Hi,
it seems that your storage system announces itself as scsi-2 which has a maximum number of 7 luns/target.
I already use 15 luns with SPARC Solaris 9 from the same SAN. And "lsscsi -lv" shows "scsi_level=3" for all SAN-disks. Meanwhile I activate all LUNS with echo "scsi add-single-device $INST 0 $j $CNT" > /proc/scsi/scsi in a loop, this works ok.
If your storage system announces itself as scsi-3 more luns are scanned. your kernel parameters cannot work, because they don't apply to scsi_mod. Using scsi_mod is correct. Please have a look at /usr/src/linux/Documentation/kernel-paramters.txt.
Obviously this file is outdated, I read it already. It is for kernel 2.5.59, if one can believe at least its first line... "modprobe -p scsi_mod" shows the parameters "max_luns" and "max_report_luns". -- Viele Grüße ------------------------------------------------------------------------ Michael Behrens
