Performing a main storage dump

 

A main storage dump (MSD) is a process of collecting data from the system's main storage. It can be done in these ways.

• Automatically. By the service processor as the result of a system failure.

• Manually. By performing a function 22 on the control panel when the system waits, loops, or appears to have an operating system failure. You can perform this task by selecting option 22 from the Work with partition status display.

Choose the task that you want to perform:

• Perform an automatic main storage dump

• Perform a manual main storage dump

• Perform a manual main storage dump on a logical partition

• Copy a current main storage dump

• Report a main storage dump

• Delete a main storage dump

• Performing an automatic main storage dump
  After a failure that causes the system to perform a main storage dump (MSD), the Main Storage Dump Occurred display is shown

• Performing a manual main storage dump
  You can perform a manual main storage dump on a primary partition or a system without logical partitions.

• Performing a manual main storage dump on a logical partition
  To perform a manual main storage dump on a logical partition, follow this procedure.

• Copying a current main storage dump
  To copy a main storage dump (MSD) to a predefined storage area on the system, and to prevent an MSD from being overwritten when another dump occurs, complete these steps.

• Reporting a main storage dump
  If your system has the main storage dump auto copy enabled, your system might have automatically copied the current MSD to the auxiliary storage pool (ASP) using dump description Auto Copy, and then have the program initially loaded again on the system.

• Deleting a main storage dump
  When dump copies are no longer needed by your service representative, follow this procedure to delete them.
