you need to tell your kernel to scan beyond the first 128 LUNs (this, assuming that all your devices come from the same SCSI controller. if not - you'll need to be more specific about your problem). by the way, i saw a bug in some version of sg3-utils, which made it unable to see devices beyond the first 128 (it did not check the 8 higher SCSI device majors). if these two things are not the problem - you'll need to tell us what kind of setup you have there (which SCSI devices, how they are configured, what linux kernel, which SCSI HBA, etc.). -- guy "For world domination - press 1, or dial 0, and please hold, for the creator." -- nob o. dy ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
