IBM SG24-5131-00 manual Node Name

Adapter Identifier Enter the IP address in dotted decimal format or a device file name. IP address information is required for non-serial network adapters only if the node’s address cannot be obtained from the domain name server or the local /etc/hosts file (using the adapter IP label given). You must enter device filenames for serial network adapters. RS232 serial adapters must have the device filename /dev/ttyN. Target mode SCSI serial adapters must have the device file name /dev/tmscsiN. Target mode SSA adapters must have the device file name /dev/tmssaN.im or /dev/tmssaN.tm.

Adapter Hardware Address(optional) Enter a hardware address for the adapter. The hardware address must be unique within the physical network. Enter a value in this field only if: You are currently defining a service adapter, and the adapter has a boot address, and you want to use hardware address swapping. See the chapter on planning TCP/IP networks in the HACMP for AIX, Version 4.3:Planning Guide, SC23-4277 for more information on hardware address swapping. This facility is supported only for Ethernet, Token Ring, and FDDI adapters. It does not work with the SP Switch.

Node Name	Define a node name for all adapters except for those
	service adapters whose addresses may be shared by
	nodes participating in the resource chain for a rotating
	resource configuration. These adapters are rotating
	resources. The event scripts use the user-defined
	configuration to associate these service addresses with
	the proper node. In all other cases, addresses are
	associated with a particular node (service, boot, and
	standby)

Note

Although it is possible to have only one physical network adapter (no standby adapters), this constitutes a potential single point of failure condition and is not recommended for an HACMP configuration.
