Deleting apartition that is part of a SteelEye DataKeeper mirror will yield unexpected results.• Using Disk Management to change the drive letter assigned to a partition that is a part of a SteelEyeDataKeeper mirror is not supported and will yield unexpected results.• The Windows Disk Management utility will take longer to start on the target node based on the numberof drives.
