I'm not sure of your exact setup, but on fibre channel when you have two initiators (the Mac Pro's) with the ability to look at either target (the Promise Raids) and there is no controlling software (like XSAN) to act as a traffic cop to keep the initiators (Mac Pro's) from clobbering the data when writing to the same target (Promise Raids), then this could be your issue.
On fibre channel when you have more than one initiator and more than one target on the same fibre channel switch, you most likely will need to do zoning on the fibre channel switch.
Don't know if this is your problem, but consider it and see if this suggestion helps.

Hello Paradeshi:
It is possible to have multiple computers accessing the VTrak at the same time. If you have a dual port card in your Mac, you will need to connect each computer to both controllers in the back of the VTrak. Each controller will have 4 fiber channel ports. This should allow for both computers to see the volume.
NOTE: The VTrak does not control which computer has read and write access to the volume. If both computers have direct access to the volume, it will cause corruption. You will need SAN software to manage write access to the volume to prevent this. A couple of examples for SAN Software are XSan or SANmp.
The other route you can go is to have a volume isolated to each server. This will prevent the computers from overwriting the same areas of data that can cause the corruption.
If you would like more information about setting up the VTrak to work with multiple hosts, you can call Promise Technical Support at 1 (408) 228-1500. Our VTrak line is open 24x7.
