Definition
- An inbox driver is one that is delivered and installed with ESXi software.
- An async driver is the third-party vendor driver certified by VMware. It does not come bundled with ESXi software and is usually downloaded from VMware.
Why we care
- When inbox and async drivers are present, they are both displayed as installed. However, only one is loaded
- The inbox driver is not removed when an async driver is installed, which results in multiple drivers for the same device being installed
- Multiple drivers can be installed but one is loaded and used.
Determine which drivers are installed
- esxcli software vib list | less
- esxcli software vib list | egrep <driver_string>
- If the system has an inbox and async driver installed, the above egrep command displays more than one output
Determine which driver is actively being used
- esxcfg-info | less
- Look at the Version under the module
- The name and the version of the storage driver corresponds with the second drive in the output of the esxupdate query command
- For network drivers
- ethtool -i vmnicX
- Identify the vmnic # of the associated NIC
- esxcfg-nics -l
- esxcli network nic get -n vmnicX
