The DHCP server automatically assigns new IP addresses to the controller Ethernet
port.
Steps for assigning static TCP/IP addresses to the DS3950 controllers: To
complete this procedure, you must have the following components:
v
A host that is connected to a storage subsystem through a Fibre Channel I/O
path
v
A management station that is connected by an Ethernet cable to the storage
subsystem controllers
For a host that is connected to a storage subsystem through a Fibre Channel I/O path:
Complete the following steps to assign static TCP/IP addresses to the DS3950
storage subsystem controllers by way of the host that has Fibre Channel
connectivity to the DS3950 Fibre Channel host port.
Note: You cannot perform in-band management with a host that has iSCSI
connections to the DS3950 until it is configured. Use an out-of-band
management connection instead.
1. Install the DS Storage Manager client software in the host, and make sure that
the SMagent software is installed and running.
2. Start the DS Storage Manager client software. The Enterprise Management
window opens.
3.
Add the DS3950 subsystem to the Enterprise Management domain using the IP
address of the host that has Fibre Channel connectivity to the DS3950.
4. In the Enterprise Management window, click 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 drop-down menu. The Change
Network Configuration window opens.
6. In the Change Network Configuration window, click the Controller A and
Controller B tabs and type the new TCP/IP addresses in their applicable fields.
Click OK .
7. Close the Subsystem Management window, wait at least five minutes, then
delete the default DS3950 storage subsystem entry in the Enterprise
Management window.
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 DS Storage Manager, then restart.
9. Make Ethernet cabling to the controller management ports. Add a new storage
subsystem entry in the Enterprise Management window, using the new
assigned IP addresses.
For a management station that is connected by an Ethernet cable to the storage subsystem
controllers:
Complete the following steps to assign static TCP/IP addresses to the
DS3950 storage subsystem controllers, using default TCP/IP addresses that are
assigned to the DS3950 storage subsystem controllers during manufacturing:
1.
Make a direct management connection to the DS3950 storage subsystem, using
the default TCP/IP addresses:
v
Controller A: 192.168.128.101
v
Controller B: 192.168.128.102
v
Subnet Mask: 255.255.255.0
