Problems Adding ESXi Host to Windows vCenter Server

  • 1.  Problems Adding ESXi Host to Windows vCenter Server

    Hi all,

    I have a little lab set up in which I'm trying to add an ESXi host to my Windows vCenter server (VM) but getting an error.  I've attached a screenshot of the error message I'm getting.

    The strange thing is that the error seems to only happen on my Windows vCenter server and not my Linux vCenter appliance.

    The ESXi host I'm trying to add is at the other end of a VPN tunnel.  There are two hosts at that end of the tunnel, one of which I'm able to bring into vCenter with no issues.

    I thought it might be something to do with the E1000 network adapter so I switched the machine over to the VMXNET3 adapter.  The same issue happens with this adapter.

    I can't even use the VI client to connect directly to the ESXi host.  However, a person who's located at the other end of the VPN tunnel on the local network there says they can connect to the ESXi host with the VI client, no problem.  That leads me to believe it's something to do with the networking settings.

    Has anyone else experienced an issue like this?  I've searched the KB and forums but don't seem to be able to find any issues quite the same as this.

    Thanks,

    The error is specifically stating naming issue.  Can you verify that the resolution is working correctly?

    DNS resolution is working for the host I'm trying to add.

    Are both hosts returning similar return time for network connectivity?  Both hosts configured identically?

    Actually, the latency on the host that was added successfully is a bit higher than the latency for the host I'm trying to add.

    Both hosts are on the same subnet at the other end.  The hardware is a little different for each ESXi host, but still running supported network chipsets.

    Can you check the logs on your esxi host under /var/log while you initiate the addition form vCenter?

    Is there a particular log file I should be checking?

    Also, the server is a diskless server booting off a USB stick.  I'm not sure if it's logging everything that I need it to be logging.

    Thanks,

    Aha!  Found this in the hostd log file:

    2012-04-06T16:02:09.156Z [4250FB90 warning 'Proxysvc Req01514'] Writing response from localhost:8089 to client failed with error N7Vmacore15SystemExceptionE(Broken pipe).

    I can see the local address is my ESXi host and the peer address is the vCenter server I'm trying to add the host to.

    Any thoughts?

    Hmm, I guess we must assume that the local ESXi cert is bad if the other host is connected fine.

    On your ESXi host, cd to /etc/vmware/ssl, move those files to another location, and restart your management agents with '/sbin/services.sh restart'

    Doing that has caused it so that vCenter can't connect to the host.

    The exact error is "Cannot contact the specified host.  (<IP/FQDN>).  The host may not be available on the network, a network configuration problem may exist, or the management services on this host may not be responding."

    Check back in the same location to see if those keys were re-generated.  Until the hostd daemon is restarted, vCenter will not be able to connect.  Check the hostd.log to make sure it has BEGIN in the log to start servicing request.
