When using Media Browswer, (premiere or prelude) if I click on our XSAN root on the left, the 'View as:' switches to 'XDCAM-HD' and the program freezes (pinwheel). I can import items from the SAN and play footage just fine using the import dialog in Premiere or drag and drop, so it is not entirely a SAN access issue. It seems to be an error when MB tries to analyse the file structure, and gets stuck - my best guess.
It is a 16TB SAN. CS6, updated.
Issue occurs on multiple SAN connected machines, including a freshly wiped, newly installed computer.
