Pinned topic Active member in AO self-balance cluster not balancing the load

‏2012-04-24T16:01:47Z |
Hi

I am having an issue that I can't find an answer for.

We have for xi50 DataPower in a AO cluster. The Active DataPower is not balancing load to the other DataPowers in the clusters.

I have checked everything I can think of.

When I look in the self-balanced-status on the active appliance I see that the other DataPowers are show with a weight or 0, so they will not be balanced to.

I have reloaded and rebooted one of the passive DataPowers with no change.

I then started taking packet captures. I can see the HSRP traffic between the DataPowers and I can see the broadcast traffic when I quiesce and unquiesce an application domain on on of the standby DataPowers, but nothing changes.

Any suggestion what can cause this issue.

This is happening in Production, so I will reload the active DataPower tonight to see if that fixes the problem.

Not happy with this as I would like to understand why, but production is production.

    For production issues you should raise a PMR to get help.

    There has been APARs related to the weight of a member being stuck at zero which have been fixed in recent fixpacks. What is your firmware version? I agree with Hermann that a PMR will verify your situation is the same as on fixed previously, but my bet is an upgrade to the latest fixpack will work for you.
