TAPE Subsystem Exception Report

This part of the exception report series provides the primary listing of events to determine if the TAPE subsystem has excessive errors or is operating within acceptable limits.

This report provides the information to connect these events to the other reports in the series that have more details.

Examples of these reports are listed as follows.

If the record is a MIM, the information appearing in this column will be the volid. If the record is any other type, the device type will appear in this column.

2

This field shows the unit most likely to be the source of the failure, even if the failure is recorded against another unit. EREP identifies the PFU based on the failure affect and the units reporting errors.

PFU	DESCRIPTION
MEDIA	Media (tape volume)
DEVICE	Device involved (3590)
CONTROLLER	Controller (drive string controller, or something common to more than one device on the string)
LIBRARY	Tape library

3

This field defines the function or machine area affected by the failure.

4

The EREP-assigned CPU identifier. If there is more than one CPU, one is shown and a plus sign is printed to indicate that there is more than one.

5

Use the physical address to locate information on other EREP reports. EREP uses the primary channel and unit address (PCUA) or device number if the devices do not provide physical IDs.

6

This field contains the error totals under the error types shown in the following table:

TYPE	DESCRIPTION
SIMS	The count of SIM messages reported by the unit and totaled for the PFU within the given failure.
MIMS	The count of MIM messages reported by the unit and totaled for the PFU within the given failure.
PERM	The count of permanent errors recorded against the unit and totaled for the PFU within the given failure affect. (A permanent error is indicated by a zero temporary error bit in the OBR record.)
TEMP	The count of temporary errors recorded against the unit and totaled for the PFU within the given failure affect.
