frequently HA connection down

u4353 — Fri, 03 Jun 2011 20:25:31 GMT

Hi,

we have 2 PA-500 configured in active-passive mode.

Since two week ago we frequntly receive na alarm about the Ha connections that goes down and then goes up.

We have checked and changed the crossover cable used for the Ha interface; we have increased the parameteres for the HA checks...but the PA continue to register event like :

SYSTEM ALERT : high : HA Group 1: Link group 'HA' link 'ethernet1/8' is down
SYSTEM ALERT : critical : Chassis Master Alarm: HA-event
SYSTEM ALERT : critical : HA Group 1: Link group 'HA' failure; one or more links are down

Anyone have some tips for us?

Thanks!

We've had a similar problem. Try using different ports as HA and see if that helps.

We changed th ha link to another port, unortunately that didn't resolve the problem.

The PA System logs continue to show these messages:

SYSTEM ALERT : critical : HA Group 1: All HA1 connections down
SYSTEM ALERT : critical : HA Group 1: Staying in Active state after split-brain recovery (split-brain duration: 10s)
SYSTEM ALERT : critical : HA Group 1: Going to Passive state due to split-brain recovery (split-brain duration: 10s)

Some others tips?

Thanks!

Hello,

This could be a result of the HA settings in combination with the release and resources being used at the time of the split brain event.

You should open a support case to have a closer look.

I have exprenced the same problem but solved and changed HA particular value that heartbeat-interval from 1000msec to 3000msec that Tech Support suggested.

I don't find any problem after timer change until now.

Thanks.
