Product Activity Log (P AL) The P AL is the general use system log containing entries for informational events, thresholding incidents, dumps, and err ors that need to trigger service actions. The entries are full of basic and detailed information on the event in a somewhat raw form.
v W ork with service action log The SAL is a utility that scans the P AL and displays entries that requir e service repr esentative action. It pulls out the relevant information fr om those entries an.
The Licensed Internal Code maintains a 128KB shadow log on the load-source disk. The log contains a duplicate copy of the latest entries. When you perform an IPL to Dedicated Service T ools (DST), the Product activity log option uses this shadow log. Note: The shadow log is not available in the stand-alone environment (T ype-D IPL).

Return to the procedur e that sent you here, if one. This ends the procedure. For information on interpreting the hexadecimal r eport, see “ Hexadecimal report ” on page 1 15.
Interpreting Product Activity Log reports The data in the product activity log wraps. The newest log entries overlay the older ones. There is not an option to delete or clear data, but you can r educe the log sizes so that they wrap more quickly . Figure 48 is an example of a printed product activity log r eport.
Resource name The Name or Resource name field contains a description of the r esource that is associated with the entry . The system assigns a resour ce name, but that name might be changed to a new value by the customer . Depending on the data, the following priority scheme is used for the name field: 1.
For more information on r esource names, see “ Resour ce names ” on page 242. Resource type, model, and location The T ype , Model , and Physical location fields pr ovide entry information that can assist in problem analysis. The Physical location field contains the location of the resour ce that is most closely related to the entry .
Hardware redundancy lost An error occurr ed in redundant (back-up or duplicate) har dware. This function continues to operate, but service is requir ed. A second failure in this hardwar e results in a loss of the function. Informational Indicates that an event of importance occurred that was not an err or .
Multiple SRC entries System Licensed Internal Code entries might appear more than once for a single problem. This occurs when the original system r eference code is permanent or temporary and additional data is logged at the same time. The additional data can be informational, temporary , an IOP dump, or any other classification.
Note: Use the physical address information to locate a device or car d that is within the system unit. Sequence number The sequence number increases by two each time an entry is placed in the log. Secondary code The secondary code is a 4-byte hexadecimal value that provides additional detailed entry information.
