Q Q & & A A
Q1:
When turning on the Windows host, “Find no RAID card” appears, how
can this be handled?
Ans: Please make sure the PCIe cable is properly connected to the back of
the host server and RAID system. In Windows, check “Device Manager”
to confirm that the correct driver has been installed for the Re-drive
card.
Q2: When turning on the MAC host, after entering the GUI and adding a
controller, there is no device listed. How can this be dealt with?
Ans: Please first confirm whether the hardware environment of the RAID
system is functional, and also make certain that the system drivers have
been correctly installed. Next, go to "Utilities > System Profiler >
Software > Extensions" and check whether the 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 after doing the above, please again double check that
the hardware environment is not the source of the problem, and reinstall
using Mac Installer.
Q3:
Why is it that 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 of capacity? How can this be resolved?
Ans: Since Windows XP 32 bit & Windows 2000 don’t support GPT, so they
can only continue to use MBR (Master Boot Record), and MBR only
supports up to 2 TB on one volume. To see more than 2 TB on 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
will be able to format an MBR volume to greater than 2 TB. However, if
sector size is set to 4096 bytes, it can lower the performance a bit.
