Ultra320 drive detected as narrow SCSI by adapter

Ultra320 drive detected as narrow SCSI by adapter

[Israel Mouton]

While my adapter card is scanning for devices, it detects my Maxtor Atlas V
as a narrow drive; however, it is an Ultra320.  This setup was working fine
until a few days ago, when adapter began detecting it as a narrow SCSI.  Now
the disk can only transfer at about 10-20MB/s.  My adapter card is an LSI
53C1030 and is PCI-X.  If any one can help, I will be extremely grateful.
I also included my dmesg concerning SCSI devices output below.

It's not doing domain validation, which configures the device ... that
could be a driver bug, but I know of no outstanding problems in that
area.

You can try to re-trigger it with 

echo 1 > /sys/class/spi_transport/target0:0:0/revalidate

and see what happens?

Thanks,

James

I don't seem to have a "/sys/class/spi_transport/" directory.  When the
system boots the LSI board detects it as a narrow.  I was wondering if it is
perhaps possible to reconfigure it under Linux at all?

Erm, what kernel is this?  The generic transport class, which does allow
you to configure this type of thing has been present in the kernel since
2.6.16

It is 2.6.16; however, it is the Debian version.  I did compile it from
source.  Perhaps there is a chance I left something unchecked I should have
compiled in?

If your using the driver having spi transport support,
it will be calling spi_dv_device from mptspi.c; can
you grep the source code?

If your using the older driver not having spi
transport support, then you are using a driver
where domain validation was implementing inside
the driver. In that case, I ask that you enable
the MPT_DEBUG_DV and MPT_DEBUG_NEGO from the driver
Makefile, and recompile, sending me the output.

In addition, if your having BIOS on your hba,
can you go into the bios configuration utilitity
and restore the defaults?
