3490 FRU Summary Report

THE FRU summary report provides a summary of error codes logged and is listed by CUA. THE FRU codes can provide an entry into the maintenance information (MI) manual for both drive and control unit failures.

Figure 1 shows an example of the 3490 FRU summary report.

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

DEVNO/CUA is the device number in XA mode or the primary control unit address (PCUA).

3

CPU identifies the host processor reporting the exception and is shown as a value of A through H. The actual CPU model and serial number are shown at the bottom of the report. CHA identifies the channel adapter that was in use at the time of error. CU identifies the control unit containing the channel adapter. PTH identifies the control unit containing the buffer and data flow in use at the time of error.

4

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 8 and/or DR-ERR1 9 have not corrected the subsystem problem.

5

CU-F is a microcode-developed flag byte, from the OBR record (sense byte 9). This byte provides additional information, if available, for CU-ERR1 4 .

6

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 8 , DR-ERR1 9 or CU-ERR1 4 .

7

CU-ERRL is the microcode-detected error FRU 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 8 , DR-ERR1 9 , CU-ERR1 4 , DR-ERR2 11 , or CU-ERR2 6 .

8

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.

9

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.

11

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 can be a result of the first failure (DR-ERR1) in the drive.

12

OCCURRENCES is the total number of times this error code occurs.

13

DATE/TIME is the Julian date and time of the last occurrence.

14

CPU, MODEL, SERIAL NUMBER further identifies the CPU listed in the FRU SUMMARY REPORT.
