After the ESXi rollback from version 6.7, the new tools-light VIB does not revert to the earlier version. As a result, the VIB becomes incompatible with the rolled back ESXi host causing these issues. Ref https://docs.vmware.com/en/VMware-vSphere/6.7/rn/vsphere-esxi-vcenter-server-67-release-notes.html
Because of the above behavior the “vmware-fdm” vib on the ESXi fails removal, preventing the installation of the latest FDM vib from vCenter causing the vSphere HA to fail with error “vSphere HA agent cannot be installed or configured”
You might get below errors while configuring vSphere HA:
— vSphere HA configuration fails at 99% as Operation timed out
— The ESXi will have “vmware-fdm” of a different version and will fail to uninstall, preventing the installation of the latest FDM vib from the vCenter to manage the ESXi.
— vmware-fdm vib removal will fail with error message as below:
[root@esxi8:~] esxcli software vib remove -n vmware-fdm
VIB VMware_locker_tools-light_10.3.2.9925305-10176879 requires esx-version >= 6.6.0, but the requirement cannot be satisfied within the ImageProfile.
Please refer to the log file for more details.
To resolve the issue:
- Find the current version of the ESXi using the command vmware -vl
- Download the VMware tools vib from https://my.vmware.com for the above build
- Upload the vib or the zip to the ESXi and install the “VMware-Tools” for the above build using below command:
[root@esxi8:/vmfs/volumes/Sysops] esxcli software vib install -v “/vmfs/volumes/Sysops/VMware_locker_tools-light_6.5.0-10.3.5.10430147.vib”
Installation Result Message: Operation finished successfully. Reboot Required: false VIBs Installed: VMware_locker_tools-light_6.5.0-10.3.5.10430147 VIBs Removed: VMware_locker_tools-light_10.3.2.9925305-10176879 VIBs Skipped:
4. Now remove the vmware-fdm vib using the following command esxcli software vib remove -n vmware-fdm, the vmware-fdm should now uninstall successfully
NOTE: Perform the above step manually on all the affected ESX
5. Configure vSphere HA
