Invalid
logical
volume
size.
See
the
help
text
for
this
message
for
valid
sizes.
Explanation
The
specified
volume
size
is
not
supported
on
all
platforms.
Supported
logical
volume
sizes
are
microcode
level
dependent.
For
DS
microcode
levels
5.0.3
and
above:
v
Supported
Enterprise
Storage
System
(ESS)
logical
volume
sizes
range
from
0.1
to
982.2
decimal
gigabytes
(1GB
=
10^9
bytes).
You
can
calculate
the
exact
number
of
512
byte
blocks
as
INT((INT(GBx10^9/512)+63)/64)x64.
The
size
of
the
volume
that
is
created
on
the
ESS
is
identical
to
the
size
of
the
volume
that
is
created
on
the
DS.
v
Supported
DS
logical
volume
sizes
range
from
1
to
2048
binary
gigabytes
(1GB
=
2^30
bytes).
This
allocation
uses
the
storage
capacity
of
DS
systems
most
efficiently.
v
Supported
block
logical
volume
sizes
range
from
1
to
4
binary
gigablocks
(1
gigablock
=
2^30
512-byte
blocks).
If
a
specified
size
matches
a
supported
DS
or
ESS
logical
volume
size,
the
volume
is
identified
as
a
DS
or
ESS
logical
volume,
even
though
it
is
created
by
specifying
the
blocks
volume
type.
v
Supported
iSeries
logical
volume
sizes
are
expressed
in
decimal
gigabytes
(1GB
=
10^9
bytes):

For
DS
microcode
levels
5.0.1
and
5.0.2,
block
logical
volume
sizes
must
be
a
multiple
