AOS upgrade appears to go well, but my CE three node cluster didn’t complete the first AHV upgrade. Now CVM is off line.  I’m looking a logs but not sure what to look for.

Hi Mark,

The CVM is most likely still in maintenance mode and maybe the host as well. 

to check if the CVM is in maintenance run this on any other CVM “ncli host list”

You will see the hosts (the CVMs) and if it’s in maintenance mode.

If you want to check if the host itself is in maintenance you can run “acli host.list”

It’s also very simple to pull a CVM/host out of maintenance mode: https://portal.nutanix.com/kb/4639
