Today I performed an upgrade of VMware vSphere 4.0 to 4.1. Below the steps I’ve taken to complete this task;
- First download and install the vSphere vCLI from http://www.vmware.com/support/developer/vcli/
- Download the upgrade zip from VMware: Upgrade package for 4.0 to 4.1 or Upgrade package for 3.5 to 4.1
- Connect to the host using the vSphere client, stop or suspend any VMs, and enter maintenance mode
- Open a command window and change directory to the vCLI bin folder (default: CProgram FilesVMwareVMware vSphere CLIbin)
- Execute the following 2 steps to upgrade the host;
- vihostupdate.pl –server [hostip] -i -b [path to updateupdate-file-name] -B ESXi410-GA-esxupdate
- vihostupdate.pl –server [hostip] -i -b [path to updateupdate-file-name] -B ESXi410-GA
- After the upgrade you can check for the installed updates using the command “vihostupdate.pl –server [hostip] –query”
- If the upgrade went successful you must restart the host en exit maintenance mode.
Here is a screenshot the upgrade process;
When you are connected to the host with the vSphere client during the upgrade you can monitor the actions in the Task section;
