When creating a LUN for a new MSCS, here is the methodology;
Just a quickie to remind myself of some NetApp settings 🙂
LUN Path = qtree object path (click through)
LUN Name = volume name.lun
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);
