MSE 7.4: HA heartbeat

Hello!

we have two 3355 7.4 MSE appliance in different locations.

They are in the same VLAN (L2 domain).

MSE1 is primary, MSE2 secondary.

  • MSE1  10.1.1.2
  • Virtual  10.1.1.1
  • MSE2   10.1.1.3

MSE1 and MSE2 can ping each other, but can't join in HA pair. MSE can also ping Virtual IP address. But, heartbeats are down.

after trying to add MSE2 to MSE1 from Prime GUI

(Services > Mobility Services Engines> System > Services High Availability > Current High Availability Status) it is ssen:

"Initial setup of high availability configuration has failed. Lost heartbeats with the Secondary. Will retry."

information from MSE2

[root@MSE2 ~]# /etc/init.d/msed status

STATUS:

Health Monitor is running

MSE services are down. This is a secondary server. Services will not be started

unless -

                * This secondary is paired with a primary and the primary is up

and synchronized with this secondary

                        OR

                * Associated primary server is down and this server is failing o

ver for it

Hi Jaaazman777 .

I have same problem.

Can you say, did you solve problem?

Can you explain how ?

Thanks

For Primary and secondary unit , enable this feature

configureCiscoJ.sh enable

For Primary and secondary unit , break HA

breakHAsetup.sh

 

from the prime infrastructure 

Delete Primary MSE and delete secondary HA configuration

then add primary using VIP , after that add the secondary.
