parameter is incorrect".
Although we install TSM 5.1.7 Patch to correct error IC36636 (The 5.1.5 TSM 
Server is unable to recognise the IBM 3607-16X Library) and enable Multiple LUN 
Support in SCSIselectUtility for using IBM 3607-16X.
We try install TSM 5.2 but the result is the same (TSM 5.2 Patch is not 
available now).
What the hell happened between TSM 5.1.5 and Tape Autoloader 3607-16X ???
Our configuration:
  a.. IBM xSeries 225 (P/N: 8647-3AX)   
  a.. IBM ServeRAID-4Lx Utra160 SCSI Controller (P/N: 06P5740) 
  a.. Wide Ultra 160 SCSI Adapter (P/N:19K4646)   
  a.. IBM Tape Autoloader (P/N: 3607-16x) 
  a.. IBM 20/40GB DDS4 Internal Tape (FRU: 24P2414)  
  a.. TSM 5.1.5 (license) and TSM 5.1.7 Patch 
  a.. Windows 2K Server, SP4
Does anyone can help me ?
Thanks in advanced,
