The issue is in the frequency of the alert.

Hi

thanks for your reply, but IF we disable this Alarm then the host will not disconnect & there will not be problem  for the othere host which it running in production now

Thanks

You can disable the alarm on the host level. Just doing it by selecting the host and browsing to Alarms.

Hello,

Then the issue is in the connectivity to the server, did you try to reconnect? right click on the host and choose connect.

Do you have firewall between vcenter and DR ESXi can you check if the required firewall port is opened between ESXi and VC/DNS servers, to avoid frequent disconnect of esxi to vc.

port to be opened between vc and esxi

902, 5989, 80,443,623, 8000, 8001, 6500, 514,8080

port to be opened between esxi and dns server

53, 88, 389
