Ever since reading about scsish(8) in the Reserch Tenth Edition manual,
I've wanted a similar command, and had/have hopes someone would find
more time than I have to re-implement it for *BSD.
Scsish(8) is an interface to V10's scsi(4), and it simply provides a
number of generic SCSI commands in a shell like environment, as well as
some peculiar to the special devices they had atached to the vax, such
as the SONY optical disk jukebox.
help - print help
id n - set the destination SCSI bus device number to 'n'
reset - attempt to reset the SCSI interface
start n - start drive 'n' spinning
stop n - stop drive 'n'
test n - test unit ready for drive 'n'
sense n - print the sense data for drive 'n'
ext sense n - print the extended sense data for drive 'n'
capacity n - get the capacity of drive 'n'
disk eject n - eject the medium from drive 'n'
inquiry [n] - print status about drive 'n', or all LUNs
read n b - read & print block 'b' from drive 'n'
With the SCSI-2 spec in hand I'm sure a good compliment of functions
could be implemented.
