Upgrading an ESXi 4.0 server to 4.1

I found the following blog article particularly useful in documenting the steps to upgrade an ESXi 4.0 server to 4.1.

I’d already downloaded to my vCenter server.  I’d also downloaded and installed VCLI 4.1 on the vCenter server too from here.   The following applicable steps in the article above.

  • Power off your VM’s and put the host into maintenance mode
  • Change your current directory to C:\Program Files\VMware\VMware vSphere CLI\bin
  • From the vSphere CLI prompt
  • –server host name or IP address -i -b location of the ESXi upgrade ZIP bundle -B ESXi410-GA
  • So in my case (don’t forget the .pl in\Program Files (x86)\VMware\VMware vSphere CLI\bin> –server esxiblade2 -i -b -B ESXi410-GA

After rebooting the ESXi server it was then running at ESXi 4.1 !
