Find the BIOS Version of an ESX Host
Posted on September 22nd, 2009 4 commentsA while back I needed to confirm what level of BIOS firmware a bunch of ESX hosts were at. Unfortunately I ran out of time to look properly, but today I discovered how to do it whilst looking through the VMware SDK for something else. Turns out it is very simple:
$VMHost = Get-VMHost 'Server01' | Get-View $VMHost.Hardware.BiosInfo
This will give you results along the lines:
BiosVersion ReleaseDate DynamicType DynamicProperty

Hi Jonathan,
I tried the above on a few of my HP servers – no bios fields were populated … have checked the Hardware fields in PowerCli it would appear HP don’t seem to populate this field (and Serial Number either) at least on the ones I tried (bl460, bl680, dl380).
Thought I’d let you know if anyone else comes up with similar missing fields …
Thanks
Matt

Hey,
Thanks for the feedback and info. It’s a shame HP is not populating that info. I was running the commands against Dell 2950’s.

Jonathan – I checked my test vSphere boxes and it looks like it has fixed the bios field population .. I can now see bios revision on both a 460c blade and 380 G5.
Cheers
Matt
