Usually the patching of VMware vSphere Cluster is done through vSphere Update Manager (VUM), but for this you need vCenter. In case you’re managing single ESXi host without vCenter, you might be interested to know how to patch the ESXi host from the command line.

No need to say that I’m supposing that you don’t use vCenter in purpose, and so that you want to patch your ESXi 5 standalone host or that you want to patch VMware ESXi 5 Free version without VUM.

Otherwise it’s much more convenient using VUM which can automate the patching process by using vMotion to move the running VMs to other hosts inside of the cluster, putting the host which you want to patch into maintenance mode and do the restart.

The patching of VMware ESXi 5 is quite straightforward process, but there is one condition: SSH access

The SSH access can be easily enabled by using the VMware vSphere client through the GUI.

Putty is the most known SSH client.

Run this command and wait, because the decompression and installation take some time……

esxcli software vib install -d /vmfs/volumes/<YOUR VOLUME>/<NAME OF PATCH FILE>.zip

In my case, I executed this command:
