Upgrading NetApp SnapDrive for Windows

I was recently asked to perform SnapDrive upgrades against systems in preparation for a NetApp Data ONTAP upgrade.  As I’ve been through this a time or two before, I knew it wasn’t quite as simple as “upgrade” SnapDrive.  I figured I’d share some information that might help someone have a smooth transition when they do it as well. 

The first thing to do is check out the NetApp Interoperability Matrix Tool (IMT).  This will help you determine all of the supported and required versions. 

The next thing you’ll need to know is what versions are supported.  As of Sep 2014, you’ll want to also look at:

  • SnapDrive for Windows – v7.0.3
  • DSM MPIO – v4.1
  • ISCSI Host Utilities – v6.0.2
  • These are the versions you’ll need to support Windows 2012 R2 and ONTAP v8.2.x 7-Mode.

Next, you’ll need to perform an inventory against your systems to determine what versions or even if some of the above tools are installed.  It’s not uncommon to find situations where SnapDrive might be installed, but the other tools may or may not be.  Equally, the versions may or may not be what you’re expecting to find or standardized.  Some of this will depend on who installed what, and when.  Also, you’re likely to run into some older systems such as Windows 2003 or 2003 R2 that are running older versions, and have no upgrade path.   So you may need to come up with a migration or lifecycle strategy for some of your systems.

One of the most frustrating things I’ve found from these events in the past, is that NetApp doesn’t have any log of what is installed.  That’s understandable for the Windows systems, but these tools interact with a NetApp controller.  For systems that don’t – perhaps they don’t any longer, they’re orphaned, they’ve been P2V’d, etc – that’s understandable.  But it would be GREAT if NetApp could be so kind as to log connections from systems and what version of the software is involved.  Something akin to WSUS, but at the controller level – even if just logged to the MESSAGES file.  Either way, that’s just dreaming Smile

The above software is going to have some pre-requisites and requirements.  These include:

  • .NET 3.5 is required – likely, this already is, if you’re upgrading.  If you’re installing clean, then it may not be present. 
  • Various Windows HotFixes, as identified by the installation guides
  • Knowing what your ISCSI timeout settings need to be – my environment has been tested to prefer 190 seconds.
  • I’ve created silent installer batch files for each of the three application installations and a script to verify the installation.  It likely can’t be distributed via SCCM or similar tools at this point, but it’s pretty close.  Expect to see these posted shortly:

HOWTO- Silent Installation for NetApp Data ONTAP DSM for Windows MPIO v4.1

HOWTO- Silent Installation for NetApp Windows Host Utilities 6.0.2

HOWTO- Silent Installation for NetApp SnapDrive for Windows v7.0.3

HOWTO- Verify NetApp SnapDrive for Windows 7.0.3 Installations were successful

I’ve tested these against Windows 2008 R2 SP1 and 2012 thus far, with no issues.

With luck, I can help someone else’s upgrades go smoothly. 

For those that know me – this would be a GREAT place for an obligatory comment like “Ditch the LUN’s, VMDK’s don’t have this issue, and it’s time to stop living in a world with physical constructs, lack of portability, and vendor lock in.”  I like NetApp products, but I like it better when it has VMware on top of it, and the Windows systems don’t have a clue!
