In the case of SCSI-IDE RAID arrays, many of which are of questionable quality, this typically means that the device is not providing a valid echo buffer size for performing domain validation. In this case, the driver defaults to running at the maximum speed supported by the device, but also prints out a diagnostic. I plan to remove the diagnostic for the echo buffer issue since there seem to be lots of broken devices out there. Your RAID array only supports U160, so it only runs at that speed. This has everything to do with the device, and nothing to do with the aic79xx controller/driver. As to the LUN issues, as already pointed out by others, it looks like the report luns support in this device is broken. Perhaps the vendor has a firmware update available. -- Justin - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
