Tiebreaker Configuration Field Definitions
Table F.4 describes Tiebreaker configuration fields.
Configuration
Description
SCI Latency Threshold
If Tiebreaker detects that SCI latency exceeds the threshold, it
sends an SNMP trap to the SNMP receiver. (Default value is
200ms).
MirrorLatencyThreshold
If Tiebreaker detects that the mirror latency of any mirrored disks
exceeds the threshold, it sends a SNMP trap for each mirrored
disk that exceeds the threshold. Check the mirror latency value by
navigating to: /usr/local/tiebreaker/[HA_Pair_name]/
Type #cat /usr/local/tiebreaker/[HA_Pair_name]/

The last number in the string is the latency value.
View mirror latency by performing an SNMP query in your MIB
browser.
SNMP Heartbeat Checking
Tiebreaker sends an SNMP heartbeat trap to monitor if the
Tiebreaker SNMP daemon is alive.
SNMP Heartbeat Checking
Interval (sec.)
The interval for SNMP heartbeat traps to be sent.
Tiebreaker Monitoring
Failover
Tiebreaker monitors the failover pair status (Health, Power
Control, SCI Latency, Mirror status and latency for stretched
clusters).
N
indicates Tiebreaker is not monitoring failover pair
status.
Y
indicates Tiebreaker is monitoring failover pair status.
Tiebreaker Policy
Policy to force the secondary server to take over when all
communications from the Tiebreaker 7700 Controller to the
primary 7700 Controller fails.
Yes
indicates the policy is active.
No
indicates the policy is not active and you must manually initiate
failover when an unresponsive server cannot be reset.
