Esxi upgrade 4.1

Upgrade from ESXi 4.0 to 4.1

Hello,

You must use the CLI to do that.

Install it, launch the CLI prompt, put the ESXi host on maintenance mode and run this command :

vihostupdate.pl -server yourhost -i -b "upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip" -B ESXi410-GA-esxupdate

After a while you should have this :

Please wait patch installation is in progress ... Host updated successfully.

launch this one after :

vihostupdate.pl -server yourhost -i -b "upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip" -B ESXi410-GA

Please wait patch installation is in progress ... The update completed successfully, but the system needs to be rebooted for the changes to be effective.

Note : the upgrade file must be accessible from the Host.

Now check that everything worked :

vihostupdate.pl -server yourhost -query
