Horizon View Instant Clone & Nutanix Firmware updates....Sanity check..
We have been running our Horizon View environment on Nutanix a little over 6 months, and I'm ready to do my first round of disk/BIOS, etc firmware updates. My main concern, is since we are utilizing Horizon View instant clones, there is a powered on "parent image" on each host...We are running View 7.5, and I know in previous versions, there was an attribute called "Instant Clone maintenance" that you changed the value to a 1, and it would shut down and delete that parent image, disallowing any desktops from being provisioned on that host allowing you to place it in maint mode, and do your business. I need some clarity (and a sanity check!) on how to allow (or if I don't use LCM) to perform these necessary firmware updates without bringing my View environment down...This environment is used 24x7 and cannot withstand an outage..Please show me your wheel, so I have no need to re-invent!! Thank you community!

mjg, Currently the best way to do the nodes that are running your instant clones is individually. VMware has made it a bit easier, as you'll notice each node (in the vSphere web client) has a custom attribute "InstantClone.Maintenance", and the current value should be 0. My steps to upgrade firmware, or anything that you need to put the host into maintenance mode are below:
NOTE: if you have ANY nodes that require SATADOM upgrades, you HAVE to apply them on every node before any other firmware shows as available.
Let me know, i'm happy to answer any other questions!
View original- Edit the value for "InstantClone.Maintenance" to 1
- After a few minutes, vCenter and Horizon View will see that value, and shut down/delete the cp-parent VMs on that host, and the value will change to 3
- Once you see the cp-parent VMs are gone, you can go into Prism and go to LCM, once you have performed an inventory, you should be able to put a check next to the host you want to upgrade (ONLY CHECK THE HOST YOU WISH TO UPGRADE!).
NOTE: if you have ANY nodes that require SATADOM upgrades, you HAVE to apply them on every node before any other firmware shows as available.
