One or more of the Drives could be on it's way out. You can get a Link to the HD Makers Testing Utility from here

As for the second part of your Question this happens when things are not stopped before Dismounting and remounting. The Partition Tables get corrupted and become unreadable so the computers think that the HDD are actually Blank because the Partition Tables are unreadable.

SAN devices can be very complicated to configure and maintain. These questions that you raise might be better answered by the support team of the manufacturer.
