ESXi Hosts disconnected from vCenter Linux Appliance
Posted on 2014-10-22
Running the VMware Linux appliance on 1 of 3 ESXi 5.1 hosts. All 3 ESXi host are shown as disconnected and I cannot reconnect them.
Right-clicking the host and choosing 'Connect' first gives me a "Authenticity of the host's SSL certificate is not verified" warning. After closing that dialog box, I get to the "Specify Connection Settings" where I enter the ESXi hostname (pre-populated) and the username/password. I receive a popup stating "Unable to verify the authenticity of the specified host. I choose "Yes" to continue.I then receive the following error:
"Cannot contact the specified host. The host may not be available on the network, a network configuration problem may exist or the management services on this host many not be responding."
I get the same error trying to connect to each of the 3 ESXi servers. Also noteworthy is that if I SSH into the vCenter Linux appliance and run a ping test, I get dropped pings. "IFCONFIG" shows a lot of dropped packets. If I SSH directly into the ESXi host where the vCenter Linux appliance is running and do a ping test, there is no packet loss.
From the CLI of the vCenter Linux Appliance I can successfully ping the ESXi hosts via the FQDN, but there is packet loss.
Any ideas on how to get the ESXi hosts reconnected? The vCenter Linux appliance gets it's IP address from DHCP so that would have to be taken into account if a reboot of the VM is suggested. I cannot do anything that would interrupt the running VMs on any of the hosts.
Thanks in advance for your ideas/assistance!
