.SH NAME
intro \- introduction to stand alone utilities: 
 boot, ls, cat, vdformat, vdverify, fastcopy, devcopy
.SH DESCRIPTION
This section contains information related to  the stand alone
utilities available in the /stand directory.  those 
utilities are used to format/verify new drives, copy from tape to
disk or from disk to disk, and install the root
file system during installation procedures.
.sp 2
DEVICE NAMES:
.PP
The stand alone utilities has a set of names for devices, which are different
from the full names for the devices.
The disk and tape names used by the stand alone utilities are:
.sp 1
.nf
.ta +8n +1n +14
	160 Mb FSD disks - fsd
	300 Mb SMD disks - smd
	340 Mb FSD disks - xfd
	515 Mb FSD disks - xsd
	Cypher tapes     - cyp
.fi
.DE
.PP
The stand-alone boot, used to bootstrap the full Power 6 Unix system,
uses device names:
.sp 1
	xxx(y,z)
.sp 1
where \fIxxx\fP is either fsd, smd, xfd, xsd, or cyp.
The value \fIy\fP
specifies the device to use.
The \fIz\fP
value is interpreted differently for tapes and disks:
for disks it is a disk \fIpartition\fP (in the range 0-7),
and for tapes it is a file number on the tape.
.PP
Each physical disk is divided into 8 logical disk partitions,
each of which may occupy any consecutive cylinder range on the
physical device.  The cylinders occupied
by the 8 partitions for each drive type
are specified in section 4 of the programmers manual
(\fIvddc\fP(4))
and in the disk description file /etc/disktab (c.f.
\fIdisktab\fP(5)).
.PP
All the utilities are loaded by the boot program which is started
in the mode which asks the user which file to load (See boot description
below). After each execution
the utility restarts from the beginning waiting for new arguments from
the user. To execute another utility
the boot has to be restarted.

boot	system boot program. Boots by default file /vmunix on
the default boot disk, unless cp monitor command (p23 2. or p23 3.) is
used during the cold boot process.
.br
p23 2. boots /vmunix to single user mode while p23 3. asks the user for
boot device and file to boot. This is also the command used to get the
boot activate the stand alone utilities.
See Power 6 Installation Manual and Console Processor Manual for detail.
.HP 14
ls	list a directory. Asks the user for directory name of the form
disk(unit,block)pathname.
.HP 14
cat	print a file on the console
.HP 14
vdformat	format drives on a vddc controller. Can format any drive
on any controller. Asks the user for controller number and drive name.
The name "other" can be used for a drive which is not one of the drive
types known to the driver (fsd, smd, xfd and xsd).  In this
case the program
asks the user for the drive parameters. (number of heads, sectors and
cylinders). The format takes 5 to 10 minutes to complete, depending on
the drive type. 
.br
An option to read/verify the drive is available after
the formatting. The program uses a full track read commands to read the
whole drive. Soft errors are reported while hard error terminates the
verify process. See the VDDC manual for status words reported by the
program.
.HP 14
vdverify	read/verify a drive on a vddc controller. Same as the
verify option of the vdformat program.
.HP 14
fastcopy	a fast copy program from tape to disk or from
disk to disk. It uses a large buffer (up to 63 Kbytes) for each read/
write operation.
.HP 14
devcopy	disk/tape to disk copy program. This program uses a 1Kbytes buffer
for I/O.
