Troubleshooting an SD card
Prerequisites
NOTE:
Certain SD cards have a physical write-protect switch on the card. If the write-protect switch is turned on, the SD card
is not writable.
Steps
1
Enter System Setup, and ensure that the
Internal SD Card Port
is enabled.
2
Turn off the appliance, including any attached peripherals, and disconnect the appliance from the electrical outlet.
3
Remove the appliance cover.
NOTE:
When an SD card failure occurs, the internal dual SD module controller notifies the appliance. On the next
restart, the appliance 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 appliance cover.
6
Reconnect the appliance to its electrical outlet and turn on the appliance, 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 appliance prompts you to perform
a rebuild.
NOTE:
The rebuild is always sourced from the primary SD card to the secondary SD card.
