In normal situation, VMware driver update is quite simple if you are installing the driver from VMware driver CD/ ISO image by doing the following three steps:

1. Mount the driver CD or ISO image
2. Go to the VMupdates/RPMS/ on the driver CD.
3. Run the "esxupdate update" command.

However,  some vendors may provide VIB or bundle zip files and  just running "esxupdate update" command alone will not work.  You will need run additional options with esxupdate commands and here is how it is done -

For VIB files, run this command:

“esxupdate -b <filename.vib> update”

For bundle zip files, run this command:

“esxupdate update  –bundle <bundle-filename.zip>”

If you are still seeing warning messages, you may want to use with following additional options:

- -olderversion  (it will allow downgrading to older version)

- -maintenancemode  (go into maintenancemode to update)

- -nodeps (no dependency check)

- -nosigcheck (no signature check for installing unsigned driver)

After the installation, use the following commands to verify that the driver is loaded -

"vmkload_mod -l"

To check the driver version, run

“vmkload_mod -s <driver name>”
