CH(4) BSD Kernel Interfaces Manual CH(4)NAME
ch -- SCSI media changer driver
SYNOPSIS
ch* at scsibus? target ? lun ?
DESCRIPTION
The ch driver is essentially an ioctl(2) interface to a robot on a SCSI bus - a device that will change media (e.g. tapes, CD-ROMs, etc) in
and out of drives for that media. The chio(1) utility program uses this interface to manipulate such robots.
FILES
