today I wanted to upgrade NOS on one of our clusters from 4.1.x to 4.6.3 which worked perfectly fine for another cluster.
The first CVM was updated successfully but the next CVM Update failed. (Maybe due to connectivity issues to the host.)
upgrade_status says, that the node is upgrading right now, but in fact the CVM is powered off and won't boot. After it displays the following information it reboots fails again and after the second reboot it stays shut down.
Is there a simple fix for this or do I have to open a support ticket?
EDIT: it seems like the update process tried to shut down this cvm but got a timeout and now the update is somehow stuck. Can I somehow restart the upgrade process or manually update this CVM?

Hi All, it seems it was a known problem in v5.5.3 and Nutanix issued a fix on the 22nd June 2018 - it is fixed in AOS 188.8.131.52
I hope this helps.
