/dev/[*]st* does not work with EXBAYTE 8505 with 2.6 kernels
I have just upgraded from RH9 Linux 2.4 to FC2 Linux 2.6 and now my EXABYTE 8505 no longer works.
If I try to access it with mt (using any device like nst0) I get no such device error message. Same thing with stinit.
The tape drive is found during boot, as this snippet from dmesg shows:
qla1280: QLA12160 found on PCI bus 1, dev 8

cat of /proc/scsi/scsi also shows the tape device:

lsmod seems to contain the necessary driver modules as well:

Any hints?
Please don't tell me that the 8505 is no longer supported.

This suggests that the st driver has not found your drive. Your tape drive is recognized as a sequential-access device and lsmod shows that st is loaded. Puzzling.
If you look at the kernel messages, do you see something like this:
st: Version 20040403, fixed bufsize 32768, s/g segs 256 Attached scsi tape st0 at scsi0, channel 0, id 5, lun 0
st0: try direct i/o: yes (alignment 512 B), max page reachable by HBA 268435455
Another thing to check is /sys/class/scsi_tape/. You should see these
files: nst0 nst0a nst0l nst0m st0 st0a st0l st0m

Any well-behaving drive is supported. I have used EXB8505 some years ago and I don't think this problem has anything to do with the drive.

Yes, I see this message in dmesg.

I have also used this drive for a year or two now. Initially with 2.4 I had problems with compression, but that was solved with new firmware that defaults to compression.
With 2.6 the tape drive fails to work with the Qlogic HBA's ISP1040 (the HBA simply doesn't work with 2.6) and QLA12160, but it works with the Symbios/LSI HBA.

OK, st has attached the drive.

So, the problem is specific to the Qlogic adapters. Do you see any SCSI error messages? (When st has attached the drive, the device should be present. If it is offlined by failing SCSI error recovery, the device disappears again.)

No, I see no error messages with QLA12160 HBA everything seems to be OK, except that I cannot access the device. I am able to access /proc/scsi/sg/device_strs and read the device string for the tape. As for the ISP1040 the qlogicisp driver simply prevents the system from mounting the root fs, even though the fs resides on an IDE disk. BTW. The QLA1260 is now being used in my PS with WIN98 and seem to work OK with a SCSI disk.
