Many of you may trying to upgrade the Virtual Center Server 2.5 U3 which recently release from VMware. As usual, I always like to be the earlier bird to test out everything and be excited to implement to my environment. Here is what I discover during the after the upgrade.
During the upgrade, there is the SQL script at the backend which trying to upgrade your DB table for your virtual center database and update manager. It does show some error during the upgrade and the screen will dissapear. Once it complete, you will find that your virtual center are still functioning as usual. 2 days later, you will start realize the Virtual center services is not able to be started anymore. Now is the big problem come. If you have backup your DB before the upgrade, you should be good. Or else, you will lose whatever data previously you have. Always backup the DB before any upgrade.

Few days ago, one of my virtual center machine was crashed and my Microsoft SQL database was corrupted without backup(damm!).
Basically setting up a brand new Windows 2003 machine is pretty simple but setup a new Virtual Machine took me 2 days. The most important is my VM template is go missing. The quick solution is search for VM template and register (add to inventory) again.
SSH into my ESX server using putty and search for VM template file with extension “.vmtx”.
[root@malaysiavmesx01 vmfs]# find /vmfs -name *.vmtx
/vmfs/volumes/465eeddb-89b75750-a52d-011aa0289d15/W2K3STD/W2K3STD.vmtx
/vmfs/volumes/465eeda7-2a63d436-724b-011aa0289d15/RHEL5/RHEL5.vmtx
