HOW TO: Upload an ISO image to a VMware datastore for use with VMware vSphere Hypervisor 6.7 (ESXi 6.7) using the vSphere Host Client, and checking its MD5 checksum signature is correct.  It's a good idea to compare checksums because many installations fail because of a corrupt iso image.

In my previous Experts Exchange Articles, most have featured Basic and Intermediate VMware and Virtualisation Topics. 


If you would like to read my Basic VMware articles, they are listed at the end of this article for your convenience.


In this series of basic VMware articles for the Novice, I'll be showing you the basic VMware skills required to install, configure and deploy virtual machines using VMware's FREE VMware vSphere Hypervisor (ESXi).


There are other third-party tools, that can be used to upload ISO image files, these include:-

 


The above applications, require additional installation and configuration, in this article, we will use the VMware Host Client using a web browser.

 

1. Connect to the VMware vSphere Hypervisor 6.7 (ESXi 6.7) or vSphere vCenter Server using the vSphere Client


Please refer to my EE article on HOW TO: Connect to the VMware vSphere Hypervisor 6.5 (ESXi 6.7) using the vSphere (HTML5 Web) Host Client 6.7. Please note the default username for ESXi login is root!



 Once connected to the "default hypervisor home page", click the Host icon, to see the Host server's Inventory.

 


Click the datastore, in this tutorial it's esx001_local1_vmfs6



The datastore object will be displayed.



Click Datastore browser to browse the datastore.



I like to contain all my isos, in a folder or directory. 


Click Create directory



Enter a suitable name for the folder or directory. e.g. isos and click New directory.



Select and Double-Click the isos folder to change folders.



2. Uploading the ISO image to the datastore 'esx001_local1_vmfs6'


Click Upload and browse to the location of your iso you need to upload. In this tutorial, my isos are located on my local computer E:\isos. I'll be using a Windows 10 Consumer iso from Microsoft.



The progress bar shows the progress of the upload.



the windows_10_consumer_editions_version_1903_x64_dvd_b980e68c.iso.iso has been successfully uploaded to the datastore.


 

3. Confirming the upload of the ISO image file has been transferred successfully using the MD5 checksum signature


To complete the following step SSH must be enabled and running on your VMware vSphere Hypervisor 6.7 (ESXi 6.7) host server, if SSH is not running you will receive a connection refused message.


To Enable SSH on your VMware vSphere Hypervisor 6.7 (ESXi 6.7) host server, please see my EE Article HOW TO: Enable SSH Remote Access to a VMware vSphere Hypervisor 6.7 (ESXi 6.7)


Connect to the VMware Hypervisor ESXi server via SSH. Using PuTTY a free telnet and SSH client or another SSH client Login and Connect to the VMware Hypervisor ESXi server, using IP address or hostname of the VMware Hypervisor ESXi server, using root username and password credentials. This can also be performed if you have access to the console.




You will need to change folder or directories to the location of the iso image file. The VMware VMFS datastores are mapped here /vmfs/volumes. Use the following command to change to the datastore1 datastore and isos folder.


cd /vmfs/volume/<datastore name>/<folder name>

example :- cd /vmfs/volumes/esx001_local1_vmfs6


type


cd /vmfs/volumes/esx001_local1_vmfs6 

in the SSH session window.



When you have successfully changed folders to the location of the isos image file which has been uploaded, use the following command to check the MD5 checksum signature.


md5sum <filename>


example md5sum windows_10_consumer_editions_version_1903_x64_dvd_b980e68c.iso.iso



type 


md5sum windows_10_consumer_editions_version_1903_x64_dvd_b980e68c.iso.iso

in the SSH session window. 


After several minutes, and the time taken, depends on the size of the ISO image file, and speed of the host processor and storage, an MD5 checksum signature will be displayed. The number displayed next to the filename - 8ba0e81b276d9052e8538deb0cf6c7d0 - is the MD5 checksum signature. Compare this number with the original number computed before the ISO image file was uploaded if they match, the transfer was successful. If they do not match, repeat Step 2 above.


Congratulations, you have successfully uploaded an ISO image to a VMware datastore for use with VMware vSphere Hypervisor 6.7 (ESXi 6.7) using the vSphere Host Client, and checked its MD5 checksum signature is correct.
