I've run into this issue too, but with just regular SCSI tape drives.
What happens if you do:
> sudo /lib/udev/scsi_id --replace-whitespace --whitelisted /dev/sg#
where /dev/sg#? Do your FC tape drives have /dev/sg# entries? What
is the output of:
> sudo lsscsi -g
and do you see the drives listed there?

/dev/sgX

You need to get the output of 'lsscsi -g' here...
Javier> I can't use /dev/tape/by-path, because these devices could change,

Here's what I use in /etc/udev/rules.d/dlt7k.rules file:
# Left drive in library - bacula uses it
KERNEL=="st*[0-9]",ENV{ID_SERIAL}=="SQUANTUM_DLT7000_CX752S1059", \
SYMLINK+="dlt7k-left"
KERNEL=="nst*[0-9]",ENV{ID_SERIAL}=="SQUANTUM_DLT7000_CX752S1059", \
SYMLINK+="dlt7k-left-nst"
#SUBSYSTEM=="scsi_generic", PROGRAM="/lib/udev/scsi_id --replace-whitespace
--whitelisted /dev/%k",
RESULT=="SQUANTUM_DLT7000_CX752S1059", SYMLINK="dlt7k-left"
# Right drive - not currently used by bacula
KERNEL=="st*[0-9]",ENV{ID_SERIAL}=="SQUANTUM_DLT7000_PXB09S0552", \
SYMLINK+="dlt7k-right"
KERNEL=="nst*[0-9]",ENV{ID_SERIAL}=="SQUANTUM_DLT7000_PXB09S0552", \
SYMLINK+="dlt7k-right-nst"
What you need to do is replace the ID_SERIAL match with the data you
get from the:
/lib/udev/scsi_id --replace-whitespace --whitelisted /dev/sg#
command.
Good luck!
