UDID
hexadecimal
representations
This
section
describes
UDID
representations
for
storage
unit
volumes.
The
UDID
for
each
volume
appears
as
-1,
signifying
that
the
UDID
is
undefined.
With
the
supported
storage
unit
LMC,
all
UDIDs
for
storage
unit
volumes
are
undefined.
The
underscore
in
Figure
12
highlights
the
hex
string
that
identifies
a
storage
unit
volume
that
is
attached
to
an
AlphaServer.
The
third
and
fourth
quartet
of
the
UDID
number
is
always
the
value
“4942-4d20”.
This
is
the
string
IBM
in
hex
and
represents
a
storage
unit
volume.
The
underscore
in
Figure
13
highlights
an
example
of
a
hex
string
that
identifies
the
decimal
volume
number
of
the
storage
unit
volume.
The
first
three
characters
of
the
next
to
last
quartet
of
numbers
is
the
hex
string
representation.
Figure
13
shows
that
the
storage
unit
volume
number
is
decimal
282.
Figure
14
shows
a
hex
representation
of
the
last
5
characters
of
the
storage
unit
volume
serial
number.
Preparing
to
boot
from
the
storage
unit
for
the
Tru64
UNIX
host
system
This
section
lists
the
steps
you
must
perform
to
prepare
to
boot
from
the
storage
unit.
Use
the
wwidmgr
command
to
set
up
each
device
that
you
use
for
booting
or
dumping.
After
you
set
up
a
device,
the
console
retains
the
information
that
is
needed
to
access
the
device
in
nonvolatile
memory.
Rerun
the
wwidmgr
command
if
the
system
configuration
changes
and
the
nonvolatile
information
is
no
longer
valid.
