Wouldn't touch that configuration with the proverbial barge pole.

And a shadow copy across gigabit Ethernet isn't speedy with what's 
large for OpenVMS but now considered a dinky terabyte or two of hard 
disk or SSD storage.   Yeah, maybe minicopy...

And neither system can boot from the secondary if the local primary 
storage fails, absent reconfiguration as a cluster satellite.

Whether scrounging used HBAs and a switch and some low-end FC SAN 
storage, or scrounging multi-host SCSI and storage, would be cheaper?

More supportable to use the existing disks and the existing RAID 
controllers, and to then configure the shared files...
