I have a Dell T610 server with the onboard H200 RAID controller and running Windows SBS 2008. The system presently has a single drive and I would like to add an identical drive and mirror it with RAID 1. I would like to do this without losing the data on the existing drive.
I tried this before using the Dell Management console in Windows, but it erased the primary drive.
I am hoping that if I do this from the utility one accesses before booting Windows it will mirror without wiping the primary drive. Does anyone have experience with this who can confirm whether or not it will erase the drive?
If I can't get a definitive answer, I'll just try the mirroring with some drives that don't matter and see if the primary one gets erased. If it does, the only option I see is:
1) Make a good backup of the drive using Windows Server Backup
2) Test the backup by restoring to another drive to confirm that it works
3) Create the mirror
4) Restore to the mirror
Comments on the proposed procedure would also be welcome.
