VMware: How to rollback ESXi 5.1 to 5.0

October 3rd, 2012 7 comments

VMware vSphere ESXi 5.1 was released last month, after upgrading my hosts I had some really annoying issue’s, I couldn’t connect my iSCSI (QNAP) datastores and the hosts failed with a PSOD.. once I checked the HCL at the VMware website I saw that my HP DL360 G5 isn’t supported anymore.. time to rollback the latest installation.


Solution:

(Re)boot the host and press R to start the Recovery Mode..

Installed hypervisors:

HYPERVISOR1: 5.0.0-623860
HYPERVISOR2: 5.1.0-799733 (Default)

CURRENT DEFAULT HYPERVISOR WILL BE REPLACED PERMANENTLY
DO YOU REALLY WANT TO ROLL BACK?

 

Press Y to start the roll back

Result:

The host is downgraded and back online again with VMware vSphere ESXi 5.0.0
