b. Since the EQ/OS 10 Equalizer is in Backup Mode, it will not attempt to assume the cluster IP

addresses until a failover occurs.

5. Set the hb_interval global parameter (Heartbeat Interval in the GUI) to the Probe Interval parameter on the

EQ OS 8.6 system

times

the number of interfaces (VLANs) configured on the EQ OS 8.6 system. For

example if the EQ OS 8.6 Probe Interval value is "5" and there are 2 VLANs configured, set the hb_interval

global parameter to "10" on the EQ OS 10 system.

6. Reboot the EQ/OS 8.6 system to make the EQ/OS 10 system the primary unit: open the Equalizer >

Maintenance tab and click the reboot button.

7. Once the EQ/OS 10 system detects that the EQ/OS 8.6 system is not responding to failover probes, the

EQ/OS 10 peer configuration should indicate a change to Primary Mode. Use the command:

eqcli > peer eq_00:30:48:d3:ee:b6 stats

12200442: Peer eq_00:30:48:d3:ee:b6: Failover Group Status

12200443: Member of Failover Group : Yes

12200444: Preferred Primary : No

12200445: Peer OS : EQ OS/10

12200446: State : Probing

12200447: Substate : Start

12200448: Takeover : Primary Mode

12200449: Last Peer probed : eq_os8

12200450: Last Peer probed from : eq_os8

12200453: Number of interfaces : 2

12200456: Interface : Mgmt

12200457: State : Probing

12200458: Substate : Start

12200461: Number of strikes : 0

12200456: Interface : Mgmt

12200457: State : Probing

12200458: Substate : Start

12200461: Number of strikes : 0

The failover configuration is now complete, and the EQ/OS 10 system should have now assigned the cluster IP

addresses to itself. The EQ/OS 8.6 GUI should display initializing for failover mode on the Help > About

screen. Because of how failover in Version 8.6 works, the V8.6 unit will never transition to the backup failover

state -- this is normal when an V8.6 Equalizer is configured in failover with a V10 Equalizer. It will remain in the

initializing state until a failover occurs (while Equalizer is in initializing mode, it will not assume the cluster IP

addresses).

The Equalizer running EQ/OS 10 will serve client requests and the Equalizer running EQ/OS 8.6 will remain in

initializing mode. The two units will continuously exchange heartbeats with one another. Should the heartbeat

exchange on any interface fail three times and on all other interfaces once, then the Equalizer running EQ/OS 8.6

will attempt to assume primary mode and assign the cluster IP addresses in the configuration to itself. Once the

EQ/OS 10 system is available again, it will assume backup failover mode.

You can force the units to switch failover modes by rebooting the current primary Equalizer.
