Unable to access Webgui/SSH for one of the ESXi Host.

[anjan_mj]

Hi Gurus,

I have a 2 node ESXi Host Cluster managed by vcenter. I am running ESXi 6.5 U2. Both the ESXi is managed by vcenter and both the ESXi is showing as green in the vcenter console. Both the ESXi host has a similar configuration. When I try to access one of the ESXi hosts using WebGUI/SSH it is not accessible, however, the host is pingable. The Lockdown is disabled on both the host.

     I also tried to restart the SSH, ESXi SHell, DCUI Daemon from the Vcenter console on the ESXi host having the issue but still, the issue is not resolved.

Any suggestion or guidance by the Gurus is highly appreciated.

Thanks

AJ

Hi @anjan_mj

Check Cannot access Esxi 6.5 through Web or SSH

For what you are saying I guess that if you run a /etc/init.d/hostd status services should be running... Doble check please.

Maybe its a networking issue. Are you connected in the same L2 as the management interfaces of the esxi/vcenter or in a routed network?

Try this please:

Telnet the ESXi that is not working from your terminal.

• telnet ESXIIP 443

SSH into vCenter and:

• curl -v telnet://ESXIIP:443

Double check DG and Netmask configuration on the ESXi that is not working

Cheers

I have checked the question but in my case from the ISP router, and I have a single managed switch. Netgear "GS108PEv3 - 8-Port Gigabit Ethernet Smart Managed Plus ". I am not using any VLAN Tagging.

Suppose that doesnot fit my answer.

Thanks

Hi,

I am unable to login to the SHELL to check "/etc/init.d/hostd status". I am connected to a single layer 2 switch.

Checked the DG and Netmask it is configured properly.

The output of the command

root@vcsa [ ~ ]# curl -v telnet://10.0.0.110:443

* Rebuilt URL to: telnet://10.0.0.110:443/

*   Trying 10.0.0.110...

* TCP_NODELAY set

* Connected to 10.0.0.110 (10.0.0.110) port 443 (#0)

Thanks

This sounds silly, but can you do a reboot of the ESXi?

The telnet from your PC, is coonecting or not?

[anjan_mj]

Rebooted the ESXi host. Still, the issue persists. It seems some issues with Networking. Looking into it

Thanks

I am still not aware of what caused the issue. But now the issue is resolved. The only change i did was i removed the vss from each ESXi and migrated everything to vDS.

After the migration, everything is working fine.

Thanks
