Configuring The Management Port - IBM TotalStorage DS300 Hardware Installation And User's Manual

11. Install the replacement controller:
12. Reconnect the Ethernet cables that were disconnected in step 3 on page 73.
13. For a Fibre Channel RAID controller only: Insert the SFP modules and
14. Turn on the storage subsystem if you turned it off in step 1 on page 73.

Configuring the management port

To configure the management port, complete the following steps:
1. Open a Telnet session:
2. At the command prompt, enter administrator.
3. At the password prompt, enter your administrator password.
Complete the following two steps for a dual-controller DS300 or DS400
storage subsystem only:
4. At the command prompt, enter controller peer enable.
5. To determine whether the peer controller is ready, enter controller
6. For all storage subsystems: When the peer controller is ready, change the IP
the procedure to replace the 512 MB system DIMM on the replacement
controller with the 1 GB system DIMM from the failed controller.
a. Make sure that the lever on each side of the controller is down as far as it
will go.
b. Push the controller into the bay until it meets resistance (approximately 6
mm [0.25 in.] from the end of the chassis).
c. While squeezing together the latch and lever, push both latches up as far
as they will go. The controller slides the rest of the way into the bay.
fiber-optic cables that you removed in step 4 on page 73.
v For a single-controller DS300 or DS400: Open a Telnet session to the
default IP address 192.168.70.123.
v For a dual-controller DS300 or DS400: Open a Telnet session to the IP
address of the active controller.
Note: The default administrator password is passw0rd (all lowercase letters
with a zero, not O, in passw0rd).
information. The peer controller is working correctly if the peer controller status
is Ready.
address and netmask address of the replacement controller to match your
previous management port settings:
v For a single-controller DS300 or DS400:
To change the IP address, enter interface manage eth0 ip
IP_address_of_failed_controller
To change the netmask address, enter interface manage eth0 netmask
network_mask_of_failed_controller
Note: For a single-controller storage subsystem, when you change the IP
address for the management port, you must establish a new Telnet session to
the new IP address.
v For a dual-controller DS300 or DS400:
To change the IP address, enter interface manage eth0[x] ip
IP_address_of_failed_controller
To change the netmask address, enter interface manage eth0[x] netmask
network_mask_of_failed_controller
where x is the letter of the failed controller (either A or B).
