# SCSI drives
#
# NOTE: The Builddisk application and /usr/etc/disk now are able to
# automatically determine SCSI disk geometry and capacity for SCSI disks
# that support the MODE SENSE command -- no disktab entry is required.
#
# Currently, these programs will build single and dual partition disks, so
# disks requiring 3 or more partitions must still be specified in /etc/disktab.
#
# If an entry is specified in /etc/disktab it will be used in
# preference to the default parameters chosen by /usr/etc/builddisk and
# /usr/etc/disk.
