Mark, Well, assuming that you are running the same IOCDS in both locations, only the 17 bits of IO serial number in the middle the WWPNs would be different. That would impact zoning and lun masking at the DR site. But is that really the biggest problem? NPIV WWPNs aren't put into any of the Linux configuration files. Isn't it a bigger problem that the WWPNs of all of the storage devices at your DR site are different? Or is there a way to tell a shark to use certain WWPNs?

What needs to happen there?
