Tape Permanent⁄Recovered Error Summary

The tape permanent error summary report helps you analyze the causes of permanent errors. These errors require immediate attention because they indicate that something in the system needs to be fixed.

This report describes in more detail the permanent errors that appear on the tape subsystem exception report.

The following table shows how sense bytes 7 and 3 indicate the error type:

ERROR TYPE SENSE BYTE VALUES
Permanent Sense byte 7 will be 20 to indicate format 20 sense.
Sense byte 3 will be a value other than 48.
Recovered Sense byte 7 will be 20.
Sense byte 3 will always indicate 48. See note.
Service alert Sense byte 7 will be 20.
Sense byte 3 will always indicate 48. See note.
Note: This indicates that an error occurred and it took host interaction to recover from the error (CU error recovery was not adequate).

The errors are grouped under separate headings indicating classification of probable failures and are listed by CUA or VOLID (volume serial number) in the order they occurred.

Two groups of permanent errors are shown:
The following details are provided in the report:

The information is organized so that permanent errors are shown in the order in which they occur.

The long OBR format is used with tape drives.

The column headings may differ depending upon the specific device.

Figures containing examples of these reports are on the pages shown in the following table:

 1 
REPORT DATE, PERIOD FROM, PERIOD TO

REPORT DATE is the Julian date the report ran.

PERIOD FROM is the Julian date of the earliest record.

PERIOD TO is the Julian date of the latest record.

 2 
CHPID is the channel path ID (used in XA mode).
 3 
DEVNO/CUA is the device number in XA mode or the primary control unit address (PCUA).
 4 
CPU identifies the host processor reporting the exception. The actual CPU model and serial number are shown at the bottom of the report.
 5 
DTE is the Julian date from the OBR record.
 6 
TIME is the time from the OBR record.
 7 
VOLID is the volume serial number.
 8 
R/W/E/O defines the type of check as read, write, equipment, or other check.
 9 
CMD is the command code from the channel command word (CCW) in the OBR record.
 10 
SENSE BYTES is the sense data from the OBR record.

For sense byte definitions see the SENSE section of the maintenance information (MI) manual.

 11 
CU-ERR1 is the microcode-detected error code for the first error (control unit or drive), from the OBR record (sense bytes 10 and 11). This error code should not be used as an entry to the maintenance package unless efforts using CU-HW  14  and/or DR-ERR1  15  have not corrected the subsystem problem.
 12 
CU-ERR2 is the microcode-detected error code for the second error (control unit or drive), from the OBR record (sense bytes 12 and 13). This error code can be a result of the first error indicated in CU-HW  14 , DR-ERR1  15 , or CU-ERR1  11 .
 13 
CU-ERRL is the microcode-detected error code for the last error (control unit or drive), from the OBR record (sense bytes 14 and 15). This error code can be a result of the first error indicated in CU-HW  14 , DR-ERR1  15 , CU-ERR1  11 , DR-ERR2  16 , or CU-ERR2  12 .
 14 
CU-HW is the control unit hardware-detected error code from the OBR record (sense bytes 16 and 17). This error code defines a control unit failure and should be used to enter the maintenance package if you have multiple drive failures.
 15 
DR-ERR1 is the drive hardware-detected error code, from the OBR record (sense bytes 20 and 21). This error code defines the first failure for any drive and should be used to enter the maintenance package if you have single drive failures.
 16 
DR-ERR2 is the drive hardware-detected error code, from the OBR record (sense bytes 22 and 23). This error code defines the second or last failure for any drive and should not be used to enter the maintenance package if you have single drive failures. This error information provides supplemental information and may be a result of the first failure (DR-ERR1) in the drive.
 17 
CCW FLG is CCW bits 32 to 39 from the OBR.
 18 
SCSW/CSW is:
  • SCSW64—95 (in XA Mode)
  • CSW32—63

These are the SCSW or CSW bits from the OBR record.

 19 
CPU, MODEL, SERIAL NUMBER provides further information on the CPU listed  4  in the error summary lines of the report.
 20 
HDW-FSC is sense bytes 10 and 11. This is the error code for statistical analysis of temporary errors and will always be a B0nn type error code. This error code can be used for entry into the maintenance package.
 21 
STR-DEV is sense bytes 12 and 13. These sense bytes identify the drives within the string that are failing. See the FSI section table of contents for FSC B011 or B012 for a detailed explanation.
 22 
V/C-FSC is sense bytes 14 and 15. These sense bytes identify the types of unacceptable temporary errors. If sense byte 14 = B1, then sense byte 15 = the type of temporary errors that are unacceptable. See the FSI section table of contents a detailed explanation of B011 or B012.
