Upgrading ESXi 4 to 4.1
From
Upgrading a standalone ESXi host to the 4.1 release requires the use of vSphere vCLI - the host update utility cannot be used.
Contents |
Requirements
- vmware vCLI (which is installed on Windows, and note needs a reboot after installation)
- vmware ESXi update package ZIP file, which can be downloaded from the downloads section from vmware.com after registration
Method
- Download the update package, named upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip at the time of writing (and about 200MB)
- Install vmware vCLI on a Windows host:
- Connect to the host using the vSphere client, stop or pause any VMs, and enter maintenance mode
- Open a command window and change directory to the vCLI bin folder:
C:\Program Files\VMware\VMware vSphere CLI\bin>
- The update is performed using vihostupdate.pl in two steps:
perl vihostupdate.pl --server [hostip] -i -b [update-file-name] -B ESXi410-GA-esxupdate perl vihostupdate.pl --server [hostip] -i -b [update-file-name] -B ESXi410-GA
- The tasks will appear in the vSphere client if connected (see screenshot)
- Check the update status:
perl vihostupdate.pl --server [hostip] --query
- Restart the host and exit maitenance mode
