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?

Do you have raid configured? if you do reboot your server and see if you have any disk error.

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

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.

VMware, a software company founded in 1998, was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies. VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture. Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
