Situations requiring the assistance of a service representative

Report server problems that require technical assistance from the Technical Support Center.

Some troubleshooting tasks on the server require the assistance of a customer support representative. These tasks are not common and are only performed if the support representative deems it necessary.

To prevent loss of data and damage to hardware and to find a proper solution, contact your support representative before attempting any of the following tasks.

If you have to perform any of these tasks on your server, immediately contact the iSeries™ and AS/400^® Technical Support Center for further assistance.

• Perform main storage dumps on servers with logical partitions
  When the server has a failure, it may create a main storage dump. A main storage dump copies the contents of the server's memory to disk. It is an important tool for problem analysis. On a server with logical partitions, there are two types of failures that may cause main storage dumps: server failure and secondary partition failure.
• Forcing a main storage dump on servers with logical partitions
