It really depends on what you're doing and your objectives.

Consider RAID 1.  Mirrored disks.  Lose one, but your data is on the 
other.  Nothing lost.

Now, not exactly the same, but perhaps consider cluster nodes as 
mirrored systems.  Lose one, and others continue with the processing.

You don't get that when you have to recover to a passive system.

So the question remains, how important is such a capability to you?  If 
not important, then perhaps a VMS cluster is not for you.
