This controller doesn't correctly detect devices (e.g. nCipher Crypter) with multiples LUNs. Only one LUN is detected. At another controller (e.g. Adaptec 79xx) two LUNs were detect. I compiled 2.6.8, 2.6.18 and 2.6.21.3 to test megaraid driver and all failed detecting two LUNs. I think that this is a firmware problem, but i'd like have some opinions. I read some docs (http://www.suse.de/~garloff/linux/scsi-scan/scsi-scanning.html, http://www.ictp.trieste.it/~radionet/nuc1996/ref/howto-html/scsi-howto-2.html) and this problem doesn't seem to be simple.
