The scan log dump content can be set to the following:
1 = As Requested
The processor
2 = Optimum
The dump will include the smallest amount of information to diagnose a hardware error.
3 = Complete
The dump will include as much information as possible to allow the complete analysis of hardware and software errors.
4 = Minimum
The dump will include the smallest amount of information possible (a minimum number of hardware scan log rings).
The complete dump will take the longest time to finish; it may take as long as 1.5 hours on a fully configured system.
Option 3, Immediate Dump, can only be used when the system is in the standby state with power on. It is used to dump the system data after a checkstop or machine check occurs when the system firmware is running, or when the operating system is booting or running.
The scan log dump content can also be set from the Tasks menu in the AIX diagnostic service aids.
If a valid dump file already exists, the dump control code will stop because the contents of the prior dump must be protected.
