Configure Tape Library to be recognize by DPM

One of the users was having issue with the DPM (Data Protection Manager) backing up to tape library.  
Note : This tape library is using the Fiber-Channel Connection.  Therefore, the need from the Network Administrator to configure the zoning correctly in the SAN switch first.
For a start, I need to ensure that the Windows recognize the Tape Library.  After some troubleshooting, here are some findings :

Steps taken to resolve issue of tape library.
First step, I inserted the IP address into the Tape Library so that I can remotely http into the tape library.
From IE key in the  IP address, then login to the interface. 
On the Monitor Library (on the left hand side), drill down to Drive Identity.  Take note of the serial number as this information needs to be compared in the DPM.
