HARD(3) HARD(3)
NAME
hard, wren - hard disk interface
SYNOPSIS
bind
#w[target[.lun]]/dev
/dev/hd0disk
/dev/hd0partition
...
DESCRIPTION
The hard disk interfaces (wren is a SCSI disk; hard is a
Safari's internal ST506 disk) serve a one-level directory
giving access to the hard disk partitions. The parameter to
attach defines the numerical SCSI target and logical unit
number to access. Both default to zero.
Each partition name is prefixed by hd and the numeric drive
identifier. The partition `disk' always exists and covers
the entire disk. The size of each partition as reported by
stat(2) is the number of bytes in the partition, so the size
of `disk' is the size of the entire disk.
The partition `partition' also always exists; it is the last
block on the disk. If it contains valid partition data,
those partitions will be visible as well. Every time the
device is bound, the partitions are updated to reflect any
changes in the partition file.
The format of the partition file is the string
plan9 partitions
on a line, followed by a partition specification on a line
consisting of a name and textual strings for the block start
and limit on the disk.
The program prep(8) writes the partition table for the disk;
its use is preferred to writing it by hand.
