I have Slackware 10.1 with a compaq SCSI-controller recognized as "Unknown mass storage controller: Compaq Computer Corporation Smart-2/P RAID Controller", and an attached DDS2 tape drive. The latter, however, is not recognized. /proc/scsi/scsi shows no attached devices and neither /dev/tape nor /dev/st0 exist. I'm rather new to this whole SCSI thing so I'd apprieciate any help you can give me.
Thanks.

*edit* I'm using kernel 2.6.16.18, and the tape drive has a "TERMINATOR ON" jumper, which is on.

Hi,

I am sure you have appropriate kernel options. Also, do you find any suspicious output on syslog and/or message (dmesg)?

Happy Penguins!

I wouldn't know about kernel options, since I don't really know what I'm looking for. When searching in menuconfig for "tape" I found "SCSI tape drive support for Smart Array 5xxx", and that's enabled. The only relevant part of the dmesg output is this:
----
Compaq SMART2 Driver (v 2.6.0)
cpqarray: Device 0xae10 has been found at bus 2 dev 0 func 0
cpqarray: Finding drives on ida0 (SMART-2SL)
----

It doesn't seem to find any device attached to the controller

Hi,

One step ahead. Can 'lspci' or 'lshw' detect your hardware? (Also, check documentation in kernel.)

Happy Penguins!

lspci finds the SCSI controller: 02:00.0 Unknown mass storage controller: Compaq Computer Corporation Smart-2/P RAID Controller (rev 03)

lshw: command not found

Hi,

Probably, about 90% of chance, problem is "Unknown mass....". This should be recognized. However, I have my functioning network chip is recognized as unknown...

By the way, is anything attached to /dev/ida0 ?

Happy Penguins!

As far as I know, it's supposed to be recognized as Unknown. I'm sure I read that somewhere when installing the driver.

/dev/ida0 does not exist, /dev/ida/c0d0 does though.

Hi,

It seems nothing is attached to that device file. I am sure that you had no trouble when installing driver.

Usually "lshw" can give me (hopefully you) more info. You can find it at: http://sourceforge.net/project/showf...group_id=32683

Happy Penguins!

lshw reports this about the controller:

Nothing about a tape drive though.

Hi,

My penguin broke (I assume disk died..) so I am using the other penguin...

It seems that hardware is recognized as supposed to be, and cpqarray is attached. Can you find "cpqarray" somewhere else in lshw output?

I assume that your scsi is configured correct. check scsi part of lshw and driver is attached. Another good way is connect USB memory.

Happy Penguins!

Sorry about your penguin. Trust me, I know how it feels.

cpqarray doesn't show up anywhere else on the lshw output, and scsi doesn't actually show anywhere. Mounting a USB thumbdrive works fine though.

Hi,

Okey, now you have something to start.

I assume that your tape will be attached through scsi,
something like below should show up somewhere in lshw. (I am using 2.6.15, I think 2.6.16 is same. I heard that 2.6.18 is not, although it may be incorrect)
So that, problem is most likely at either scsi support, or cpqarray. As your USB stick goes well, scsi is likely to be okey...
I just checked sourceforge, and cpqarray is a kind of old...
Anyway, check these two...

It should not be difficult...

SCSI support is enabled in the kernel, and so is cpqarray. I'm gonna try to get a hold of another SCSI controller from a friend, and see if that works. Thanks for your help so far.
