- 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.
