Pcmcia
 

Please help..

I have a laptop with a Adaptec Slim SCSI card with a Sony SDT-D9000 attached and am unable to see the tape drive. Any assistance would be greatly appreciated...

what distro are you using?

If you do this (as root) what's the output?

1 - try "/etc/init.d/pcmcia status"
2 - try "cardctl status"
3 - try "cardctl ident"

This is to see if the problem is with PCMCIA itself or tape support (which I don't know a whole lot about).

Redhat 8

[root@ttop01 pcmcia]# /etc/init.d/pcmcia status
cardmgr is stopped

Ok that's a start (and I'm hoping someone with more experience can jump in here and help out better than I can :D ).

Mmmm. Not sure what to make of the message "cardmgr is stopped"...what happens if you type in "/etc/init.d/pcmcia restart" ?

Otherwise, PCMCIA seems to detect your card (I'm assuming the info displayed is correct) so at this point it would only be a question of loading the appropriate module (ie: modprobe modulename).

/etc/init.d/pcmcia restart stops and starts it fine but it never sees the tape drive that is attached to the PCMCIA card

Ok...well basically (I THINK) you need to find out what kernel module needs to be loaded for that tape drive (google is pretty good for this) then when you find out you need to try 2 things...

One you can load it manually (assuming the pcmcia is started) by doing this:

"modprobe modulenamehere"

if that works, then you can set it to load automatically by making the proper entry in /etc/modules.conf (at least that's the file in Mdk 9.2 which should be similar)

Sounds like you're on the right track tcaptian.... if the correst module is present, then (in theory) it should be loaded automatically upon inserting the card/connecting the device. You can look through /etc/pcmcia/scsi, /etc/pcmcia/scsi.opts for any potential clues on how these types of devices are treated.

I've recently been reading alot on the topic of PCMCIA use in Linux. (though I don't have any SCSI devices myself)
Here's some well-written documentation to help

http://www.ibiblio.org/pub/Linux/doc...WTO.html#ss4.6

Though it's confusing that it is seen by cardctl and the module gets loaded, then it says it can't see the device.

update.

I just ran across this:

(from the article)that's not good news..

:( It is odd because somehow on an older kernel it worked - Thanks for the help.
