Any updates on this ? i’m having a similar issue with the same version U1a (upgraded to U1b about a week ago). Can you check on the performance data if there’s an increase usage on the network resources when the disconnection happens?

TIA

Hello mate,

Did you get to know why this issue arised all of a sudden? Did VMware support guys clarify as to why you had this firewall issue? Were there any changes done which triggered this issue?

Regards,
Kanth

Hi, we checked the void and vmkernel log files and also the storage systems logs to verify access patterns. Yes there were VMs running on the ESXi host that could successfully be migrated to another ESXi host was back to vCenter Server.
That’s the firewall i’m talking about. When disabled you’ll see no rules in the vSphere Web Client or vSphere client for that ESXI host.

Hi Magnus,

Thanks for the article; just wanted to ask couple of things

What logs did you see that made you realize that it’s the firewall which is causing the issue?

Were there any VM’s running on this host? If yes once the local firewall was disabled on the host and when it joined the VC; then were you able to vmotion the vms to a different host?

Last, when you say ESXi Host local firewall are you referring the firewall of the ESXi that we can under configuration tab >> security >> under services or is it something else.

Thanks
Vaibhav
