I have a bit of a problem with a DL385 server using two P600s and would like
some advice. The initial installation was done in error putting the boot device on an internal P600 SAS RAID controller in slot 3. Later on another P600 was added in slot 1 that connects to an external array on an MSA50. A mirror of the boot device was made to the MSA 50. Unfortunately, this configuration has some poisonous errors: A) The secondary mirror - because it is on the slot 1 controller - is showing up as Disk 0 on the system. I would like to be able to break off this mirror and save it for an emergency, but when I break the mirror, it is my primary that is is breaking not the backup. B) If we attempt to boot the system off of the backup mirror on the MSA50, it refuses to boot. It might be some disk geometry issue. This leads to my questions: 1) Can anyone suggest a method for breaking a mirror in Windows 2003 that lets me specify which of the two mirrored volumes will remain with the original drive letter? You are able to choose to some degree when you remove a mirror, but not when you break a mirror, which was a huge oversight by Microsoft in designing the UI to break a mirror. 2) If we remove the P600 from slot 1, boot the system to let the OS patch up the references to that controller, then power off and move the controller from slot 3 to slot 1, is the P600 going to retain all information about the arrays on that controller, and still be able to boot from it? I have had P600s lose all of their configuration information in similar kinds of situations, and I have gotten poor support from HP India and had data loss. So I'm very sensitive about the safest way to do this. -- Will |

Hi!
At this point, I strongly feel that the safest thing you can do is to back up all of your data and verify that the backups are good. Once you've done that, clear off the disks, and arrange both disks and controller hardware in the correct way. Then get the system back up and restore your backups. I don't think you can accomplish this any other way, especially if the hardware isn't currently installed in the right way. William |

Your solution just avoids the problem rather than understanding the cause. -- W |
