When an unexpected system halt occurs, the system dump facility automatically copies selected kernel data areas to the dump device. These areas include kernel segment 0 as well as other areas registered in the Master Dump Table by kernel modules or kernel extensions. Dump data is saved either before the system reboot when the traditional system dump is configured or in parallel to system reboot when the firmware-assisted dump is configured.
Lists the current dump devices. A primary dump device handles system dumps. The secondary dump device is used if the dump to the primary device fails.
Note: You must have root user authority to display the current dump devices.

Displays an estimate of the size of the system dump if it were taken at this point in time.

Allows you to change where the dump will be copied when the system reboots. This also allows you to select whether or not the system will halt during reboot and prompt you if the dump cannot be copied.
Note: You must have root user authority to change these attributes .
You must give the directory full path name, and the directory must be in the root volume group. The default is the /var/adm/ras directory.
Note: You must have root user authority to change the directory.
If set to true and the dump cannot be copied, the boot will continue without copying the dump off the paging space. The default is no.
Note: You must have root user authority to change this value.
Initiates a system dump and writes the results to the primary dump device.
Note: You must have root user authority to start a system dump and write it to the primary dump device.
Initiates a system dump and writes the results to the primary dump device.
Note: You must have root user authority to start a system dump and write it to the primary dump device.
Initiates a traditional system dump and writes the results to the secondary dump device. Firmware-assisted dumps are not currently supported for the secondary dump device.
Note: YYou must have root user authority to start a system dump and write it to the secondary dump device.

Copies an existing system dump to a file designated by the user.
Note: You must have root user authority to copy a system dump to a file.
Copies an existing system dump to a formatted diskette. Depending upon the size of the dump, additional diskettes may be necessary.
Note: You must have root user authority to copy a system dump to a file.
Set this item to true or false. If this item is set to true, the Ctrl-Alt 1 (Numpad1) and Ctrl-Alt 2 (Numpad2) key sequences start a dump, even when the key switch is in the Normal position or when no key switch is present. The Reset button also starts a dump when this item is set to true. A dump is never started when the key switch is in the Secure position.
Enables the system to check the dump resources periodically to ensure that the dump device and copy directory can receive the system dump. The default is "Yes".
The time at which the dump check is run. The default is for cron to run the dump check at 3:00 p.m. local time each day. For maximum effectiveness, run the dump check when the system is most heavily loaded so that the system dump is at its maximum size.
Indicates whether to mail dump check results to the root user or to log the results in the error log. The default is "log".
Enables the system to detect rapidly logged duplicate errors in the error log. The default is "on".
The approximate time interval, in milliseconds, within which an error is considered to be a duplicate if it is identical to the previous error. Duplicate errors that occur after this time interval are not considered to be duplicates even if they are identical to the previous error. The allowed value range is from 1 to 2147483647. The default time interval is 100, or one-tenth of a second.
The maximum number of duplicate errors the kernel is allowed to accumulate before a duplicate error is forced out and it is logged as a new error. The allowed value range is 1 to 2147483647. The default is 1000.
Reports only errors that are duplicates of previous errors generated by the error log device driver and which occurred within the specified time interval. The default is "no".
Consolidates the detailed duplicate error report by logging the duplicate error number and only the first and last times the error was logged. The default is "no".
Indicates whether to compress the next generated dump.
Specifies the level of detail in the report. The detailed error report provides comprehensive information, including error identifier, class, type, description, probable causes, and recommended solutions. A summary contains descriptions of errors by identifier, type, class, and resource name. An intermediate error report provides a shorter version of the detailed report. The choices are:
Specifies the type of dump to perform between traditional and firmware-assisted system dump.
Note: You must have root user authority to modify the type of dump.When "traditional" is specified, the dump data is saved before system reboot (traditional system dump). When "fw-assisted" is specified, the dump data is saved in parallel with the system reboot (firmware-assisted system dump). The fw-assisted setting is only effective after a system reboot.
Note: You must have root user authority to modify the type of dump.
This option is only relevant to firmware-assisted system dump. It specifies if the full memory dump is disallowed, allowed or required.
Note: You must have root user authority to modify the full memory mode of the dump.
This is only relevant to firmware-assisted system dump. When "disallow" is specified, the full memory dump is never taken. When "require" is specified, the full memory dump is allowed and always performed. When "allow" is specified, the full memory dump mode is allowed, but performed only when the operating system cannot properly handle the dump request.
Note: You must have root user authority to modify the full memory mode of the dump.
Initiates a system dump according to the current configuration and writes the results to the primary dump device.
Note: You must have root user authority to start a system dump and write it to the primary dump device.
Starts a full memory system dump to the primary dump device independently of the current configuration.
Note: You must have root user authority to start a system dump and write it to the primary dump device.
Starts a selective memory system dump to the primary dump device independently of the current configuration.
Note: You must have root user authority to start a system dump and write it to the primary dump device.
Forces a traditional system dump to the primary dump device independently of the current configuration.
Note: You must have root user authority to start a system dump and write it to the primary dump device.
