Check that driver file versions match on all your cluster nodes via Powershell

Check that driver file versions match on all your cluster nodes via Powershell

This is more of a proof of concept, but I've used it with success internally.  Take it and do with it what you want.  Many thx to Brandon who did the "heavy lifting" when I got stuck!

Overview:

Ever run into cluster issues and wanted to see if the driver file versions matched on all the nodes of the cluster to rule out a mismatch on a driver level?  Well I did!  The basic gist is that you can show all the file versions for each node by just running the script against a node name.  If you want to see only the drivers that don’t match then you’d use the pipeline with where-object (?).

Typical output:

When All drivers match:
PS C:\Debuggers> Test-MSCluster.ps1 ServerSQL11 | ?{!$_.IsSame}
Getting Nodes via WMI
Getting the drivers on: ServerSQL11
Getting the file versions for the drivers on: ServerSQL11
Getting the drivers on: ServerSQL12
Getting the file versions for the drivers on: ServerSQL12
PS C:\Debuggers>

One Mismatch:
PS C:\Debuggers> Test-MSCluster.ps1 ServerAX | ?{!$_.IsSame}
Getting Nodes via WMI
Getting the drivers on: ServerAX
Getting the file versions for the drivers on: ServerAX
Getting the drivers on: ServerBX
Getting the file versions for the drivers on: ServerBX

FileName                                                                   ServerAX                                                                 ServerBX
--------                                                                   ----------                                                                 ----------
rmcast.sys                                                                 6.0.6001.18000                                                             6.0.6001.18069


Many nodes, many mismatches:

***Note:  This script is not fast, as it is getting the file versions for every driver (*.sys)  on each system,  I'd highly suggest not running this over the WAN...

  • Hey eltate, you need to be running Powershell v2.

  • Hey elate:

    The -Authentication was put into v2 to help with this issue.  You cannot use get-wmiobject in POSH v1 to connect to namespaces that require packet privacy (see my earlier post on this subject).  You'd need to use [wmisearcher] or the .NET framework and then set the authentication in there.  Sorry.  It CAN be done though, just a bit more work.
