48 Configuring the system
Changing network interface settings
You can configure addressing parameters for each controller's network port. You can set static IP values or
use DHCP.
In DHCP mode, network port IP address, subnet mask, and gateway values are obtained from a DHCP
server if one is available. If a DHCP server is unavailable, current addressing is unchanged. You must have
some means of determining what addresses have been assigned, such as the list of bindings on the DHCP
server.
Each controller has the following factory-default IP settings:
• DHCP: enabled
• Controller A IP address: 10.0.0.2
• Controller B IP address: 10.0.0.3
• IP subnet mask: 255.255.255.0
• Gateway IP address: 10.0.0.1
When DHCP is enabled, the following initial values are set and remain set until the system is able to
contact a DHCP server for new addresses:
• Controller A IP address: 10.0.0.2
• Controller B IP address: 10.0.0.3
• IP subnet mask: 255.255.255.0
• Gateway IP address: 0.0.0.0
CAUTION: Changing IP settings can cause management hosts to lose access to the storage system.
To use DHCP to obtain IP values for network ports
1. In the Configuration View panel, right-click the system and select Configuration > System Settings >
Network Interfaces.
2. Set the IP address source to DHCP.
3. Click Apply. If the controllers successfully obtain IP values from the DHCP server, the new IP values are
displayed.
4. Record the new addresses.
5. Sign out and try to access SMU using the new IP addresses.
To set static IP values for network ports
1. Determine the IP address, subnet mask, and gateway values to use for each controller.
2. In the Configuration View panel, right-click the system and select Configuration > System Settings >
Network Interfaces.
3. Set the IP address source to manual.
4. Set the options for each controller. You must set a unique IP address for each network port.
5. Record the IP values you assign.
6. Click Apply.
7. Sign out and try to access SMU using the new IP addresses.
