Installing Cisco Nexus VEM on an ESX or ESXi host fails with error: Encountered error VibFormatError

Symptoms

  • Installing Cisco Nexus VEM on an ESX or ESXi host fails
  • When executing the command esxupdate -b cisco-vem-v110-4.0.4.1.2.0.80-1.9.179.zip info, you see the error: 

    Unknown bulletin cisco-vem-v110-4.0.4.1.2.0.80-1.9.179.zip

  • When executing the command esxupdate -b cisco-vem-v110-4.0.4.1.2.0.80-1.9.179.zip update, you see the error:

    cisco-vem-v110-4.0.4.1.2.0.80-1.9.179.zip ############################################################################## [100%]
    Encountered error VibFormatError:
    The error data is:
       Filename    - cisco-vem-v110-4.0.4.1.2.0.80-1.9.179.zip
       Message     - Vib is not a valid ar file :('/var/tmp/cache/352769721', 'Not a
                     valid ar file')
       Errno       - 8
       Description - The format of the VIB is invalid.

Resolution

This issue occurs when you use an incorrect installer file to load the Cisco Nexus VEM module.
 
When using esxupdate from the command-line of the ESX or ESXi host, you must use the VIB file and not the ZIP file.
 
Note: The ZIP file must be used only when using the vihostupdate utility.
