You will define in the conf file:
backing-store /dev/sdb <bstype> 
bstype can be aio, mmap, null, rdwr or ssc.

and the equivalent tgtadm command will be something like:
tgtadm -- tgtadm --lld $driver --op new --mode logicalunit --tid $next_tid --lun $lun -b $backing_store -E $bstype

btw,
what is the "device-type" config option?



Thanks,
Doron
