There are apparently several devices that return bad data for the REPORT_LUNS query, but do not return an error. The newer kernels only do sequential LUN scans if REPORT_LUNS fails. There may need to be a kernel option to force sequential scans.
There is. Try passing scsi_mod.default_dev_flags=0x40000 The SUSE initrd will also understand the better memorizable version scsi_noreportlun=1.
Devices known to be broken should be added to the blacklist with BLIST_NOREPORTLUN.
Oops; I didn't see that flag. It seems it was added at the same time LUN scanning became the default. It would be good to document the availability of default_dev_flags in /Documents/scsi.
It appears that the broken RAID systems are based on Maxtronic Arrays, such as the Arena Premium 8600. They just released a fixed firmware, so the source of the problem should be fixed. (It was also broken for Mac OSX.)
