Esxi 6.5 not connected

Esxi 6.5 is in not in connected state.
I restarted the management service.
I checked VMkernel log and noticed error related to local disk and vmbha0.
Web client does not launch on that esxi host and 503 error.
I have to plan a maintenance time to reboot this esxi.
I wonder whether anyone had this problem. If so what is the fix for this?

Did you try rebooting the whole server?
Do you have raid configured? if you do reboot your server and see if you have any disk error.

Unfortunately, I can not reboot the esxi host since it hosts several VMs which require shutdown.

What the logs says? could you please have an screenshot or copy and paste?

Web client does not launch on that esxi host and 503 error.

I know you did reboot the services, but you might try doing it via ssh and debug the problem from the terminal.

Did we tried right click and connect the host what is the error you got ?
Mr TorturSystem EngineerCommented:

You could try to get more information if iLO / iDRAC / IMM is present and accessible according to your hardware.
So the VM on this host are online... So there are components working (vm network, storage, etc...) and other not (vcenter agent? management network? yes if you can ssh it..).
Have ther been some changes recently that could impact this host?
Where its VM are stored, locally, or onto a SAN array?
These are some suggestions to debug and find the root cause, hope it could help.

Strange, it fixed on its own after few hours. It stumped me, I have not done anything to fix it other than restarting the management  agent. I  was able ssh into the host. Df-h or la-l took very long time to give the result.
I noticed the error related to vmhba0 and also these are related to local disk and controler driver. They all disappeared after the reboot.
