How to show HBA/NIC driver version

How to find the version of HBA or NIC driver on VMware ESXi?

Let's start with HBA drivers. 

STEP 1/ Find driver name for the particular HBA. In this example, we are interested in vmhba3.

We can use following esxcli command to see driver names ...
esxcli storage core adapter list

So now we have driver name for vmhba3, which is qlnativefc

STEP 2/ Find the driver version.
The following command will show you the version.
vmkload_mod -s qlnativefc | grep -i version

NIC drivers

The process to get NIC driver version is very similar.

STEP 1/ Find driver name for the particular NIC. In this example, we are interested in vmhba3.
esxcli network nic list

STEP 2/ Find the driver version.
The following command will show you the version.
vmkload_mod -s ntg3 | grep -i version

You should always verify your driver versions are at VMware Compatibility Guide. The process of how to do it is documented here How to check I/O device on VMware HCL.
