Hello, pedrocm2986.
"Virtual Disk Not on Preferred Path" is your machines way of saying your server is accessing data through an alternate route. So, either there is something wrong with the first route, or it can't find the first route. 9 out of 10 times that I've see this error, especially with the SAS version of the MD3200, it comes down to a cabling issue. Whether that means a misplaced cable, or a failing cable.
I would verify the cabling first. Here's our deployment guide, that will give you explicit instructions for cabling: (starting on about page 13) downloads.dell.com/.../powervault-md3200_Deployment%20Guide_en-us.pdf
Go through this first. If it comes to needing to swap some cables, I do NOT recommend doing this 'hot'.
You'll need to bring the machines down in order to swap the cables.(shut down server first, then storage and when you're booting, boot the storage first, then the servers)
Tell me how that goes.
