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.

This option will force the SCSI driver to probe for multiple LUN's. Without this option only one LUN may be detected, and since that's the common case (devices only having one LUN) people often forget about this option :) -- Jesper Juhl <[EMAIL PROTECTED]> Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
