Appendix A: FAQs
1. Q: Why is my disk LED status RED?
A: This is likely caused by a faulty hard drive. Replace the faulty drive as soon as
possible to protect your data.
2. Q: After an array has been created in RAIDGuard X, but the host does not find the
array volume.
A: Please check the LUN Mapping to ensure the array volume has been corrected
mapped to a LUN. If this is not the case, try restarting the system and it will be
automatically recognized. Once LUN is assigned, you can perform formatting and
mounting.
3. Q: What does the eight LEDs on the Host Bus Adapter mean?
A: The eight LED indicate the connection status of the HBA (The LED closest to the
bracket does not light up.) If you have properly connected the HBA to the B08S2-PS
RAID controller, one set of 4 consecutive LEDs will be constantly lit. The second set of
4 consecutive LEDs indicates the type of PCIe connection - flashing LEDs indicate a
PCIe Gen1 connection, while solid LEDs indicate a PCIe Gen2 connection.
4. Q: Why doesn’t the performance reach the expected levels while testing the B08S2-
PS? Why isn't the performance steady enough?
A: If the performance is unsteady or not achieving the expected level, in many
cases, the HDD is the cause. Since the B08S2-PS is a highly efficient product, there is
extreme demand placed on each HDD. As a result, it is strongly recommended to
use the newest enterprise level HDD.
5. Q: Why is the B08S2-PS generating warning beeps?
