Error log information
The Hitachi Gigabit Fibre Channel Adapter provides the functions to gather the failure
information (error log) when the various failures occurred.
Linux
Linux driver collects the various error log information using the daemon process (klogd)
which outputs the kernel messages. Accordingly, klogd and syslogd must be executed to
collect log information.
Though the output destination of log information is usually /var/log/messages, the output
destination can be changed depending on the klogd and syslogd settings. Confirm these
settings in advance.
All SLES's driver supports the script 'hfcrasinfo'. By executing the hfcrasinfo command,
you can collect syslog and other driver information at the same time.
