of
an
IBM
3330
Disk
Storage,
an
IBM
3333
Disk
Storage, or
an
IBM
3340 Direct Access Storage Facility onto another
disk device
of
the same type
in
a short time. The pack
to
be copied may
contain any combination of
DOSIVS data sets and system components.
The contents of this disk may be copied

Initialize
Data
Cell
Purpose:
To
prepare from one
to
five new or expired cells for use on
an
IBM
2321
Data
Cell
Drive.
Initialize Disk
Purpose:
To prepare one
complete disk pack for
use
on
an
IBM
2311
Disk
Storage
Drive, an
IBM
2314 Direct Access Storage Facility, an
IBM

The program can also be used:
To change the
volume label(s) and the
VTOC
(volume table
of
contents)
address
of
a previously initialized disk pack (other than an emulator pack).
If you specify
IS
in
the input option parameter of the utility modifier
statement, surface
analysis,
HA
(home address). and
RO
(track descriptor
record) generation are bypassed. This option assumes that a
valid
VTOC
is
present. A work pack used for
OS
can therefore
be
converted into a work·
pack suitable
to
be used for DOSIVS.
Initialize Tape
Purposes:
Page

To write one
to
eight I
BM
standard tape volume labels
