/dev/? Where is my tape drive?

[civan93]

Hello,
I’m trying to figure out which /dev file my external scsi tape drive is connected

I have been having a bit of trouble getting my external tape drive to work with retrospect in os x server 10.2.

I have an adaptec 29160N card (now supported with driver 1.2)
Its connected to an external HP Dat40 dds-4

Retrospect cannot see the device.
Apple System Profiler [b:37b13e3fc0]can[/b:37b13e3fc0] see it at SCSI ID 3, Lun 0

When I do:
[code:1:37b13e3fc0]tar -c <folder to be archived>[/code:1:37b13e3fc0]
I get :
[code:1:37b13e3fc0]tar: Failed open to read on /dev/nrst0 <No such file or directory>[/code:1:37b13e3fc0]
Which makes sense, given there isn’t a /dev/nrst*

Any idea what /dev my tape drive is connected to, or better yet…any SCSI tool which can test the /dev ‘s and see if they are working?

Have you tried to look in the /Volumes/ Directory?

Unfortunately, tape drives dont’ mount like disc or optical storage drives. They can’t be accessed as a random storage media…since they are sequential.

Each SCSI device (actually each device) should be attached to some /dev/ device…but I can’t remember how to test to see which external device is attached to each /dev/ device. It seems like there was some simple way to check…

Any ideas on how to make retrospect see the device? both the hp tape drive and the adaptec card are on the approved list of devices. … but im sure the type of connection i have created is not approved…the external enclosure for the tape drive.

im starting to wonder if I really need that cdrom in the top bay. it seems external cdroms are much cheaper than external tape drives…
