firmware using the Configuration Tool in Windows. If the problem persists,
replace the host adapter.
The software application being used to communicate with the attached Fibre
devices reports Parity or communication errors.
Check your cables. There could be a kink or a cut in the cable. Also, make sure
the ends of the fibre cables are clean. Dirt, such as fingerprints, can obstruct the
fibre link and cause communication problems.
Check the Fibre devices to see what type of connection mode and data rate they
are set to. Some devices use "auto" for these settings. Manually setting the
speed (1gig, 2gig, 4gig) may allow for better communication between the
devices. You may also want to force these settings on the card. This can be done
by using the ATTO Configuration Tool or entering into the ATTO CelerityFC
Utility.
If the issue is not resolved, enable the Event logs as described below and
contact ATTO Technical Support.
Errors are reported while using the ATTO Configuration Tool.
Note: Sometimes when using the ATTO Configuration Tool, an error message
describing an unexpected event or incorrect information discovered by the
application will be displayed.
Use the help text presented with the error message to correct the issue.
The following conditions cause a warning or error message to be posted in the
"Status" area of the configuration utility. These messages will be shown in red.
o An error occurred loading NVRAM data - The first time a host adapter
channel is highlighted, the application makes an attempt to read NVRAM
from the card. If the size of the NVRAM buffer does not match the expected
size, or if the NVRAM buffer couldn't be retrieved at all, this message is
displayed.
o Warning: NVRAM could not be read, defaults returned - This message occurs
as a result of corrupt NVRAM. When the driver accesses the NVRAM, a
continuity check is performed on the NVRAM to ensure the returned data is
valid. If this check fails, the driver has no other alternative than to return a
known NVRAM data buffer that represents card defaults. When this situation
occurs the defaults are presented via the graphical user interface and the
user is informed that the values shown are defaults. These defaults must be
committed in order to correct the state of the NVRAM.
o An error occurred updating the NVRAM - This message occurs during a
committal of NVRAM to the card. If the driver is unable to put the new
settings on the card, this message is displayed to the user and no changes
are made to the card.
o This is not a flash file, or it is corrupt – Checks are performed to assure the
proper file has been selected for flashing to the specific model of host
adapter.
