Configuring
High
Availability
Understanding
ANM
High
Availability
ANM
Server
ANM
high
availability
consists
of
two
nodes,
which
both
run
the
ANM
software.
Each
node
must
have
at
least
two
network
interfaces
as
follows:
•
A
primary
interface,
normally
used
to
access
the
node.
•
A
heartbeat
i
nterface,
which
i
s
used
t
o
provide
additional
redundancy.
The
heartbeat
interfaces
of
the
two
nodes
must
be
connected
vi
a
a
c
rossover
Ethernet
connection.
•
The
two
Ethernet
interfaces
used
on
one
of
the
hosts
should
match
the
two
interfaces
used
on
the
other
host
,
with
regard
to
the
subnets
t
hey
participate
in.
For
example,
if
HA
Node
1
uses
eth0
for
the
primary
interface
and
eth1
for
the
heartbeat
interface,
then
HA
Node
2
should
also
use
eth0
for
the
primary
interface
and
eth1
for
the
heartbeat
interface.
Note
ANM
does
not
configure
the
primary
and
heartbeat
IP
addresses
of
the
nodes’
interfaces.
You
must
manually
configure
the
node’s
i
nterfaces.
When
you
installed
ANM,
you
provided
values
for
high
availability
parameters,
determined
the
node
IDs
of
the
two
nodes
designated
as
Node
1
and
Node
2
.
For
additional
information
about
the
installation
parameters,
see
the
Installation
Guide
for

CLI
Commands
for
ANM
High
Availability
Processes
You
use
two
commands
to
view
ANM
processes:
•
Use
the
/opt/CSCOanm/bin/anm-tool
command
to
start
and
stop
the
ANM
processes
and
to
view
the
status
of
the
ANM
processes.
•
Use
the
/opt/CSCOanm/bin/anm-ha
command
to
check
high
availability
configuration
or
to
force
a
node
to
become
standby
or
active.
Ta

lists
the
sub-
commands
and
their
descriptions.
