Hi,
I am using Storage Foundation for windows HA, Now i wan to replace my old HP storage with new NetApp storage for this i mirrored the data of Exchange servers 2007. before removing the HP storage i just want to make sure the my mirrored data is consistent. Is there any tool or option in the SFWHA to check the data conssitency. I am also using VVR between two sites for teplication the DATA

Hi David,
I am a Consultant so I was just wandering if vxverify and vxrync are tools I can tell my customers they can use. If either or both of these tools output with JUST somehting like "Your mirror/replicated copy is out of sync" then this is likely to worry customers- i.e if these tools only compare all blocks and do not compare "used blocks", if the customer knew this and knew that by default only "used blocks" are synchronised, then they wouldn't be using tool as it is of no use, so if a customer is using this tool, then they probably don't know that by default only "used blocks" are synchronised and they are going to be worried if the tools reports the data is not in sync.
So I think latest version 6 should be tested to see if indeed an issue exists - perhaps this tools provides an output which shows used blocks.

Mike,
Thank you for the reply. I will be working on this in a 6.0 lab. I will notify you of my findings.

Mike,
I am still working on my lab however I see that the vxverify command is a simple out put of the offsets

So what does output show for a mirror that was created using defaults - i.e only used blocks are synced.
