qlogicfc driver

[Roland Fehrenbacher]

Hi,

I am testing a SAN setup with a Fibre Channel RAID Controller (GMR) connected
to a QLA2200/QLA2100 via Gadzoox Cappelix Switches. The RAID controller
supports 32 LUNs on configurable SCSI target Ids. In the present case I have 3
RAID sets with pairs (SCSI Id, LUN) (0, 0) (0, 1) (1, 0), i.e. two drives with
LUN 0 and one with LUN 1. While the controller itself sees all the 3 drives
when booting up, under Linux I am only able to see the LUN 0 drives.

Kernel is stock 2.4.6 using the qlogicfc driver. I also tried to set
max_scsi_luns=32, even though the default of 8 should be enough. No success.
Of course, support for multiple LUNs is enabled in the kernel. By the way,
using the beta driver on the qlogic site (qla2x00src-v4.27Beta.tgz) also
doesn't help. So the issue might not even be driver related.

Any ideas anyone?

Thanks.

Cheers,

Roland
