Working with storage dumps
This information describes how to work with storage dumps.
A main storage dump (MSD) is a process of collecting data from the system's main storage. For more
information on main storage dumps, including platform system dumps, see Performing a platform or
main storage dump.
A main storage dump can be performed in the following ways:
v Automatically - by the service processor as the result of a system failure.
v Manually - by using control panel functions when the system waits, loops, or appears to have an
operating system failure.
Managing dumps
After you have performed a dump, or one occurs automatically, use this information to manage the
dump, including copying, reporting, and deleting it.
Dumps are deleted automatically when a new dump occurs, except for log dumps.
Performing dumps
Learn more about the 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 about system status and should be reported to your next level
of support or your hardware service provider.
v 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.
v 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.
In addition, other dumps, which are generated automatically, are:
v Platform event log entry dumps (which are generated by server firmware when a platform event log
entry is truncated)
v Resource dumps
v SMP dumps
Performing a platform system dump:
A platform system dump is performed when your next level of support or your service provider suspects
a wait or loop in the server firmware.
Only perform a platform system dump under the direction of your next level of support or your service
provider, after first providing to your next level of support or service provider a dump of the operating
system.
Note: Before performing a platform system dump, collect any reference code information from the
control panel or from the HMC.
