shutdown
or
after
any
system
additions,
removals,
or
modifications
(including
firmware
updates,
logical
drive
creations,
storage
partitioning
definitions,
hardware
changes,
and
so
on),
save
the
storage
subsystem
profile
as
explained
in
the
DS4000
Storage
Manager
guide
for
your
operating
system.
Save
the
profile

created
for
the
DS4800.
Always
refer
to
the
readme
that
is
included
with
the
DS4800
Storage
Subsystem
firmware
package
(whether
the
firmware
is
accessed
by
the
Web
or
CD)
for
any
special
requirements
or
restrictions
that
apply
to
that
particular
firmware
version.
Note:
Make
sure
that
you
install
the
DS4000
Storage
Manager
event
monitoring
service
to
enable
continuous
monitoring
of
the
status
of
the
storage
subsystem.
For
more
information
about
the
importance
of
this
information,
see
Monitoring
status
through
software
Use
the
DS4000
Storage
Manager
client
to
monitor
the
status
of
the
storage
subsystem.
Run
the
software
constantly,
and
check
it
frequently.
Notes:
1.
You
can
only
monitor
storage
subsystems
that
are
within
the
management
domain
of
the
storage-management
software.
2.
If
you
have
not
installed
the
DS4000
Storage
Manager
Event
Monitor
service
as
part
of
the
storage-management
software
installation,
the
DS4000
Storage
Manager
Enterprise
Management
window
must
remain
open.
(If
you
close
the
window,
you
will
not
receive
any
alert
notifications
from
the
managed
storage
subsystems.)

ESM
firmware,
go

the
following
Web
site:

Note:
The
version
of
controller
firmware
determines
which
version
of

Storage
Manager
interface
is
displayed.
For
example,
the
interface
for
DS4000
Storage
Manager
version
9.19
subsystem
management
would
be
displayed
when
managing
a
DS4800
Storage
Subsystem
with
controller
version
06.12.xx.xx
installed,
even
if
the
installed
version
of
the
DS4000
Storage
Manager
client
code
is
actually
9.23.
The
DS4000
Storage
Manager
client
provides
the
best
way
to
