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.
6. 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.
7. 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.
8. 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.
9. Q: My RAID system has an actual capacity of more than 2 TB, but in Windows XP and
Windows 2000, it will only do a full format of less than 2 TB in capacity. How can this
be resolved?
A: Since Windows XP 32 bit and Windows 2000 does not support GPT, both can only
continue to use MBR (Master Boot Record), which only supports up to 2TB in one
volume. To see more than 2TB in a single volume in Windows XP or 2000, go to
RAIDGuard X, select "Create Array" and set the sector size to 4096 bytes. By doing
this, Windows XP and 2000 will be able to format an MBR volume greater than 2TB.
However, if the sector size is set to 4096 bytes, it can lower the performance of the
RAID.
10. Q: In Windows Vista and Windows 7, after having confirmed that the files on the
installation CD have been completely installed, why does it still show "Find no RAID
card"?
A: Windows Vista and Windows 7 has a built-in ability to automatically reduce the
potential of security breaches in the system. It does that by automatically enabling
a feature called User Account Control (UAC). When UAC is enabled, the RAIDGuard
