Are you able to connect to the ESXi host directly using vSphere client?

Are you able to ssh to the ESXi?

On ssh session, please run the command cd /vmfs/volumes and press enter.

If the ssh session hangs after pressing enter, hostd will be in no responding state.

Open a new ssh session and try rescanning by running the command esxcfg-rescan vmhba# where #  is the number of the adapter.

Hi,

No, I am not able to connect it through neither ssh and vpshere client. I am only able to connect it through ILO.

Rescan the host from ilo. It looks to be storage issue.

Host is not able to access your storage. This might require a host reboot.

Yes, I am not able to access the storage also. But the issue is I am not able access anything. It is only accessible through ILO. When test management network, it fails on gateway. I have cross verify everything from network team as well and their end everything is fine.

Please suggest, what to check further.

I would recommend you to reinstall the host rather than investing much time on troubleshooting considering my business is impacted.It would take 15 to 20 minutes to reinstall the host.

What i am understanding is the server fully isolated from the network, i think you are using network base storage.

I am sure somthing problem with Network ( may be switch port , network port/cable) ..

If you doing below steps then you confirm there is no issue with ESX server.

Plan A:

Incase your managment network configured two NICs, please remove one & restart the network service and check whether you are able to access..

Plan B :

Remove the managment network completely and reconfigure it.

I have 4 Nics, when I switch my Management interface to other two nics, it works fine. But now the problem is, I had iScsi initiator configured on these nics.

Also when I am going to configure Vmkernel port for Vmotion, by default iScsi port binding is enabled.

Please let me know, how to resolve it and my host back to normal operation?
