Working 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 POWER5 platform system dumps, see Performing a platform or main storage dump.

A main storage dump can be performed in the following ways:

• Automatically - by the service processor as the result of a system failure.
• Manually - by using control panel functions when the system waits, loops, or appears to have an operating system failure.
