vCenter Appliance Update Buttons Greyed Out

Although the following process in itself will not enable those buttons directly again, it will allow you to perform an update of the appliance from a command line… which should enable those buttons again after the update is completed.  This method should also only be performed for a minor update to the appliance… I’ll write a slightly different post on the process to upgrade to a major release:

  • Download the minor release that you wish to upgrade to, as an ISO
  • Mount the ISO to the console of the vCenter Appliance
  • Log onto the web interface of the vCenter Appliance:   https://webaddress:5480/
  • Switch to the ‘Update’ tab and then click the ‘Settings’ button
  • Make sure that the ‘Use CDROM Updates’ option is selected and click ‘Save Settings’
  • Using Putty, connect to the vCenter Appliance (using the root username and password previously used for the web interface)
  • Type:
    /opt/vmware/bin/vamicli update --check
  • You should now see an update similar to below:
  • Next type:
    /opt/vmware/bin/vamicli update --install latest --accepteula
  • This will now present you with a screen similar to below:

This update will actually now take approximately 20 minutes to complete, the appliance will then reboot and you should then be presented with the new version.

Please note that you should log back onto the appliance and perform a reboot of it before the new version takes effect.

About the Author


I have been in IT for the past 15 years and using virtualisation technologies for around the past 8 years. I started, as quite a lot of people do, working with PCs after playing with such iconic systems like the ZX81, ZX Spectrum and then progressing through 386s, 486s, Pentiums etc. After being headhunted at sixth form to work for a small company based around Hertfordshire, UK. I began working with small businesses and gaining a lot of hardware experience. Three years later, after helping to increase the size of the business, I needed to gain exposure to a larger environment to progress my own career. I joined a large manufacturing company around Electronic Test and Measurement which progressed my skills onto more PC work, hardware work and then onto Server Operating Systems. I progressed again onto a consultancy company based in Reading, UK. Initially working as an engineer performing hardware / software installations for larger companies contracted out to the consultancy company, I moved up into a Consultant position continuing my travel across the UK assisting and providing solutions to companies. I finally moved on again to my current position, working back in Hertfordshire, UK. Again working for a large manufacturing company, this time with over 50,000 users worldwide. I am responsible for the datacenter hardware, the storage environment, the vmware environment and also implementing their new Citrix XenApp farm. My days are busy but also productive, its a friendly environment and in my four years of being with the company, I have seen many changes in technology and infrastructure in use within the company. About the site I started this site as I had been thinking of having more of a presence on the web for a while. On a daily basis, I perform tasks and use tools that others may not use or may not think to do and therefore I thought that I would share some of these experiences and tips with others to help with their day to day work. Currently, my main focus of work is around VMware and Veeam Backup & Replication but hopefully as my tasks progress, I’ll be able to share useful bits of information about other areas of IT as well.
