I hope it is showing like that because My blade server has two hba
cards and I have done zonning of tape for both of them.

I got serial number and respective indexes from My IBM tape's
management console. Thanks for information.
for naming persistence I have configured below rules in
/etc/udev/rules.d/98-st.rules file.
SUBSYSTEM=="scsi_tape", ID_SCSI_SERIAL=="000789XXXX1", SYMLINK+="st/st0"
SUBSYSTEM=="scsi_tape", ID_SCSI_SERIAL=="000789XXXX2", SYMLINK+="st/st1"
SUBSYSTEM=="scsi_tape", ID_SCSI_SERIAL=="000789XXXX3", SYMLINK+="st/st2"
SUBSYSTEM=="scsi_tape", ID_SCSI_SERIAL=="000789XXXX4", SYMLINK+="st/st3"
SUBSYSTEM=="scsi_generic", ID_SCSI_SERIAL=="00000782XXXX0401",
SYMLINK+="st/changer"
then I rebooted my system.
It creates all symlinks on specified place. :)
But still there is a issue all symlinks are pointing to a single
generic device.
