If your system stops without warning or disk errors occur, some object description information may not be updated correctly. If this happens, the object is considered damaged. When you perform an IPL, the system attempts to locate damaged objects and write them to the object recovery list. It writes a message (CPI18xx) to the history (QHST) log for each damaged object that it finds. If any damaged objects are added to the object recovery list during the IPL, message CPI8197 is sent to the QSYSOPR message queue.
Note: Some damage, such as damage to the contents of a database file, may not be detected until the object is used. If you suspect that a large number of objects on your system have been damaged, contact your service representative for advice on how to recover.
