i’m still learning the ropes of the onboard sd cards in the r720. about a week or so ago, i was installing a pcie expansion card into an r720. the pcie expansion slots are located directly above the sd card slots. after i installed the expansion card i went about installing esxi. from the drac interface, i noticed that the sd card redundancy status was “Lost” and under removable flash media the sd card IDSDM SD2 was set to “Offline”.

i figured i might have dislodged one of the cards so i opened the server up again and reseated both sd cards. came back and checked, same thing. i went back once more and opened the server and this time instead of simply reseating the cards i swapped their places. i noticed that when i moved one particular sd card between the slots that an amber light lit up each time i seated the card. so even though the possibility of an sd card going bad is fairly slim…i started considering it.

i was just about to put a replacement request into dell when i noticed on the drac virtual console a message regarding sd card redundancy. all i had to do was confirm the request to restore redundancy and everything was back to normal.
