Performing dumps
Learn more about the different types of dumps that can be performed
and how to manage them, including copying, reporting, and deleting them.
Dumps can occur automatically after a failure or external reset,
or after a manual request. The dump information provides valuable information
on system status and should be reported to your next level of support or your
hardware service provider.
- Platform system dump: A platform system dump is a collection of
data from server hardware and firmware, either after a system failure or a
manual request.
- Service processor dump: A service processor dump is a collection
of data from a service processor either after a failure, external reset, or
manual request.
- i5/OS® main
storage dump (MSD): A main storage dump is a collection
of data from the i5/OS's
main storage. It can be manually initiated when the system administrator suspects
a system wait or loop, or automatically by the server firmware as the result
of a system failure.
In addition, there are other dumps that generate automatically.
These include:
- Platform event log entry dumps (which are generated by server firmware
when a platform event log entry is truncated)
- Resource dumps
- SMP dumps
- Performing a platform system or service processor dump
A platform system dump or service processor dump is performed when your next level of support or your service provider suspects a wait or loop in the server firmware.
- Performing an IBM i5/OS main storage dump
