to indicate that the hard reset has been initiated. A hard reset erases the
current configuration and restores the unit to the factory default settings.
See 39XX/51XX Product Fundamentals for more information about the
factory default settings.
Note: If the reset button is pressed when the system is unresponsive, an
additional logging behavior will be triggered. See “Creating a State Dump
or Core Dump Log File” on page 9-2 for more information.
Note: Pressing the reset button will also result in an LED indication. The
LED behavior is described in “LED Overview” on page 5-1.
Creating a State Dump or Core Dump Log File
Two types of log files are available:
• State dump log — The state dump provides a summary of the current and
previous state of the system.
• Core dump log — The core dump provides a summary of the processes
that were running when the system became unresponsive.
The creation of these files is triggered by depressing the reset button (for
either a quick or hard reset) on 5160 systems.
The log file creation varies depending on the state of the system when the
reset button is depressed. One of the following scenarios will occur:
• System was responsive when the reset button was depressed — The
state dump file is generated before the system reboots. There will be
minimal delay (approximately 5 seconds) while the state dump file is
created and stored to the system memory. After the state dump file is
created the system will reboot.
• System was unresponsive when the reset button was depressed —
In this case a full core dump will be initiated, and then a state dump. There
will be a delay (up to 2 minutes) while the core dump file is created and
stored to system memory. Next the state dump file is created and stored
to system memory. After the both the core dump and state dump files are
created the system will reboot.
When the system reboots, you will be able to retrieve the state dump file and
core dump file (if it exists) from the system. The log files are stored in the
following locations:
• State dump log files: /mnt/sysfs/log/push_button_state-dump
Note: If a state dump file already exists on the system, it will be renamed
push_button_state-dump.prev when the new file is created.
• Core dump log files: /tmp/corefiles/
These files can be used to assist with troubleshooting the system.
