Yes, long story. Lets not go into that!

Exactly! :-)

Well, whats the latest firmware? 3.01.04.75? Even thats dated Jun 2002.

Oops! Sorry, my mistake. I changed the module name in 1 place (to hide it!)
and not in the other. The name is the same.

Yes, I did build it when it was connected to another host and I just
attached it to this host.

Anyway, turns out my problem was the more than 8 luns per controller. I
edited /etc/default/rmparams to

System_MaxLunsPerController=32

and added targets to /kernel/drv/sd.conf

name="sd" class="scsi" target=5 lun=8;
name="sd" class="scsi" target=5 lun=9;

and also created /kernel/drv/glm.conf (as per the instructions in patch
109885-09)

# cat /kernel/drv/glm.conf

device-type-scsi-options-list =
"Symbios StorEDGE A1000", "lsi-scsi-options",
"Symbios StorEDGE A3000", "lsi-scsi-options",
"SYMBIOS RSM Array 2000", "lsi-scsi-options";
lsi-scsi-options = 0x407f8;

and did 'reboot -- -rv' and everything is working smoothly.

Thanks for your help.
