another. If there are pre-existing zones setup, be sure to add the

Errors are reported while trying to flash new firmware onto the SAS controller.
The ATTO Configuration Tool performs validations on the structure of the file. If
it does not pass these validations, the file is rejected. The image file may be
corrupted. Try downloading the image file from the support section of the
website again.
If this still does not work, check to see if there is a newer version ATTO
Configuration Tool and driver. If so, make these updates first then try flashing the
controller.
The SAS controller fails its Power On Self Test.
The BIOS driver will perform several checks to verify that the controller is
functioning. If the BIOS driver determines that the adapter has non-functioning
hardware it will not complete the initialization of the OS driver. If the BIOS driver
determines that the firmware on the adapter is not functioning, then it will
complete the initialization in degraded mode. Under Windows, degraded mode
will not perform I/O but it will allow the end user to flash the adapter with working
firmware. The POST failure will be recorded in the Windows Event Log. Try to
re-flash the firmware using the Configuration Tool in Windows. If the problem
persists, replace the controller.
The software application being used to communicate with the attached
SAS/SATA devices reports Parity or communication errors.
Check your cables. There could be slight damage to one conductor causing
intermittent failures.
Check drive status in the ATTO Configuration Tool to make sure no drives have
faulted.
Check for new drivers and firmware. There may be an incompatibility between
the Intel chip and certain hardware. There are fixes with each new driver and
firmware release.
If the issue is not resolved, enable the Event logs as described below and
contact ATTO Technical Support.
