I do see in the logs where it says that the failover completed successfully yet the services did not failover and that could be due to the networking not failing over. I just want to make sure this is not due to the upgrade.

When you say the takeover didn't work, do you mean that the A controller didn't take over at all (you didn't have to do a giveback), or was it only the network that didn't fail over properly? What other messages were seen when A tried to take over B? -Brad

I installed the upgrade version on both the controller than performed the cf takeover from controller B to controller A and it went fine. I then waited about 10 minutes and did the cf giveback and that also went fine. after waiting another 10 minutes I tried the cf takeover from controller A to controller B and I got the version mismatch error. I then issued cf takeover –n and at the time controller A did not took over controller B but just rebooted controller B. This caused a downtime with our vmware farm as servers lost connection to the data store on controller B. This is with NFS protocol. I only see this error in the logs

This explains why the takeover did not work but does not explain why this happened in the first place. I have worked with Netapp and validated that the rc file is correct and we have done failover and failback in the past without any issue. I also did the failover and failback after this to rule out configuration issue but could not recreate it. I need to upgrade 3 more HA pairs and I want to know if anyone has seen this issue before and does this have anything to do with the upgrade.
Thank you
