HACMP Installation and Cluster Definition 
103
Network Name
Enter an ASCII text string that identifies the network. 
The network name can include alphabetic and numeric 
characters and underscores. Use no more than 31 
characters. The network name is arbitrary, but must be 
used consistently for adapters on the same physical 
network.
If several adapters share the same physical network, 
make sure you use the same network name for each of 
these adapters.
Network Attribute
Indicate whether the network is publicprivate, or 
serial. Press Tab to toggle the values. In the context of 
HACMP, serial networks means “non-TCP/IP”; public 
and private networks are TCP/IP networks. Ethernet, 
Token-Ring, FDDI, and SLIP are public networks. 
SOCC, ATM, and an SP Switch are private networks. 
RS232 lines, target mode SSA loops, and target mode 
SCSI-2 buses are serial networks.
Adapter Function
Indicate whether the adapter's function is 
service, 
standby, or boot. Press Tab to toggle the values. A node 
has a single service adapter for each public or private 
network. A serial network has only a single service 
adapter. 
A node can have none, one, or more standby adapters 
for each public network. Serial and private networks do 
not have standby adapters, with the exception of ATM 
networks. ATM networks must be defined as private, 
and therefore standby adapters are supported. 
In an HACMP environment on the RS/6000 SP, the 
ethernet adapters can be configured as service 
adapters but 
should not be configured for IP address 
takeover. Regarding the SP Switch, network, boot, and 
service addresses used for IP address takeover are 
ifconfig alias addresses used on the css0 network. See 
the appendix entitled HACMP for the RS/6000 SP in the 
HACMP Installation Guide Version 4.3 for more 
information on adapter functions in an SP Switch 
environment.
In an ATM network, the adapter function should be listed 
as svc_s to indicate that the interface is used by 
HACMP servers. Keep in mind that the netmask for all 
adapters in an HACMP network must be the same.
