vSphere HA detected host in a different network partition than the master

[Genkitkl]

Hi everyone,

Recently we've did an upgrade of the VMWare from ESXi 6 to 6.7 for 3 hosts and left with one master on version 6.

A notification came up everyday with regards to the following.

"vSphere HA detected that host <host4> is in a different network partition than the master <host5>"

Also noticed that the speed of the nic changes to 1000MB instead of auto-negotiate for the upgraded hosts.

Any ideas on how to resolve the issue? Should I upgrade the master first and see if the issue is still happening?

It was all working fine when all the hosts are running version 6.

Upgrade all hosts 6.7 and see if the issue persists.

Upgraded all the host to VMWare 6.7 but the issue still persists. Ended up it was some kind of network issue resolved by the network team. :smileysilly:
