Upgrade ESX 5.5 to 5.5 Update 2

See my previous post (here) for more details. 

1) Shutdown all running VMs

2) Put ESX in maintenance mode:
> vim-cmd /hostsvc/maintenance_mode_enter

3) Perform the upgrade:
> esxcli software profile update -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml -p ESXi-5.5.0-20140902001-standard

4) Reboot

5) Exit maintenance mode:
> vim-cmd /hostsvc/maintenance_mode_exit
