Troubleshooting An Optical Drive - Dell PowerEdge R930 Owner's Manual

Steps
1 Enter System Setup, and ensure that the Internal SD Card Port is enabled.
2 Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
3 Remove the system cover.
NOTE: When an SD card failure occurs, the internal dual SD module controller notifies the system. On the next restart, the
system displayed a message indicating the failure. If redundancy is enabled at the time of SD card failure, a critical alert will
be logged and chassis health will degrade.
4 Replace the failed SD card with a new SD card.
5 Install the system cover.
6 Reconnect the system to its electrical outlet and turn on the system, including any attached peripherals.
7 Enter System Setup, and ensure that the Internal SD Card Port and Internal SD Card Redundancy modes are set to the needed
modes.
Verify that the correct SD slot is set as Primary SD Card.
8 Check if the SD card is functioning properly.
9 If the Internal SD Card Redundancy option is set to Enabled at the time of the SD card failure, the system prompts you to perform a
rebuild.
NOTE: The rebuild is always sourced from the primary SD card to the secondary SD card.
