cannot connect to ESXi host

[Tcpuniverse]

Hi;

First of all I'm completely newbie in Vmware. I was working on my project and suddenly the power went down and came back again. after that, I cannot connect to my ESXi 6.0 host. I can ping and even can connect remotely by SSH. But neither Vsphere Client nor HTTP/HTTPS work. I searched the net and found that "hostd" and "vpxa" are not running. I started the processes but after some seconds they stopped automatically. Here are commands:

[root@timaz-esxi:~] /etc/init.d/hostd status

hostd is not running.

[root@timaz-esxi:~] /etc/init.d/hostd start

Ramdisk 'hostd' with estimated size of 303MB already exists

hostd started.

[root@timaz-esxi:~] /etc/init.d/hostd status

hostd is running.

[root@timaz-esxi:~] /etc/init.d/hostd status

hostd is not running.

[root@timaz-esxi:~] /etc/init.d/vpxa status

vpxa is not running

[root@timaz-esxi:~] /etc/init.d/vpxa start

[root@timaz-esxi:~] /etc/init.d/vpxa status

vpxa is running

.

.

.

after a minute:

.

[root@timaz-esxi:~] /etc/init.d/vpxa status

vpxa is not running

[root@timaz-esxi:~] /etc/init.d/hostd status

hostd is not running.

I checked the log files and here they are:

And this is what I got while trying to connect to the ESXi host with Vsphere Client:

I have many VMs on that ESXi host. How can I fix the issue or get my VMs from that ESXi host? tnx.

[IT_pilot]

Do you use vSAN? Could it be that there ended the place? A lack of space can affect the inaccessibility of ESXi.

[Tcpuniverse]

no I don't use vSAN. ESXi host has a local disk.

[Tcpuniverse]

interestingly I upgraded it from 6.0 to 6.5 but the same problem is still there; That I can connect to the host via SSH but not via HTTP/HTTPS/Vsphere Client.

[vijayrana968]

You won't able to connect ESXI 6.5 with traditional vSphere c# client. In browser you have to connect with https://ipaddressofEsxiHost/ui

[Tcpuniverse]

It's impossible to connect to my ESXi host via HTTP/HTTPS; As I said, I can only connect to it via SSH.

[Finikiez]

Can you attach hostd.log file here so I could check?

[golddiggie]

Can you get into the BIOS/UEFI of the host and check to make sure all the hardware is still working properly?? Having power pulled hard (and in the wrong way) can cause actual hardware damage. Depending on the make/model of the host server, it should include some kind of memory test item (usually runs on boot), if you had disabled that, turn it back on and let it do a full check. Then go through the drive controller, and the rest of the hardware (including checking to make sure the hard drives are kosher).

IF everything comes back clean, you might have to do a wipe and reinstall of ESXi on the host.

Assuming this is a standalone host without a vCenter Server connected to it... Right?

[Tcpuniverse]

None of actions helped me. I finally decided to install a clean version of ESXi while preserving the existing VMFS and it worked! After setup, I re-register the existing VM to the new ESXi host.
