Subscriber acquiring VIP (virtual IP) when Publisher is online

Hi,

Has anyone experienced a subscriber node acquiring the Virtual IP (VIP) even when the Publisher node is still online?

Event viewer is showing some events occuring after the daily automated backup and cleanup routine.

Some events show that subscriber acquires and releases the VIP on the same second!!! Other events show it takes a few minutes to realese the VIP, but all time the Publisher, which is primary VIP node, is online!!!

These nodes are VM appliances (version 6.5.6) and I´ve already checked the host vmware settings that coud affect server network traffic (vSwitch, promiscous mode, forged transmits, etc)

Any ideas?

Thanks!

Hi Heraldo,

 

I have seen this before. On the node that is not owning the VIP and you want to own the VIP. Make sure that the "Virtual IP service" is running under service control. It would show "Stop".

 

Let me know.

Hi Master-local,

Thanks for the reply.

On both servers, Publisher and Subscriber, the Virtual IP Service is "running".

What is strange is that the Subscriber, sometimes, acquires and releases the VIP at the same time!!!For example, if you see the event log image I attached you will observe this:

51 High AvailabilityINFOVirtual IP ReleasedNoneJun 07, 2016 04:28:56 BRT
52. High AvailabilityINFOVirtual IP AcquiredNoneJun 07, 2016 04:28:56 BRT

And on others occurences it takes a few seconds or a few minutes to release the VIP:

53. High AvailabilityINFOVirtual IP ReleasedNoneJun 07, 2016 04:26:57 BRT
54. High AvailabilityINFOVirtual IP AcquiredNoneJun 07, 2016 04:22:30 BRT
55. High AvailabilityINFOVirtual IP ReleasedNoneJun 07, 2016 04:22:18 BRT
56. High AvailabilityINFOVirtual IP AcquiredNoneJun 07, 2016 04:22:16 BRT

Is it possible that the Virtual IP Service is crashing and restarting on the Publisher node without logging anything in the Event Log/Viewer?

Thanks again!

Ive seen that happen on a VM if the vm network settings are not stable. My best guess is that its in the VM settings not CPPM
Thank You,

Hi Tarnold,

Thanks for the reply.

Any specific setting I should check?

I´ve already checked the host network settings (vSwitch->Standard, promiscous mode->disabled, forged transmits->enable) and I don´t know what could be causing this behavour!

Thanks again!
