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: 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.
4. 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.
5. Q: If "Find no RAID card" appears in a Windows host server, how can this be
resolved?
A: Please make sure the PCIe cable is properly connected to the back of the host
server and the RAID system. Check the Device Manager in Windows to confirm that
the correct driver has been installed for the HBA. If both conditions have been
verified and the problem persists, please use the "Manually Add Controller" option.
6. Q: On a MAC host, after entering the GUI and adding a controller, there is no device
listed. How can this be resolved?
A: Please first confirm whether the hardware environment of the RAID system is
functional. Also, ensure that the system drivers have been correctly installed. Next,
go to "Utilities > System Information> Software > Extensions" and check whether
Accusys6xxxx is listed. In order to confirm whether GUI Server Service is running on
the system, Go to "Utilities > Activity Monitor" and check whether the program
name DTRGuiSrv01 is under the program column. If the situation persists, please verify
again that the hardware environment is not the source of the problem and reinstall
using the MAC installer.
