We recommend Event Logging only be active for troubleshooting purposes as
performance will be affected and that when in this mode of operation, all flags be
enabled.
To enable the advanced event logging features of the ATTO U320 Dual Channel
SCSI Host Adapter in a
MAC
environment, please do the following:
Open a Terminal window.
At the prompt, enter the following command:
sudo nvram atto-args-u320="0xffffffff" (note: there are eight f’s)
If you are not the root user, you will be prompted
for an administrator password.
Reboot the system for the changes to take effect.
Advanced event logging is now enabled. To retrieve the log to provide to support
personnel please save the terminal output or use standard redirection when
starting ATTOExpressPCI4Log to save the output to a file.
