Configure Tiebreaker
This section demonstrates how to configure Tiebreaker on the 7700 Controller on which the
Tiebreaker image was installed, and this example sets up Tiebreaker to manage a stretched cluster
failover pair.
To configure Tiebreaker, do the following:
1.
Execute
tiebreakersetup
and follow the prompts to configure the Tiebreaker utility.
You are prompted to select an action.
2.
Choose
a [A]dd
to add a new
failover
pair.
3.
You are prompted for the following information:
(This is the SNMP server IP address.)
(This is the amount of time in milliseconds that SCI latency is allowed. Once the SCI latency
reaches this value, an SNMP trap is sent.)
(Set this option to monitor the Tiebreaker SNMP daemon status.)
[root@tiebreaker ~]# tiebreakersetup
Select an action:
a) - [A]dd a failover pair
m) - [M]odify a failover pair
r) - [R]emove a failover pair
q) - [Q]uit
