Hi to all

Long post warning

Running "rescan-scsi-bus.sh -w -c"

gives me

0 new device(s) found.
0 device(s) removed.

and looking at /proc/scsi/scsi gives me

cat /proc/scsi/scsi

telling me that it does not detect the drive. Cable perhaps (will
replace that later today)

Both the controllers (old and new) is adaptec controlers

running "lshw > ~/hw" I get (only relevant sections)

Running "lsmod" | egrep -e "aic7xxx|aic79xx"

aic7xxx               127096  0
aic79xx               145912  0
scsi_transport_spi     23036  2 aic7xxx,aic79xx

shows me that the modules has been loaded for the adapters.

If I read the correctly it should pick it up under lshw, even without
the drivers/modules being loaded.
