Red Hat Linux 8.0 SCSI Tekram DC305 Sun 811 (Segate st41600N) install problems

cgtueno · 07-08-2003, 03:16 AM

Hi !

Novice question.
Configuration :

Red Har Linux 8.0
Tekram DC305 Scsi Controller
Sun GWV811 External SCSI disk unit (Segate ST41600N)

Problem:
Installed the hardware.
How do I Install. configure, and access the disk.?
Note: Want to R/W data, not boot from the disk.
Booting from an IDE drive on the same machine.

Apologies :
A novice question.
Help would be greatly appreciated :-)

Its just a matter of figuring out what kernel module for the scsi card, and then formatting and mounting the drives. To figure out the card... and hence the module:

/sbin/lspci

Or, it might have already loaded it, what's loaded:

/sbin/lsmod

And, it might have scanned the drives, is there a section similar to this in:

dmesg

Code:

i91u: PCI Base=0xDC00, IRQ=11, BIOS=0xC8000, SCSI ID=7
i91u: Reset SCSI Bus ...
scsi0 : Initio INI-9X00U/UW SCSI device driver; Revision: 1.03g
  Vendor:           Model: CD-R/RW RW7060S   Rev: 1.30
  Type:   CD-ROM                             ANSI SCSI revision: 02
  Vendor: IBM       Model: DDRS-39130D       Rev: DC2A
  Type:   Direct-Access                      ANSI SCSI revision: 02
Attached scsi disk sda at scsi0, channel 0, id 8, lun 0
SCSI device sda: 17850000 512-byte hdwr sectors (9139 MB)
 sda: sda1 sda2

The last part is the partition scan, to zap what's there and create new partitions and such:

cfdisk /dev/sda

or

diskdruid

or, for the oldschool and bold:

fdisk /dev/sda

Then, once you've repartitioned them for "Linux", or possibly even "Linux SelfDetecting RAID" if you want to play with software RAID, its time to format them:

mkfs -t ext3 /dev/sda1

Or... ext2 or jfs or reiserfs or even xfs (but RedHat doesn't do that yet)

Then mount them, make some mount point somewhere:

mkdir /mnt/bob
mount /dev/sda1 /mnt/bob

Hi

From root :

I used lspci -vv to verify that the card is there. OK.
Qu. How do I figure out the module.

When I lsmod I cant see any module that I can identify as belonging to the SCSI card.

The module doesnt appear to have been loaded.
That tallies with dmesg. Which doesnt show any evidence of having scanned the disk.

I follow the process. Im just short on a couple of steps.

I cannot run diskdruid from an Xterm. (?)
I cannot find anywhere on the Gnome desktop.
I know that it was an available option when I did the oringinal install.

Thanks

Chris

Uhmmm... feed the output of lspci with regards to the controller into google.com/linux and/or just post the output here and I might even recognize it.

I have no idea where diskdruid is, the binary itself may be partly capitalized: DiskDruid maybe, RH does odd things. Offhand, it might not be installed by default and just be part of the installer... evil thing to do. If cfdisk isn't there, fdisk is perfectly usuable, a little archaic, but it does the job.

Cheers,

So I know the hadware is there !

Any ideas about which modules to install ? Sequence ?

Looked all over the place for diskdruid no luck !

I hope the weather is good over there.

Its cold here ! Brrrr !!!!!!!!!!!!!

Its probably one of three modules... I can't find much on google (or more to the point I'm finding too much on google) Try the following command, then check "dmesg" for a scsi ID scan, try each module... yes some of these will make the machine appear to hang, just give it about 20 seconds to recover from the scan. If a modprobe works... you should get no output.

/sbin/modprobe tmscsim

/sbin/modprobe sym53c8xx

One of those is probably it. If not, try back and I'll get really nosy.
