If any of the tests fail, there could be a problem with the cabling. For example:
â–
If a cable is crossed (plugged into the incorrect port), then the NVMe drive DSN (Drive
Serial Number) test should report two drives where the DSN does not match. The cabling
for those drives should be inspected to ensure that it is correct.
â–
If multiple NVMe drive PCIe links are not active, or multiple NVMe drive DSNs are not
OK, then check the Port 2 connection on the NVMe switch card. If Port 2 is incorrectly
cabled, it could affect all three drives that are connected to that NVMe switch card.
7.
Once issues are resolved, power cycle the system by removing the power cords
from the power supplies, waiting 30 seconds, and then reattaching the power
cords.
8.
Retest the system by repeating Step 1 through Step 6.
Once all NVMe cable connection tests have passed, the server operating system can be booted.
