Note: - Trends reports do not report on SIM-producing devices such as
3990/3390 DASD.
- 9340 direct access storage subsystems are not shown in the trends
report.
- Within product groups, errors are presented by device address
or number or physical ID within generic device or product types.
- CPUs associated with records appear on the line with the device
address/number. Devices that provide physical IDs are associated with
the control unit and not with a CPU.
