Problems setting up
Newly installed memory fails during Self-Test or is not detected.
Possible Cause:
The Memory DDR DIMM module may not be properly seated or may not be
supported by RAID SYSTEM.
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. RAID SYSTEM supports
184-pin DDR DIMM SDRAM.
Unable to access RAID SYSTEM after the operating system boots up.
Possible Cause:
RAID SYSTEM is not configured.
Fix: Make sure RAID SYSTEM is configured for a RAID level. If no RAID level is configured the
operating system will not detect RAID SYSTEM 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 new RAID arrays.
Fix:
Reconfigure the array from the RAID params 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, RAID SYSTEM will halt requests from the host (see
above).
Fix: Make sure the Write Buffer option of the RAID Params 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.
