This is a host adapter simulator that can simulate multiple hosts
each with multiple dummy SCSI devices (disks). It defaults to one
host adapter with one dummy SCSI disk. Each dummy disk uses kernel
RAM as storage (i.e. it is a ramdisk). To save space when multiple
dummy disks are simulated, they share the same kernel RAM for
their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
information. This driver is primarily of use to those testing the
SCSI and block subsystems. If unsure, say N.
This pseudo driver simulates one or more hosts (SCSI initiators),
each with one or more targets, each with one or more logical units.
Defaults to one of each, creating a small RAM disk device. Many
parameters found in the /sys/bus/pseudo/drivers/scsi_debug
directory can be tweaked at run time.
See <http://sg.danny.cz/sg/sdebug26.html> for more information.
Mainly used for testing and best as a module. If unsure, say N.
