84 IBM System Storage N series Hardware GuideAfter finishing setup, the system prompts you to reboot to make the new settings effective.Configuring dedicated interfaces with setupA dedicated network interface for the local controller whether the controller is in takeovermode. A network interface performs this role if it has a local IP address but not a partner IPaddress. You can assign this role by using the partner option of the ifconfig command.Example 7-6 shows how to configure a dedicated interface for the N series.Example 7-6 Configuring a dedicated interfacePlease enter the IP address for Network Interface e0b []: 9.11.218.160Please enter the netmask for Network Interface e0b [255.0.0.0]: 255.0.0.0Should interface e0b take over a partner IP address during failover? [n]:nConfiguring standby interfaces with setupIf the partner node fails, the system will activate the partner IP addresses that have beenpreviously assigned as takeover IP address. When the file server is not in takeover mode, thepartner IP address is not active. A network interface performs this role if it does not have alocal IP address but a partner IP address. You can assign this role by using the partneroption of the ifconfig command.Example 7-7 shows how to configure a standby network interface for the partner. You do notconfigure any IP addresses for the e0b interface.Example 7-7 Configuring standby network interfacePlease enter the IP address for Network Interface e0b []:Should interface e0b take over a partner IP address during failover? [n]: yPlease enter the IPv4 address or interface name to be taken over by e0b []: e0b7.3.6 Setting options and parametersSome options must be the same on both nodes in the HA pair configuration. Others can bedifferent, and still others are affected by failover events.In an HA pair configuration, options can be one of the following types: Options that must be the same on both nodes for the HA pair configuration to functioncorrectly. Options that might be overwritten on the node that is failing over. These options must bethe same on both nodes to avoid losing system state after a failover. Options that need to be the same on both nodes so that system behavior does not changeduring failover. Options that can be different on each node.Attention: If the partner is a VIF, you must use the VIF interface name.Tip: You can determine whether an option must be the same from the comments thataccompany the option value when you enter the option command. If there are nocomments, the option can be different on each node.
