Error - No hosts with hardware version '9' and datastore(s) which are powered on and not in maintenance mode are available

Hey again,

Another SRM question. While testing a recovery plan i'm getting the following error:

Error - No hosts with hardware version '9' and datastore(s) snap-xxxxxx which are powered on and not in maintenance mode are available

I'm getting it on a template! all host in the recovery site are hardware version 9 and the snapshot are being exposed on the recovery site as it should.
Other virtual machines that reside on the same datastore are being recovered properly

Any Ideas?

Dan.
