This is a step by step procedure to update offline bundle zip on standalone Esxi host using command line without vCenter. I was updating few of my VMware ESXi servers in my home Lab environment. There were few ESXi hosts in the lab were standalone and not connected to any vCenter server. On the standalone server I was running Virtual Machines (It was not possible to move them), which I shutdown or suspended as per the maintenance window (Best way take backup of VMs). All my VMs are either suspended or Shut Down. 

Download ESXi server latest depot zip patch bundle file from VMware website.

Upload this Zip file on the Esxi Datastore using ESXi Host Client, Expand Storage go to Datastore and click Datastore Browser, Select the folder and Click Upload button to upload zip file as shown in the below screenshot. You can monitor the status of upload, click refresh once the process is completed to see the file details.

Next Enable secure shell (SSH) on Host by right click or click Actions then Services.

You can check whether SSH is enabled by clicking Manage >> Services >> TSM-SSH. Here you can start and stop services.

Login to ESXi server using ssh tool. Use below command as highlighted in the Red. Change the directory to ISOs folder on datastore (Where I uploaded zip file). Verify zip bundle file exists with ls command.

Next I am going to use localcli command (You can also use esxcli). Using localcli list all the profiles in depot esxi zip bundle. I will use no-tools profile to update ESXi. Using localcli software profile update command and providing depot and profile parameters. you can see it starts updating ESXi process from zip depot profile, it takes some time for update. After successful update installation, reboot is required to take change to be effective.
