Command Line VMWare ESXi Upgradation to 7.0 U3a

Hey guys, In this post we are discussing about a quick VMware ESXi upgrade method to ESXi 7.0 U3 using command-line interface (CLI)/Putty. And which allows you to quickly download and upgrade your ESXi host if you are not using vCenter server and the host has no internet access.

Before starting, Please make sure you have done backup of your VMs.

Build Details

Note: This is a critical update.

Step 1: Offline Bundle download

Download the software from VMWare Customer portal. You need to create an account for login and it's easy. After login, please go to product patches page. And select the software patch as shown in the figure and click download now.


Step 2: Upload Zip file to Datastore

You can upload using VMware Client web interface. 

Go to storage section in VMWare Client and click on Datastore browser and upload the file to a folder/or to root folder of datastore. 



Make sure you have a VM's data backup.


Step3: Enable SSH for Host Manage

Go to Hosts> Manage>Services>TSM-SSH. And right click to start the service.


Check the connection to server using putty/SSH Client. For downloading putty, click here


Type hostname/IP Address and Click Open. A connection to the server starts and prompts for the login credentials. Please use server login credentials. While typing password, we can't see it in the CLI. So don't be afraid and type the password(Don't Copy).

And you will get a connection to Server.

Step4: Change Server to Maintenance Mode

Shut down all your VM's before entering maintenance mode. You can set maintenance mode via CLI or Web Interface.

Web Interface:

Right Click on host and click "Enter Maintenance Mode".

CLI/SSH Client:

Type/ copy command to putty;

vim-cmd /hostsvc/maintenance_mode_enter

For verfying, please type/copy;

vim-cmd /hostsvc/hostsummary | grep inMaintenanceMode

If the server is in maintenance mode, the a true will display.

Step 5: Searching Profile list

Navigate to the directory on the datastore where the patch file was uploaded to and verify that the file exists by running these commands;

esxcli software sources profile list -d /vmfs/volumes/<yourdatastorepath>/VMware-ESXi-7.0U3a-18825058-depot.zip

This will display the list of profiles in bundle. In our case, we pick the standard because I want the  VMware tools package present on the host. The other one with no-tools is the one normally use for Autodeploy.

Step 6: Updating OS

Enter this command to update ESXi;

esxcli software profile update -p ESXi-7.0U3a-18825058-standard -d /vmfs/volumes/<yourdatastorepath>/VMware-ESXi-7.0U3a-18825058-depot.zip

Note: Use the update command is the recommended method as it preserves VIBs. (The “install” command wipes things out). Using this command applies all of the newer contents in the file, including all security fixes.

Wait for a minute and after the update you will get a message in putty CLI as shown below;


Step 7: Reboot ESXi Host

You can reboot ESXi host using web interface or by typing reboot in putty CLI.

Step8: Exit Maintenance Mode

Exit maintenance mode by logging to the Web interface. And you can see the ESXi host was updated with a new build number.

Link State Routing Protocol

Link state routing is a method in which each router shares its neighborhood’s knowledge with every other router on the internetwork. In this algorithm, each router in the network understands the network topology and then makes a routing table depending on this topology. Each router will share data about its connection to its neighbor, who will, consecutively, reproduce the data to its neighbors, etc. This appears just before all routers have constructed a topology of the network. In LSP, each node transmits its IP address and the MAC to its neighbor with its signature. Neighbors determine the signature and maintain a record of the combining IP address and the MAC. The Neighbor Lookup Protocol (NLP) of LSP derives and maintains the MAC and IP address of every network frame accepted by a node. The extracted data can support the mapping of MACs and IP addresses. The link-state flooding algorithm prevents the general issues of broadcast in the existence of loops by having every node mainta

HP NETWORK SIMULATOR: A COMWARE OS LEARNING TOOL

  Comware v7 is a network operating system that runs on HP high-end network devices. The HP Network Simulator is an ideal Comware v7 learning tool, which allows users to create, configure, and connect simulated networks. Benefits Beginners  – The HP Network Simulator tool is helpful for users who are new to networking and want to learn how to configure network devices (switches, routers), various topologies, or different routing and switching protocols and features. Experienced users  – The HP Network Simulator learning tool is helpful for users who have experience with non-HP networking devices and want to learn the Comware CLI and features. Extra devices  – Users can create devices using the HP Network Simulator and use them with their physical devices to configure and test topologies that aren’t configurable with just the physical devices they have. For example – A user wants to configure OSPF using 3 or more devices but has only 1 physical router. User can create 2 or more routers
