The ESXi host was originally deployed with a custom image but was later upgraded using a standard ISO. In such cases, vendor-specific VIBs are not updated to versions compatible with the target ESXi release. As a result, if any incompatible VIBs remain, the HA configuration may fail due to the FDM VIB installation being blocked by these incompatibilities.
When performing upgrades, it is advised to use the appropriate custom ESXi image.
To remediate the host, apply one of the following workarounds:
Upgrade using the correct custom ESXi image, or
Remove or update all incompatible VIBs to versions that are compatible with the target ESXi release.
Note: All incompatible VIBs must be addressed in a single operation. Partial remediation may result in errors due to remaining incompatible VIBs.
Example:esxcli software vib remove -n dell-configuration-vib -n dellemc-osname-idrac -n qedentv-ens -n qedf -n qedi
If the VIBs are provided by the OEM, it is recommended to consult the server hardware vendor to confirm the purpose and usage of each VIB. If any VIBs are not actively used by the hardware, they can be considered for removal. For those that are required, the vendor should be contacted to obtain compatible driver versions for the target ESXi release.
