VMware Tools Part 2 – Versions and Changes by Manfred Hofer March 31, 2016 In part 1 I covered the overview about VMware Tools (What is VMware Tools, What are the 3 types of VMware Tools, What is the differences between them etc.). File Name: VMware-VMvisor-Installer-5.5.0-1331820.x86_64-Dell_Customized_A00.iso. Download Type: HTTP. Installation: To install VMware ESXi with this downloaded.ISO file using CD-ROM method, you need a CD-R or CD-RW and appropriate software to create a CD. Follow your CD writing software vendor's instructions to create a CD.

This can be easily achieved using Update Manager but even though this post is going to explain the manual process to upgrade your ESXi host using esxcli command. Download ESXi 5.5 Update 1 from the VMware patch download page and download the ESXi 5.s update 1 zip file. Take a look at post Search and Download VMware Patches.

Once ESXi 5.5 update 1 is downloaded, upload the update-from-esxi5.5-5.5_update01. zip file to your datastore of the ESXi host and verify the file is visible in the directory inside the datastore .Before upgrading to ESXi 5.5 update 1, verify the build version of our ESXi host. which is VMware ESXi 5.5.0 (VMKernel Release Build 1331820)

You can verify the build version of ESXi 5.5 from the command line using the below command:

Vmware Esxi 5 5 Versions

vmware -v

Execute the below command to install the ESXi 5.5 update 1 :

esxcli software vib install -d /datastore/directory/update-from-esxi5.5-5.5_update01. zip

Once ESXi 5.5 update 1 is installed on the ESXi host, You can see the message “The update completed successfully, but the system needs to be rebooted for the changes to be effective”. Reboot the ESXi host. Once ESXi host is back after the reboot, verify the ESXi version after upgrade to ESXi 5.5 update 1.

Build version for the ESXi 5.5 update 1 is VMware ESXi 5.5.0 (VMkernel Release Build 1623387)
