a. Type the IP address for the primary HA Server.
b. Type the IP address for the secondary HA Server.
c. Type a shared password that will be used for authentication of the heartbeat links
between the primary and secondary servers.
NOTE: Make a note of the shared password that you set for the
heartbeat authentication. You need to configure the same password
when installing NSM on the secondary server.
d. Type the number of heartbeat links between the primary and secondary machines.
e. Type the IP address for this machine's primary heartbeat link.
f. Type the IP address for the peer's primary heartbeat link.
g. Type the port number used for heartbeat communication.
h. Enter a time interval in seconds between heartbeat messages.
NOTE: For larger deployments (that is, more than 1000 managed
devices), increase the default heartbeat interval to a value proportional
to the number of devices that you are managing greater than 1000
devices. For example, the default heartbeat interval is 15 seconds. This
interval is appropriate for deployments of fewer than 1000 managed
devices. If you plan to use NSM to manage more than 1000 devices,
we recommend that you set the heartbeat interval to 30 seconds. As
a general rule, we recommend that you double the timeout interval for
every 1000 devices that you are managing.
i. Enter the number of missing heartbeat messages before automatic switchover
occurs.
j. Enter an IP Address outside the cluster to be used to monitor this server's network
connection.
k. Type a number specifying how many seconds you want the management system
to wait while performing backups until the process times out.
l. Designate a directory location for locally storing the NSM database with HA backup.
Press Enter to accept the default location
m. Type the full path where the rsync utility is located.
n. Enter the full path to the ssh executable.
