StorageWorks Storage Mirroring problem with Windows Server 2003 Domain Controllers.

Hi there

Recently I have start working/testing with HP StorageWorks Storage Mirroring. The objective of these tests is that I can succesfully mirror my servers, automated.
Though I have stumbled onto the following problem:
Whenever I try to mirror a server that is a domaincontroller, the server gets mirrored but I get the following error everytime I boot: http://i44.tinypic.com/2hq8ppu.png
Windows advises me to reboot into Directory Services Restore Mode, whenever I do so, and check the event log, I get the following message (split in two images)
http://i41.tinypic.com/2v3t3px.jpg (Upper part)
http://i42.tinypic.com/14si554.jpg (Lower part)
So it seems the Active Directory didn't get copied/mirrored completely or succesfully.
When I try to do the same with servers that are not domain controllers, everything works out just fine without any errors, and a complete copy was made. Though not with domaincontrollers. But I have found a solution. When I reboot into the last known good configuration it allows me to boot the last known good configuration of the mirrored server, wich is good. Though I'd like an automated solution, that does not require manual interaction. So either a solution for my problem, or a way that I can automatically reboot into the last know good configuration (if that is even possible?).

Thank you for your time and hopefully I can get an answer.

Oh yes, I'm using a Full-Server failover. And the problem occurs when the failover is complete.

why do you want to mirror a dc ??
pls do not mirror or clone a dc !
you will get inconstistency of the dc database and ran into various following Problems.
I think you should check your Domainconception with MS Best Praktices.
maybe you should try this

Well, HP StorageWorks should work for it aswel. Because the DC can also failover, and then you don't have anything.
