hi,

I have an IBM intellistation Z60 running redhat 7.3. I've installed an Adaptec 2940UW SCSI PCI card that will connect an external ExaByte Tape drive. Both the PC and Linux detect the new hardware on startup.
However, once in Linux I cannot see find any devices connected to this SCSI card. I've included a copy of my dmesg output below in the hope someone can find any problems. I noticed a modprobe error and I wonder if this points to a problem. Also, looking at the kernel config, SCSI support is enabled but SCSI Tape support and the low level driver for this of card (AIC7xxx) are not enabled.
Many thanks for any input.

Just a hunch but enabling the low-level drivers and the SCSI tape support would be in order here.

You may also want to post the SCSI section of your .config file.

AFAIK Linux should scan the scsi bus here (my adaptec 7880 and sym53c810 do) and report on the devices. So after making sure you have SCSI tape support either modularized or in the kernel verify termination.

thanks for the replies. I recompiled the kernel with SCSI TAPE support as a module and the tape drive works ok now.
