AS 3 SCSI LUN problem with qla2300 driver

[Jin Zhao <jzhao qcorps com>]

I ran into a scsi lun problem after upgrade my system from as2.1 to as3. 
Our server was attached to a storage with 18 configured disk array via a 
QLA2342 HBA card. When it was as2.1 (from e-25 to e-49 kernels), the OS 
scsi layer can see and pick up all 0~17 LUNS. After upgrade to as3, with 
kernel 2.4.21-20.0.1EL, the OS can only see LUN from 0~7.

I also tried reconfiguring the HBA using SANsufer, all LUNS 0~17 can be 
seen there. I also tried other options such as failover, but it did not 
matter. I can add those additional devices manually by issuing, say echo 
"scsi add-single-device 2 0 0 8" >/proc/scsi/scsi, but that is painful 
solution from my point of view.

Has anybody run into the same situation before? Should I download the 
driver source from QLogic and build it instead of using the redhat driver?

Thansk,


Jin
