[SOLVED] SCSI not working

Message

ayleid96 · Post by **ayleid96** » Sat Apr 30, 2016 7:15 pm

Hi,

I have old Symbios Logic 53c875 SCSI controller and i wanted to test some of my scsi drives.. i recompilled the kernel for scsi support and for for that specific controller... still, the module doesn't show up in lsmod and i cannot find hdd in /dev/ ... fdisk -l only gives me the info for my two ata hdds but not for scsi, what should i do? thanks in advance

ayleid96,

Check the running kernel build date with

Code: Select all

uname -v

Are you actually using your new kernel?
If that looks good put your kernel config onto a pastebin site and past a link to it.

Make sure you driver is built and in use.
1/ lspci -k

Code: Select all

05:00.0 RAID bus controller: Adaptec AAC-RAID (rev 09)
	Subsystem: Adaptec 5405
	Kernel driver in use: aacraid <-- ok driver aaraid is use

2/ if point 1 is fine, dmesg should tell you the ending story (working, not working, missing firmware...)

Code: Select all

dmesg | grep aacraid -A8
...
[    0.530935] scsi host0: aacraid <---- ah fine we're good
...

kernel is ok, i know because i have to reinstall nvidia driver after kernel change...

btw why do i need raid drivers? this is my lspci:

you don't need any raid drivers, the aacraid is the driver name for my controller, it's a sample...
do lspci -k (note the -k behind it) and you'll get needed driver name for your SCSI controller.

ayleid96,

You have sym53c8xx built into your kernel. Its not a loadable module.
In menuconfig it will be <*>.

Both ways work. As its not a loadable module, it does not appear in lsmod.

ohh so thats it, but, what about hard drive? i dont see anything except sda and sdb (my two ata drives) in /dev/, also i see sg0, sg1, sg2 and i think that are hdd1, hdd2 and cdrom... any clues?

Is your SCSI drive connected properly? Jumpers set for valid SCSI ID? Cable terminated?

Post by **NeddySeagoon** » Sun May 01, 2016 7:14 pm

ayleid96,

scsi bus ... now there's a minefield as interesting as serial comms.

Do you have a device at each end of the cable?
Are both ends properly terminated (methods vary)?
Do all devices on the bus have unique scsi IDs, the scsi controller needs to have the highest used ID?

Do you have a 16 bit scsi bus or 8 bit - are you doing the mix and match properly?

Single ended or differential scsi?

krinn · Post by **krinn** » Sun May 01, 2016 8:03 pm

Make sure you don't have IDE_CORE set (device drivers, ATA/ATAPI... support)
Make sure you have BLK_DEV_SD set (device drivers, scsi device support, SCSI disk support)
Make sure you have BLK_DEV_SR (device drivers, scsi device support, SCSI CDROM support)

If your dev manager is running while deprecated support of ide is enable, it will be unable to create needed entries for your scsi devices.
the disk and cdrom appears as sg* devices because generic scsi is enable, so it's good news to see sg* entries.
That let me suppose your scsi card is in fact working, disks and cdrom detected. So it might either be that their support is not enable (fully), or that your dev manager have hard times with your kernel settings set.

i don't have IDE_CORE string in my .config but the other two BLK_DEV_SD and BLK_DEV_SR are set to "y"..

i think it's time for us to get more infos, what your dmesg is saying about your driver and emerge --info might help.

as your sg* devices are in fact your ata devices, that's not good finally.
you have no devices attach to your host0, check your card bios to see if it could see the disks, and as other said, check scsi connection (terminator set...).

Buffoon · Post by **Buffoon** » Mon May 02, 2016 12:30 pm

Easiest is to terminate one end of the cable using controller (ID 7 or 15) and plug the hard drive to the other end and use the jumper on hard drive to enable termination. In case your hard drive has no jumper for termination you need to use a terminator (Not Arnold).

It seems that some options are not set in bios of my scsi controller, i enabled "Scan on boot" option and now my bios can see hdd and my controller recognize it.. but now everytime i want to boot linux i get kernel panic... and when i disable "Scan on boot" everything is fine... D:

i disabled "Memory Handled IO" for SCSI in kernel and everything works fine now... that was causing kernel panics... thank you guys for your time, everything is good now my scsi hdd is now /dev/sdb as i removed older ata hdd.. thanks again
