To get it to swap disks, one references the other LUNs. The changer should automatically swap out one disk and insert the other. It looks like its doing what it should during the probe. I don't remember exactly what the SCSI spec. says for LUNs - I think reporting that the "Logical unit not supported" is valid for LUNs 6 and 7 - what else would a LUN type device report if it supports 6 out of 8 LUNs? Not sure what "device busy" from mount is trying to say... Chuck McCrobie To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
