Yah Justin with Dell Support helped me get everything fixed. He thought it could have been from older firmware or possibly a disk issue in just the right spot. Here was the process. Went to my MDSM installation and got the csv files from the recovery folder. Just in case but I did not need them. Pull all drives and connections but management put in 2 new disks (slot0,1) that had not been in a MD3000i before and did not have any config database on them booted the primary card made sure it was successful then added the secondary card Once it was up and working on the 2 disks begin inserting the original slot 3-14 disks one by one validating that each one was detected and working. Then replace drive slot 0 with original and finally slot 1 At that point the software saw the original disk groups and we were able to do an import of my 2 groups Then updated to latest firmware on controllers and disks At that point we had to reconfigure iscsi connections and host groups Good to go.  My faith in the units has been restored. :emotion-2:  
Have 4 MD3000i units and they have been great for 5 years. Performing maintenance on switches and power at one of our racks. Have a 2 node cluster and MD3000i for our SQL. Powered down both SQL cluster nodes while recabling SAN switches. We did leave on the MD3000i chassis but I do not think this would cause a problem. Afterwards realized could not contact the management ports for the SAN.  This is not uncommon and typically a shutdown and restart does the trick.   In this case powered off the chassis, powered back on and both controllers just reboot before initiallizing the iSCSI port.  They ping but software cannot connect before they reset again. Used serial cable and watched the boot process, lists a Panic - unreconcilable ITA database before they reset.  Cannot find anything regarding an ITA Database. Tried using just one of either of the cards but no difference. Finally pulled the drives and it would boot fine but show no disk groups or anything. Even with one disk in the chassis it would go back to the problem.   Biggest issue is that we found out that the most recent backups of our SQL production was on another partition on this SAN. Really be a life saver if someone can point me at some more things to try or a guru.
