I recently removed some smaller drives from my server, after moving all files from them, slowly replacing them with larger drives. I now am having big problems. Disk 1 is new and has no data on it, Disk 2 and 5 are not currently populated as I am going to put the larger drives in those locations. I hope all my data on those drives are not lost, how do I get Unraid to recoginze the other drives without formatting so I preserve the data?

Problems on 12/13

• Plex did not have any of my media

• I tried to restart the container, it would not start with just a "server execution error"

• I then stopped the array, tried to restart it, it would not start with a "unraid Buffer I/O error on dev" for each drive.  

• I restarted the server, it said that one of the drives was the wrong drive, when I it, it started a rebuild of that drive

• Plex still did not have any of my files

• I restarted the container, it did restart but still no files

• I then edited the container, did not change anything, just checked the paths, my files are back but it had to completely rebuild all the metadata

• I stopped the array and tried to set disk 1 to no device, it would not change and I could not start the array again

• I restarted the server and the only array device that is recognized is disk 4

• I did a new config and selected preserve current assignments, it did not help,

  • I still cannot see disk 1, 3, 6, 7 or the old smaller drives that I have removed from the array slots but are still physically hooked up

Disks are not being detected. This is not a software issue; check connections, and also check to see if they are detected in the BIOS

It looks like my SAS card overheated and burned up. I had another one but it needed re-configured as non of the drives were showing. I spent ALOT of time trying to figure this out so I thought I would post my fix here. This is specifically for the SAS 9206-16e Dual SAS 2308 HBA but can be modified with whatever, flashing utility, firmware, and bios for your Broadcom card.

1. Download the following 

   1. https://www.broadcom.com/support/download-search

      1. Download the Installer for linux

         1. My Flashing Utility- sas2flash

      2. Download the MSDOS firmware package

         1. My Firmware- 9206-16e.bin

         2. My Bios- mptsas2.rom

   2. https://github.com/thomaslovell/LSIUtil/tree/master/Binaries/LSIutil_1.70_release_binaries/linux

      1. LSI Utility- lsiutil.x86_64

2. Save the files listed to the boot drive under a new folder named lsi

3. Open up a terminal window and enter the following

   1. mkdir /lsi

   2. cp /boot/lsi/* /lsi

   3. cd /lsi

   4. chmod +x sas2flash

   5. chmod +x  lsiutil.x86_64

   6. ./sas2flash -o -f  9206-16e.bin -b mptsas2.rom

   7. ./sas2flash -c 1 -o -f  9206-16e.bin -b mptsas2.rom

   8. ./lsiutil.x86_64

   9. Select Chip 1

   10. Option 61

   11. Option 99

   12. Exit Chip 1

   13. Select Chip 2
