 How to fix if ESXi host is showing Not responding in vCenter

Below steps you need to check

Scenario 1 -> if the host is reachable and there is no lockdown mode enabled at host level.

1. Ping the host

C:\Users\administrator>ping 192.168.1.51

Pinging 192.168.1.51 with 32 bytes of data:

Reply from 192.168.1.51: bytes=32 time<1ms TTL=64

2. Login to host using web client -> If everything is fine start SSH service.

Login to ESXi host using putty console

Check VPXA service using below command

etc/init.d/vpxa status

Start the service using below command

etc/init.d/vpxa start

Now go to vCenter and check the status, it will take 2-3 minutes to sync.

3. Scenario -> In case lockdown mode is enabled on ESXI host level 

As the lockdown mode is enabled on ESXi host level so you can’t connect using Webclient directly.

Login to iLO console -> Take remote console

Press F2 to login to host using DCUI with root credential

Go to troubleshooting options

Restart management agent

Press F (11) to restart management agent

Now management agent is restarting

Now go to vCenter and wait for 3-4 minutes to sync
