SCSI-CD-Writer don't show up

SCSI-CD-Writer don't show up

[Matthias Schniedermeyer]

#Include <hallo.h>



I have 3 SCSI-CD-Writers. "Strange" is that the boot-process only finds
the first one (1 0 5 0), the other two i have to add with

echo "scsi add-single-device 2 0 4 0" > /proc/scsi/scsi
echo "scsi add-single-device 2 0 6 0" > /proc/scsi/scsi

to make them useable.

Here is the complete ist of my SCSI-Devices:

I have a "Symbios 53c1010 (Dual Channel Ultra 160)" and a "NCR 810a" The
two devices which are not found are connected through adapters onto the
second channel of the Symbios 53c1010.

Kernel is 2.4.4 or 2.4.5ac6. 
As host-adapter-driver i use the "SYM53C8XX"-driver

If other info is needed, no problem. :-)

You should check if your devices are enabled for SCAN in the NVRAM.

Devices that aren't enabled for "SCAN AT BOOT" are forced by the driver to
fail the initial SCSI scan. As a plus, the driver also applies the boot
order for all Symbios HBAs that look Symbios-compatible regarding GPIO
pins and NVRAM layout.

For such subset of SCSI BUSes, this allows to present SCSI devices to the
kernel in the same order as BIOS saw them. On the other hand, this may
speed-up the system boot process a lot. If you had numerous O/Ses
installed on a single system, you would appreciate as useful it is. For
example, I use to boot an O/S with only drive 80 seen by BIOS and sda seen
by system, and then mount the other disks in the order I want.

  Gérard.

PS: See README.ncr53c8xx for the way to disable this feature if it does
    not fit your expectation. :)

<Sound of head hitting the table>

I had disabled all IDs from scanning (except those which had a drive) when
i first installed the system.

Now i enabled all IDs for scanning. :-)
