Hello,   The configuration information, logs, etc are stored as part of the RAIDset.  When the CM boots from the SD, it loads the OS for the controller.  The controller goes out and looks for available drives.  Then scans each drive for a RAID label.  Using that information it enables the RAIDset.  Then it mounts a partition from that RAIDset to continue the boot process.   This is analogous to Linux LVM.  The drives have a physical label, then meta data is loaded to bring the Volume Group Online, then any  Logical Volumes are discovered.  Then the OS can mount them.  Same principle for Windows.  The BIOS detects the drive and starts the bootloader.  The boot loads sees the partition and loads the OS.    Regards,  Don 
We have a few M4110 EqualLogic storage systems in the M1000e dell enclosure. one of them is only operating on 1 controller (another slot is not working.) if the working card fails, we will have no cards in the system. if we get a replacement card and swap the SD card, what would need to be done so that the replacement card can recognize the array/raid again?  Any help will be greatly appreciated.
