46 Configuring the system
Changing host port settings
In order for hosts attached to the storage system's host ports to properly access the system, you must
configure the system's host-interface options.
To change FC host port settings
1. In the Configuration View panel, right-click the system and select Configuration > System Settings >
Host Interfaces.
2. Set the speed to the proper value to communicate with the host. Speed can be set to auto, which
auto-negotiates the proper link speed with the host, or to 2Gb (Gbit per second) or 4Gb. A speed
mismatch with a host prevents that host from accessing the storage system.
3. Set the connection mode to loop or point-to-point. Loop protocol can be used in a physical loop or in a
direct physical connection between two devices. Point-to-point protocol can only be used on a direct
physical connection between exactly two devices.
4. Click Apply.
Changing network port settings
You can configure addressing parameters for each controller's Ethernet management port, known as the
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.
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 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 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.
