Tandberg SLR4 loader makes SCSI ASC-39160-MAC disappear. How do I access a Scsi tape autoloader?

[Michele Marie Dalene]

I am trying to use this on my PowerMac G5 using Os X Leopard. I connected my Tandberg SLR5 unit with a asc-39160-mac to the narrow 50 pin cable. The tape drive makes the scsi card disappear!. The same drive on a Linux x86 box works fine and s recognized. That card is a AHA-2940UW however.

The same connection is used for my Microtek X6el scanner with no problem. I don't know if the driver was compiled for power-pc or not. Nor can I find the source so recompile it for power-pc if it is not released as a Power-Pc code.

In short, I don't know where the problem. is it because the tape drive is a Scsi-2 narrow device of less than 5MB/s or is it your driver?

I am buying a Dell Powervault 110T VS80 drive in June and I would like to use it on all of my machines for backups.

Also. How do I use a Scsi tape changer on the Mac? I thought I would ask since I have two systems on my wish list. a Powervault 122T VS80 with bar code reader and a Dell Powervault 120t DLT1 unit. is compiling MTX on the mac even possible? does it support the Scsi Generic devices like it does on Linux.

Yes, I have Debian-PPC in another partition on this machine but I would like to do it native, if possible.

I await your reply.

Thanks

I'm curious what you mean by "disappear"? As in - it doesn't show up in system profiler? The device should show up in the IO registry regardless of whether IOSCSITape is loaded. So I would take a look at that first. I'd start here both before and after IOSCSITape is installed:

As it seems you already know tape changer/library support just isn't there yet in IOSCSITape: no SCSI code nor mtx component. Perhaps some day.

Sure it's possible, just takes time to implement. :)

I hope that helps and thanks!

I think the disappear was do to that I had forgotten to remove the passive terminators, on the drive,  before putting it in an external case. I found the manual from tandberg online after I wrote that. So in short I had THREE terminators and my scsi bus was not happy. 
 

I have not tried it since I put the drive into my pentium 4 Linux machine.

Right now, an update, My new Powervault 122T VS80 is seen by Profiler but I cannot get the Kext to load up. Was this compiled for Intel? I have checked in troubleshooting and it does not show up in any way. Here is what profile shows.
SCSI Parallel Domain 65536:

  Initiator Identifier:    7

BNCHMARK VS640:

  Manufacturer:    BNCHMARK
  Model:    VS640
  Revision:    5639
  SCSI Target Identifier:    5
  SCSI Logical Unit Identifier:    0

BNCHMARK VS640:

  Manufacturer:    BNCHMARK
  Model:    VS640
  Revision:    5639
  SCSI Target Identifier:    5
  SCSI Logical Unit Identifier:    1

But looking for Kext shows nothing. I am using OSX 10.5.8 running on

Dual 2GHZ PowerPc G5

4 GB DDR sdram

I do not see any IOSCSITape anywhere even from the Command line!

How do I compile this driver? I looked at the source and I did not see a Makefile. Nor, do I know what the hg command to get the file from the repository is. I know cvs and I am somewhat familiar with GIT but I know nothing of hg.

looking at your mt comand shows:
bash: /usr/local/bin/mt: Bad CPU type in executable
bash-3.2# file /usr/local/bin/mt
/usr/local/bin/mt: Mach-O universal binary with 2 architectures
/usr/local/bin/mt (for architecture x86_64):    Mach-O 64-bit executable x86_64
/usr/local/bin/mt (for architecture i386):    Mach-O executable i386

Clearly, you compile for Intel and I need to know how to recompile the Kext and the /usr/local/bin/mt command for PowerPc. I have Xcode installed.

The extension did not even install in the /System/Library/Extensions folder.

How can I fix that?

Your help is appreciated.
