Attached
to
a
Non-RAID
and
PCI-X
SCSI
Adapter
Attention:
This
service
aid
only
applies
to

For

the
Diagnostic
RAID
Array
Manager
task

to
be
run
on
the

hdisks:
v
Hard
File
Format
For
hdisks,
this
selection
writes
all
of
the
disk.
The
pattern
written
on
the
disk
is
device-dependent;
for
example,
some
drives
may
write
all
0s,
while
some
may
write
the
hexadecimal
number
5F.
No
bad-block
reassignment
occurs.
v
Hard
File
Format
and
Certify
Performs
the
same
function
as
Hard
File
Format.
After
the
format
is
completed,
Certify
is
run.
Certify
then
reassigns
all
bad

encountered.
v

Erase
Disk
This
option
can
be
used
to
overwrite
(remove)
all
data
currently
stored
in
user-accessible
blocks
of
the
disk.
The
Erase
Disk
option
writes
one
or
more
patterns
to
the
disk.
An
additional
option
allows
data
in
a
selectable
block
to
be
read
and
displayed
on
the
system
console.
To
use
the
Erase
Disk
option,
specify
the
number
(0-3)
of
patterns
to
be
written.
The
patterns
are
written
serially;
that
is,
the
first
pattern
is
written
to
all
blocks.
Then
the
next
pattern
is
written
to
all
blocks,
overlaying
the
previous
pattern.
A
random
pattern
is
written
by
selecting
Write
