As Martin stated, it's going to be up to the software maker to tell you what you should have installed before you use their software. Some use the default Microsoft driver, some use the IBM driver from FixCentral, and others use their own that comes bundled with their software.
In the worst case, in Windows Device Manager, you should see either an "Unknown Device" or an "IBM ULTRIUM.." device. If you don't, you have a connection issue or need the driver for your FC HBA, which should also be under Device Manager, under Storage Controllers.
A good test is either to utilize your HBA's software suite or, if possible, use the BIOS access of the card during the systems POST to ensure you have a solid hardware handshake with the tape drive and that the two are communicating at a hardware level. If the hardware isn't talking to one another at a physical level, you won't go any farther.
