6. 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.
7. 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.
8. 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.
9. 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 X server cannot detect
the controller and thus displays the message "Find no RAID card." To resolve this, disable
UAC and run RAIDGuard X server as "administrator".
Vista:
a. Control Panel -> User accounts -> Change security settings -> Deselect "Use User
Account Control (UAC) to help protect your computer."
b. Restart the computer to turn off UAC.
Windows 7:
a. Type "MsConfig" in Start Search to start System Configuration. Then go to Tools tab,
select Change UAC settings, then click on Launch button.
b. Slide the slider bar to the lowest value (towards Never Notify) with the description
showing "Never notify me".
c. Restart the computer to turn off UAC.
