Access problems to the CSV

dear all,

I have a 4 node cluster running on widows 2008 r2 connected to a storage where I have 23 VMs.

I can´t have all 4 nodes browsing the CVS (ClusterSorage), just 2 can do at a time. Or the 2 old machine (NODE1 and NODE2) or the new 2 machines (NODE4 and NODE5).

When the NODE 1 and 2 can access the storage and browse the ClusterStorage the NODE 4 and 5 can´t acess them. 

Can someone tell me what could be the problem, because on the OS level the storage a available.

See the printscreens for more details.

Regards,

NC\
