fdm vib failed to install automatically on ESXi host post vCenter upgrade
When you try to manually install the fdm vib manually on the host, it says "reboot required due to a pending transaction."
vCenter, ESXi
From esxupdate.log:
Log excerpts: “2023-10-31T14:14:37Z esxupdate: 65935985: LiveImageInstaller: DEBUG: Only reboot-required installations are possible right now as a reboot-required installation has been done.”
Note: Reboot of the host was required for successful installation of FDM vibs post a former change on ESXi host that required a reboot.
Reboot the host to complete the installation of FDM agents and re-configure HA.
Preventive Measure:
If there were any changes done on the ESXi host (installation/removal of Vib’s) which warrants a reboot. Please take necessary measures to mitigate the issue. This will ensure that fdm vib is pushed to the ESXi host without requiring a reboot.
