CSV's empty on certain HOSTS

We have 10 physical Hosts, they are as follows:

HP DL385 G7 (AMD Proc)

-      Hypersrv01

-      Hypersrv02

-      Hypersrv03

-      Hypersrv04

-      Hypersrv05

-      Hypersrv06

HP DL385 G8 (AMD Proc)

-      Hypersrv07

-      Hypersrv08

-      Hypersrv09

-      Hypersrv10

I currently have 5,6,7,8,9 & 10 Clustered, unfortunately, on 5 & 6, not all of the CSV’s are available and we are having trouble figuring out why.  This is fine on 7, 8,9 & 10. 

Any ideas?

Thank you,
