Considerations when interpreting product activity log reports

If you update an operating system release or apply a new operating system version to the system, the product activity log data might be cleared. (If you need the data in the product activity log, print it before you install the new operating system.)

Entries in the log might have been previously resolved (for example, machine check entries).

For more information on resource names, see Resource name.

If the system cannot display a character in any of the following fields, it displays an asterisk (*) instead of that character:
  • Resource
  • Type
  • Model
  • Serial number
  • Volume ID

You can use the Log Analysis report to analyze problems that occur over a period of time. Look for error patterns such as multiple I/O processor errors that occur at the same time, or errors caused by the environment that occur at the same time of the day or week. As you cycle through the different views of the Log Analysis Report screens, note that F11 shows variable text: Such as View Description, View Logical Address, View Physical Location, View Component Information, and View Resource Identification.
