Driver Events
The reporting of driver events is controlled by the
event mask driver setting. See the Driver Settings
section for information on how to set this mask. The
hexadecimal mask value is the sum of the event type
values for the events you would like to see.
The ATTO driver uses the system log to communicate
driver events to the user. Each event begins with a
driver and channel identifier,
ATTOExpressSASRAID2 X.Y.Z
(ATTOExpressSASHBA2 X.Y.Z for H6xx
products), where X is the PCI bus number, Y is the
PCI device number and Z is the PCI function
number.In general, only errors that are output for
event type 'Fatal' are significant; all others are mostly
for informational or diagnostic purposes. When
turning on event logging, be aware that certain events
reported as errors are expected. For example, a SCSI
Check Condition error will be reported for the first
command sent to a device after power on or a reset
condition. Also, certain data underrun errors are
expected by the software and are normal.
