where x is the letter of the failed controller (either A or B). 7. Enter save to save the modified settings. Setting the IP addresses for DS300 iSCSI ports To set the IP addresses for the iSCSI ports on the replacement controller for a DS300 storage subsystem, complete the following steps: 1. If a session is not already established, open a Telnet session to the replacement controller, using either the IP address assigned in "Configuring the management port" on page 51, or the default IP address 192.168.70.123. 2. Log in as administrator using either the default password (passw0rd) or the password that you defined previously. 3. To set the IP address for iSCSI port eth2, enter the following commands: interface manage eth2[x] ip IPaddress interface manage eth2[x] netmask netmask interface manage eth2[x] broadcast broadcast where [x] is the controller in a dual-controller storage subsystem (the [x] is not required for a single-controller storage subsystem), IPaddress is the IP address that you want to use for that port, and netmask is the management network subnet address. 4. To set the IP address for iSCSI port eth3, enter the following commands: interface manage eth3[x] ip IPaddress interface manage eth3[x] netmask netmask interface manage eth3[x] broadcast broadcast where [x] is the controller in a dual-controller storage subsystem (the [x] is not required for a single-controller storage subsystem), IPaddress is the IP address that you want to use for that port, and netmask is the management network subnet address. 5. Enter save to save the modified settings. See the IBM TotalStorage DS300 Problem Determination Guide or IBM TotalStorage DS400 Problem Determination Guide on the IBM Support Web site for a list of all the available commands. Importing foreign arrays For a single-controller storage subsystem, when the replacement controller is turned on, all the arrays that were previously defined on the controller will be defined as Foreign. To import the foreign arrays, you can use ServeRAID Manager or the command-line interface. Notes: 1. After the foreign arrays are imported, the data scrubbing rate is set to High (the default). 2. For a DS400 storage subsystem only: After the foreign arrays are imported, any previously defined port masking must be reconfigured. Using ServeRAID Manager to import foreign arrays To use ServeRAID Manager to import foreign arrays, complete the following steps: 1. Make sure that ServeRAID Manager has re-established a session with the replacement controller. If not, see "Configuring the management port" on page 51 and change the management port settings to match those of the failed controller. 2. Right-click on the Foreign array and select Import foreign array. 52 IBM TotalStorage DS300 and DS400: Hardware Maintenance Manual

Setting
the
IP
addresses
for
DS300
iSCSI
ports
To
set
the
IP
addresses
for
the
iSCSI
ports
on
the
replacement
controller
for
a
DS300
storage
subsystem,
complete
the
following
steps:
1.
If
a
session
is
not
already
established,
open
a
Telnet
session
to
the
replacement
controller,
using
either
the
IP
address
assigned
in
“Configuring
the
management
port”
on
page
51,
or
the
default
IP
address
192.168.70.123.

Importing
foreign
arrays
For
a
single-controller
storage
subsystem,
when
the
replacement
controller
is
turned
on,
all
the
arrays
that
were
previously
defined
on
the
controller
will
be
defined
as
Foreign.
To
import
the
foreign
arrays,
you
can
use
ServeRAID
Manager
or
the
command-line
interface.
Notes:
1.
After
the
foreign
arrays
are
imported,
the
data
scrubbing
rate
is
set
to
High
(the
default).
2.
For
a
DS400
storage
subsystem
only:
After
the
foreign
arrays
are
imported,
any
previously
defined
port
masking
must
be
reconfigured.
Using
ServeRAID
Manager
to
import
foreign
arrays
To
use
ServeRAID
Manager
to
import
foreign
arrays,
complete
the
following
steps:
1.
Make
sure
that
ServeRAID
Manager
has
re-established
a
session
with
the
replacement
controller.
If
not,
see
“Configuring
the
management
port”
on
page
51
and
change
the
management
port
settings
to
match
those
of
the
failed
controller.
2.
Right-click
on
the
Foreign
array
and
select
Import
