How to configure a device file for 2/20 library with fibre channel?

I have a similar question that I have seen before but really have??nt got any answer on.
How do I configure the HP Surestore E Tape Library 2/20 to my L-Class server connected through Fibre channel cable. With the command ioscan -fn it looks like this.
ext_bus 5 0/7/0/0.8.0.255.7 fcpdev CLAIMED INTERFACE FCP Device Interface.
This system is installed and configured by HP and I shall install omniback II 4.0.
The device file that are created is named /dev/scsi/tapelib and looks like this (ll /dev/scsi):
crw-rw-rw- 1 root sys 203 0x050000 Oct 3 11:52 tapelib
When I try to test the library with mc I got "no such device or address". If I configure a device in Omniback using this device file I can??t scan tape or do backups, I got the same kind of error message.
My question: Is the device file different if the library is connected throught fibre instead of scsi. Is my device file correct.

Best Regards
Bro

Download the latest patch PHKL_25675 or replacing patch PHKL_22759 if you have it.

Thank you all for your respons. It now works fine.
The problem was the device file. When I changed it from 0x050000 to 0x05b000 it start working.
The output from ioscan was:
unknown -1 0/7/0/0.8.0.255.7.11.0 UNCLAIMED UNKNOWN HP C7200.
If you translate 11.0 to hex you got b0 instead of 00 in my original device file.
