I just noticed this:

[root at badserver ~]$ cat /sys/module/scsi_mod/max_luns
1

where on the one that works:

[root at goodserver ~]$ cat /sys/module/scsi_mod/max_luns
254


So with:

[root at badserver ~]$ grep scsi_mod /etc/modprobe.conf
options scsi_mod max_luns=254

remaking the initrd and rebooting, the option is not taking effect.

Any ideas?
