Ok and last thing about the auto-failover limitation in this case (because it's becoming a little bit complicated for my understanding ).
I dont understand why i cant attach my clustered volumes with the failover virtual IP and in same time attach independant volumes (non redundant) using the physical array IPs ?

The aim is to keep some storage space seperated from synchronous tasks but keeping autofailover on clustered volumes would be great. Don't you think that would be a valuable function ?

Best Regards
