Problems setting up
Newly installed memory fails during Self-Test or is not detected.
Possible Cause: The Memory SO-DIMM module may not be properly seated or may not be
supported by ACS-9910.
Fix: Re-sit the memory module in the socket and retry. If it continues to fail try moving it to the
other memory socket. Make sure the correct memory type is being installed. ACS-9910
supports 144-pin SO-DIMM SDRAM.
Unable to access ACS-9910 after the operating system boots up.
Possible Cause: ACS-9910 is not configured.
Fix: Make sure ACS-9910 is configured for a RAID level. If no RAID level is configured the
operating system will not detect ACS-9910 as a disk drive.
I try to set up an array using Quick Setup but fail. Why?
Possible Cause: If the error message Array1 Exists! appears, an array has already been
configured. Quick Setup can only be used to set up new arrays.
Fix: Reconfigure the array from the Edit Array submenu
Problems during operation
The front panel LCD displays alternating "Zz" characters.
Possible Cause: These characters are displayed when the cache is full with write request data
that have not been processed. Requests from the host are halted to flush the data in the
cache.
Fix: None needed.
The front panel LCD displays alternating "Ww" characters.
Possible Cause: These characters are displayed to indicate that write requests in the cache
are being processed. When these characters are displayed, ACS-9910 will halt requests from
the host (see above).
Fix: Make sure the Write Cache option of the Edit Array menu is enabled. In addition, more
cache memory may be required. By increasing the cache memory, the write buffer space
increases and will be able to handle the higher write requests.
Data loss for Windows 2000 during system shutdown
Possible Cause: RAID controller is a built-in host and some data is still in cache buffer during
system shutdown.
Fix 1: Set Cache Off
