Hello Oriol,
I don't think you can have more than one system datastore, but I could be wrong 
about that.  But, unless I misunderstand your goal, I don't think you need to 
have more than one.  You should simply be able to define 2 datastores and 
associate each with the cluster.  I have a similar setup to what you describe, 
I have a cluster that has 2 different NFS datastores, a local file datastore, 
and an iSCSI datastore.  I can use images from any/all datastores in a single 
vm (though I actually don't).

Hope that helps,
gary

Subject: [one-users] Two System Datafiles in the same cluster

Hi,

somebody knows if it is possible to have two system datastores in a cluster and 
create VM in the same host but in different datastores?
I've my default SYSTEM_DS="101" in the cluster, I've tried to add to the MV 
template to change the datastore which the vm is created:
REQUIREMENTS= "DATASTORE_ID = \"103\""
(I don't know if this is correct)
  
But the VM does not boot, and is in pending state. Somebody know if is possible 
or I have to create two clusters one with the datastore 101 and another one 
with the datastore 103?

My idea is to have one cluster with one NFS datastore and another local-file 
datastore.

Thanks!
