Virtual Center 2.5 - All of my templates and VM (except for 3) shows disconnected

Hello Experts,

I just upgrade my MSSQL EXP server that comes in with VC 2.5 to MSSQL Enterprise server.    I was able to see all of my ESX boxes and VM's.  The only problem is that most of my VMs and Templates are in disconnected state.  This prohibits me for deploying a new VM from the template.  I am logged in as administrator.   Is there something wrong on the DB side?  any thoughts?

    confirm if the three machines that are showing as connected were online when you were upgrading the SQL DB. As there are instances where when any DB upgrades are done and if the ESX server is online connected to VC.

    Please go ahead and remove the ESX server from the VC and re-add them back.

    That should take care of the issue.

    It could be an issue with your service console.

    Try bhanukir7's suggestion but if that fails,
    console into the ESX server and run these commands

    service vmware-vpxa stop
    service mgmt-vmware stop

    wait for both to say [ OK ]

    service vmware-vpxa start
    service mgmt-vmware start

    Server should be reconnected.

    * If any of these services fail, you may try to kill the service directly, but this can cause the VMs to die. Take caution if the VMs are critical and cannot be powered off.

    ps -ef | grep "hostname"
    kill -9 <PID>
    service vmware-vpxa start
    service mgmt-vmware start

    This should not be done unless you really need to get the host back up at the cost of other vms. Could be as severe as a reboot command.
    Hope that helps.

    I did remove all of the ESX servers from the Cluster > Host tab.  Is it possible to add multiple ESX servers to the VC?

    the real purpose of using Virtual Center is to manage multiple ESX servers and if you have license for "vmotion" "DRS" "HA" you can create HA clusters DRS clusters and move VMs from one ESX server to another server without any issues.

    Virtual center is really a very wonderful management tool to manage ESX environments. But the real issue is the Licensing costs which are normally something that organizations with truckloads of money to spend.
