Installing MSA2000 MPIO drivers under Hyper-V R2 Standalone


This caused me a few headaches the other night.

 

Start off by enabling MPIO support from the command line – “start /w ocsetup MultipathIo” does the trick;

Next run up the MPIO control panel applet – simply “MPIOCPL” from command prompt

On the subsequent window, browse to “DSM Install” and type the path to your hp MPIO driver file. Then click install. It will prompt you to reboot, do so.

Run a disk scan and you will see MPIO isn’t working yet. *sigh* back into MPIOCPL, and go to “Discover Multi-Paths” – you will see a new device here now (that wasn’t there before);

imageClick the Device Hardware Id and click “Add”. Again, reboot when prompted and run a re-scan when the server is back up – and voila you should have MPIO presented LUN’s!!!
