IBM TotalStorage DS4300 Fibre Channel Storage Subsystem: Installation, User's, and Maintenance Guide
v Controller B: 192.168.128.102
v Subnet Mask: 255.255.255.0
Note: For a DS4000 subsystem that has two Ethernet ports per controller, such
as the DS4200, DS4700 and DS4800, use the Ethernet port that is
labeled #1.
2. Start the DS4000 Storage Manager client software. The Enterprise Management
window opens.
3. Add the DS4000 subsystem to the DS4000 Enterprise Management domain
using the default IP addresses.
4. In the Enterprise Management window, click on the name of the default storage
subsystem. The Subsystem Management window opens.
5. In the Subsystem Management window, right-click the controller icon and select
Change —> Network Configuration in the pull-down menu. The Change
Network Configuration window opens.
6. In the Change Network Configuration window, click on the Controller A and
Controller B tabs and type the new TCP/IP addresses in their appropriate fields.
Click OK.
7. Close the Subsystem Management window, wait at least five minutes, then
delete the default DS4000 storage subsystem entry in the Enterprise
Management window. The default DS4000 storage subsystem entry still
displays, but shows an "unresponsive" icon.
8. If applicable, change the IP address of the Ethernet port in the management
station to a value that is on the same TCP/IP subnet as the controller Ethernet
port IP addresses that you just assigned. Exit DS4000 Storage Manager, then
restart.
9. Add a new storage subsystem entry in the Enterprise Management window,
using the new assigned IP addresses.
Note: To manage storage subsystems through a firewall, configure the firewall to
open port 2463 to TCP data.
