NOTE: When an SD card failure occurs, the internal dual SD module controller notifies the
system. On the next restart, the system displays 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 the system on, including any attached
peripherals.
7. Enter the System Setup and ensure that the Internal SD Card Port and Internal SD Card Redundancy
mode is set to the required mode.
Verify that 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 will prompt you to perform a rebuild.
NOTE: The rebuild will always be sourced from the primary SD card to the secondary SD card.
Perform the rebuild of the SD card as necessary.
