RE: gfs 5.1, rh 7.3, qlogic 2200, and a brocade

Hi

I've experienced the same problem with SuSE 7.3 and RH 7.3 with my =
qla2200 connecting to a Compaq HGS80.
At qlogic web site I found SANsurfer, an HBA administration software =
from which I can see my LUNs. This tells me that HSG80 and qla2200 are =
working well. But, cat /proc/partitions does not show the logical units =
and /var/log/messages only shows that qla2200 has discovered the HSG80 =
controller (LUN 0) but not the other LUNs.
Just yesterday I discovered where the error is: at SCSI support module. =
It seems like each LUN discovered tells the kernel wether it needs to =
continue looking for LUNs or not. For any reason, the HSG80 controller =
says that no more LUNs need to be discovered.
I've hacked the SCSI support module in this way:
Edit file /usr/src/linux/drivers/scsi/scsi_scan.c
Search the 'break' in function scan_scsis
Comment it.
Recompile the kernel as usual

Other issues:
Same hardware with RH 7.0, I see the LUNs.
HSG80 + HBA Emulex + SuSE 7.3, I see the LUNs without hacking.

I hope this helps (I'm a little sure this will help you)
good luck

oh, i haven't even gotten that far. i mean when i do a
cat /proc/partitions, only the internal drive shows
up.
