View Full Version : Tape Drive Device

I have a Iomega Jaz, and a Compaq DLT (15/30) on an adaptec 2940 controller that used to be on my Linux box that I am trying to transplant to my G4 running the latest version of OS X. In the linux box, everything works flawlessly.

In MacOS X, the JAZ works fine, although when I run heavy I/O through it, the sound goes buggo -- in reality, any sound is completely useless...

Also, the BIGGER question is how do I create the /dev/nrst0 device so that I can back everything up using TAR or CPIO.

Are there any good OS/X based backup solutions that would take advantage of my hardware? Are any of them open-source or cheap. Since this is in my home, I really would like not to spend a lot of money on a solution.

after further investigation, i discovered that you should probably ignore this mknod business and see a later post about SCSI tape drives...


--
investigate...

% man mknod

MKNOD(1) FSF MKNOD(1)


NAME
mknod - make block or character special files
SYNOPSIS

re: backup solutions

Mike Bombich has some, and is working on incremental backup...

How do I determine the major and minor numbers?

this is a hint board, so you're gonna wanna send beer for that answer :D

not too very sure about this. i see some mentions about the system configuring itself at boot time.

have you plugged it into that SCSI card (at id 0) and looked in /dev for st0 or rmt0?

or perhaps i'm completely out in the weeds here, but i think those major and minor numbers are scsi bus (channel) and scsi id

when you refer to /dev/nrst0 , do you mean a non-rewinding tape drive?

gerard,

i can't find what i'm looking for about tape drive support on OSX, but i found some references to scsi tape drive on the boards at Dantz.com

http://support.dantz.com/ubbthreads/showflat.php?Cat=&Board=MACOSX&Number=364&page=&view=&sb=&o=&vc=1

i'm seeing noise about flakey scsi behavior, too.

i'll continue to look for "adding a scsi tape device to OSX" to see if i can find out how it's done.
