vCenter and host build numbers

This is based on Carter Shanklin’s PowerShell snippets to query VC and ESX build version numbers.

This script loops through the list of vCenter servers, and gets their version and build info, as well as the version and build info for it’s connected hosts.

# Array of vCenter Servers
$arrVCenterServers = @("server1","server2","server3")

# Create empty arrays for the results

	$objVCenterServer = Connect-VIServer $strVCenterServer

	# Version info about the VC you are connected to

	# Disconnect from the VC server
	Disconnect-VIServer -Confirm:$False
}

# Output the VC results (can be modified to output to a CSV with Export-CSV)
$arrTableVCs | Select-Object Name, Version, Build | Sort-Object Name

# Output the Host results (can be modified to output to a CSV with Export-CSV)
$arrTableHosts | Select-Object VCServer, Host, Version, Build | Format-Table
