service, boot, standby, and serial adapters:
• Boot, standby, and serial adapters are tied to particular nodes, while service adapters are
not.
• Service adapters have associated hardware (MAC) addresses so that clients don’t have to
flush their ARP caches when it moves from one physical adapter to another.
• Serial adapters have a field that says “service”, but we don’t call them service adapters.
The SMIT path for configuring each adapter is the same
% smitty hacmp
Cluster Configuration
-> Cluster Topology
-> Configure Adapters
-> Add an Adapter
HACMP will complain if a boot or standby adapter is configured before their corresponding
service adapter. However, HACMP willnot allow a service adapter to beconfiguredbefore its
boot adapter is configured. So configure the boot adapters first and ignore the warnings.
