I looked at the original specs and there was  an SD card and Internal Dual SD Module. 342-3595 : 1GB SD Card for RIPS 331-4441 : Internal Dual SD Module 318-2036 : vFlash SD Slot Filler   The folks on site took a look and the SD card was popped out or not seated. With the SD card pushed back in the BIOS now sees the SD card and boots from it.
Server would not power on. Dell tech came and replaced the backplane and PER620 card and then left. The server will now power on but will not boot the existing volume or virtual drive. The server is remote to us and I’m guessing and hoping it’s a simple configuration issue with the new controller but how did the Dell tech know if they didn't see it boot up?  The folks on site said the POST does recognize the 1 virtual drive.  But it does not boot up.  They tried to boot using the BIOS and the UEFI options. Is it something simple like setting the  virtual drive as bootable? I thought that some controllers could read the config from the disks? I was hoping there was maybe a tech note on getting the system to boot after replacing the back plane and or PER620 controller.
Dell R620 won't boot after PER620 replaced.
