vSphere ESXi firmware & driver alignment

Recently whilst troubleshooting a vSphere cluster issue, I had to align the firmware and driver on each ESXi host in the cluster. The following commands help to gather the required information. Of course you could easily create a PowerCLI script to cycle through each host and run these commands if you are inclined:

Bios Version:
smbiosDump | grep "Primary Ver"

NIC Driver type:
esxcfg-nics -l
NIC Driver & FW version:
esxcli network nic get -n vmnic

HBA Driver type:
esxcfg-scsidevs -a
HBA Driver & FW version:
vmkload_mod -s bfa |grep Version
