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 steady 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?
A: Please check the LED indicators on the B08S2-PS front panel against the appropriate user
documentation for your particular storage system. Follow the instructions to launch RAIDGuard X to
obtain Event Log information for further analysis.
