As probably most of us are already aware that auto start VM’s option gets disabled when ESXi 5.0 U1 is installed and if you wish to rollback to previous version it is possible.
Roll back using DCUI
This is the supported roll back option.
- Connect to the host using hardware remote console (ILO,DRAC, RSA, etc..
- Reboot the ESXi hosts
- Press SHIFT+R to enter into recovery mode
You will be prompted with a new screen with the Hypervisors installed. One would be the default which is Update1
- To confirm Roll back Press Y
- Server will be rebooted and reverted to the previous version of ESXi 5
