3 r640s connected to 3 luns on unity 380

We have server a, b, c  and lun0 1 and 2.

 

All three hosts have acces to all 3 luns.  If I am on server a and add a file to lun0 server b and c dont see it.  And then within minutes the data is corrupted.  This is a new setup 

 

any ideas?  I worked with prof services to set it up and he seems baffled

Just for the docs..... the Unity can provide FILE services... where multiple devices can have access to the same "\\SHARE\" or offer BLOCK Storage. If you configure access for more than one Host to a Block LUN than you need Hosts which runs a Cluster Filesystem on it.   vSphere ESXi with its VMFS is one of theses.. but  others are also exists.

If you just use a non cluster FS than the other hosts will damage the filesystem because they where not away of changes from the others and also locks want work.
