can say Y here to force the SCSI driver to probe for multiple LUNs.
A SCSI device with multiple LUNs acts logically like multiple SCSI
devices. The vast majority of SCSI devices have only one LUN, and
so most people can say N here and should in fact do so, because it
is safer.

default y
help
If you want support for SCSI REPORT LUNS, say Y here.
The REPORT LUNS command is useful for devices (such as disk arrays)
with large numbers of LUNs where the LUN values are not contiguous
(sparse LUN). REPORT LUNS scanning is done only for SCSI-3 devices.
Most users can safely answer N here.
so most people can say N here. The max_luns boot/module parameter
allows to override this setting.

None currently. Also note this is very different to Brian's original driver

Also note this is very different to Brian's original driver
so don't expect him to support it.
Adaptec does support this driver. Contact either tech support or deanna bonds.

* # echo "scsi log timeout 0" > /proc/scsi/scsi

* The token 'hlcomplete' should be used but that triggers too
* much output from the sd device driver. To dump the current
