Why is a SCSI disk not showing up?

  • 772

I have a Seagate SCSI disk that is installed in my Kurwel 2500R sampler which I send files to via the computer. I had this system running on my Windows machine, but am not able to get it configured properly for Ubuntu 12.04

The SCSI disk is showing up in the BIOS, and in the Kurzweil, but I can't seem to get Ubuntu to see it. I have used GParted with no results. The SCSI drive is connected via a PCI slot in the computer.

lspci output for SCSI is: 

04:00.0 SCSI storage controller: Tekram Technology Co.,Ltd. TRM-S1040 (rev 01)

More information:

$ lsblk 
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT 
sda 8:0 0 74.5G 0 disk 
 ├─sda1 8:1 0 72.5G 0 part / 
 ├─sda2 8:2 0 1K 0 part 
 └─sda5 8:5 0 2G 0 part (in gparted this partition is unreadable)
 └─cryptswap1 (dm-0) 252:0 0 2G 0 crypt sdb 8:16 0 931.5G 0 disk 
 └─sdb1 8:17 0 931.5G 0 part /media/trunk sr0 11:0 1 621.1M 0 rom

(none of these drives seem to be the 4 gig SCSI drive which is a SEAGATE)

lsscsi outputs this:

[0:0:0:0] disk ATA WDC WD800JD-75MS 10.0 /dev/sda
[1:0:0:0] cd/dvd HL-DT-ST DVDRAM GH22NS50 TN00 /dev/sr0
[2:0:0:0] disk ATA Hitachi HDT72101 ST6O /dev/sdb
[4:0:6:0] process Kurzweil K2500 3.02 -

(the bottom is my Kurzweil where the drive is installed, but this is SCSI 7 and I need to access the DRIVE inside the Kurzweil which is SCSI 2)

I have recently discovered that the PCI card I use 04:00.0 SCSI storage controller: Tekram Technology Co.,Ltd. TRM-S1040 (rev 01) would need a driver.

After googling, I found this article:

http://ubuntuforums.org/showthread.php?t=1535201

I installed the package kernel-patch-tekram-dc3x5_1.41-2_all.deb, hoping that this would get UBUNTU to recognize my drive. After reboot still the drive is absent. Below is a description of the driver. I need to know if this is the right one for the kernel I have?

"DC3x5 is a SCSI host by Tekram which is not supported out of the box by the Linux kernel. This patch adds support for the card to the Linux kernel. The cards supported are DC315 and DC395, both based on the TRM-S1040 chipset. This package supports 2.2.20 & 2.4.18 kernels. Older and newer 2.2.x and 2.4.x should work too. It should also work and will attempt to apply to 2.5 and 2.0 kernel versions"

Looks like I have 3.11.0-18-generic kernel so this won't work.

Ideas?

    It looks to me like the driver should be available in newer kernels (under the name dc395x), but might not be activated/compiled by default. Does a sudo modprobe dc395x help? According to this, it is the right module for your card.

  2. There are a couple options you can try.

    1) Try obtaining a version of the kernel that you can patch. (Set up dual boot at you say Seth suggested in the comments) You can find versions of the kernel in the range your patch specifies here

    2) Migrate your Windows installation to Virtual box

    How to do either of these approaches is fully documented elsewhere and either approach triggers a different question which has likely been asked and answered long ago. I hesitate to create more duplication.
