noblk
is
the number of FB-S12 blocks to be made available
for use.
If
the number specified exceeds the actual
number of blocks
on
the disk, then all the blocks
on
the disk are made available for use.
Options:
BLKSIZE
specifies the physical DASD block size
of
the CMS
minidisk. The block sizes
1024, 2048, and 4096
may alternately be specified as 1K, 2K,
and
4K,
respectively.
NOERASE
specifies that the permanently formatted FB-S12
blocks are not to be cleared to zeros.
If
not
specified, the FB-S12 blocks will be cleared.
LABEL
writes a label
on
the disk without formatting the
disk. The CMS disk label
is
written
on
block 1
of
an
FB-S12 device. A prompting message requests a
six-character disk label (fewer than six characters are
left-justified
and
blanks padded).
RECOMP
changes the number
of
FB-S12 blocks
on
the disk
that are available to the user. This number becomes
the actual number
of
minidisk FB-S12 blocks,
or
the
number specified
by
noblk, whichever
is
less.
If
noblk
is
not
specified, the maximum number of
blocks initially formatted
on
the disk is made
available to the user.
Usage Notes:
1.
When you
do
not
specify either the
RECOMP
or
LABEL option, the disk area
is
initialized by writing
records containing binary zeros
on
each block. Any
previous data
011
the disk
is
erased.
For
example:
format
101
a 1000
initializes 1000 blocks of the disk located at virtual
address
101 in CMS format. The command:
