Hi All,
Hoping someone will be able to help me with this problem - I
think I'm part of the way there already...
Running: Toshiba Laptop with Red Hat 6.2 - and have a HP Colorado 5GBe
external parallel port tape backup unit I *desperately* need to get
working (yes, I *am* a backup freak - a habit I got into in the days
when windoze was even *less* stable than it is today:-)
After checking out the parport website I got some of the information I
needed - about loading the paride driver, epat driver and pt driver -
and found that by manually doing a modprobe command for all three I was
able to get a response from the tape drive (i.e. it started accessing
the tape in the drive) - this is the most success I've had thus far:-)
When I try using 'insmod' for Paride I get the following messages:
/lib/modules/2.2.14-5.0/misc/paride.o: unresolved symbol
parport_enumerate_Rdcb625ab
/lib/modules/2.2.14-5.0/misc/paride.o: unresolved symbol
parport_claim_R46138e04
/lib/modules/2.2.14-5.0/misc/paride.o: unresolved symbol
parport_register_device_Ra78805aa
/lib/modules/2.2.14-5.0/misc/paride.o: unresolved symbol
parport_unregister_device_R857406d1
/lib/modules/2.2.14-5.0/misc/paride.o: unresolved symbol
parport_release_Re207d4f8
However, there is no problem loading it using MODPROBE...
ALSO: if I 'insmod parport' FIRST I don't get any of these error
messages...
After this, I am able to 'insmod' (or modprobe) EPAT okay, then PT - at
which point the tape drive starts to make some nice noises that sound
like I've actually got somewhere...
At this point, tail -f /var/log/messages reveals:
laptop Kernal: paride: version 1.04 installed
laptop Kernal: paride: epat registered as protocol 0
laptop Kernal: pt: pt version 1.04, major 96
laptop Kernal: parport0: PC-style at 0x378 [SPP,PS2]
laptop Kernal: parport0: no IEEE-1284 device present
laptop Kernal: pt0: Sharing parport0 at 0x378
laptop Kernal: pt0: epat 1.01, Shuttle EPAT chip c6 at 0x378, mode 2 (8
bit), delay 1
laptop Kernal: pt0: HP COLORADO 5GBe, master, RO, blocksize 512, 2458 MB
At this point I start thinking that I've made it - BUT, then I try to
use one of my backup programs (KDAT, Taper, etc.) to try and USE
/dev/pt0 as my backup device and nothing happens - although another tail
-f /var/log/messages reveals this:
laptop Kernal: pt0: Unimplemented ioctl 0x801c6d02
Someone on one of the lists I've been lurking on suggested that I needed
to actually MAKE the node '/dev/pt0' - so I tried this. Unfortunately,
running the 'mkd' script in the
/usr/src/linux-2.2.14/drivers/block/paride directory didn't work for me
- for each of the mknod command lines echoed to the screen I got a 'file
exists' error message...:-( So, the node had already been created...
FINALLY (after modifying my PT insmode line to read:
'insmod pt drive0=0x378,0'
- I got a RESULT:
I'm now at the point where one program (taper 6.9a) knows that I have a
backup unit there - but believes it is mounted in READ ONLY mode - and
comes up with errors whenever I try to do anything other than read the
tape (even reading is limited because I don't actually have a tape
formatted using this software to read:-( But at least it tries to do
SOMETHING:-))
I *know* there is something more I need to do - to get my tape drive
working - but DON'T know WHAT - HELP???:-)
I would also be grateful for ANY tips re: software to use with the tape
drive IF I get it working/etc. - I've had major problems trying to get
FTAPE/FTAPE-TOOLS to even RECOGNIZE the tape drive - and even simple
commands like: 'mt -f /dev/pt0 status' and so on come back with error
messages like '/dev/pt0' invalid argument'...
Many thanks in advance.
John Oliver.
