This error occurs when 2nd SD card is installed. The error points to a faulty SD card; but could be caused by implementation or configuration errors.

Installing SD cards:

Even though the servers come with 3 SD card slots, the one in the rear is for the iDrac vFlash Feature. The other 2 slots are for the Standalone SD cards.

If the case is non-redundant, SD1 is the master even if SD2 is populated.

You may be prompted to rebuild the SD card if it has been replaced so go ahead and initiate this by selecting “yes”. If the error continues, set server to factory defaults and then configure Bios.
