Maintenance Object Repair Procedures

c. Error Type 67 is logged when the Shadow Link Test (#318) fails. This
implies that the shadowing mechanism is not functioning.
The functionality of the Memory Shadowing Link should be checked by
issuing the test shadow-link command. If the test passes, the memory
shadowing mechanism may be functional. However, to restore the memory
shadowing, look for the presence of Error Types 82, 85, and 106 and use
the recommended commands to clear these errors.
d. Error Type 80 is logged when the Active SPE Maintenance/Tape Processor
reports that the handshake that is maintained between the processor and
the Duplication Interface circuit pack in the A carrier has been lost. This
implies an inability to communicate with the Standby SPE.
The status of the handshakes should be checked by issuing the test
duplication-interface a and the test duplication-interface b commands.
These commands initiate background tests that verify whether the
handshake between Dupint-A and Active-MTP is operational.
If the handshake between Dupint-A and Active-MTP is operational, the
communication path between the Active SPE and the Standby SPE may
be functional. However, to restore the communication path, look for the
presence of Error Types 58, 81, 82, 98, 99, and 106 and use the
recommended commands to clear these errors.
e. Error Type 81 is logged when the Duplication Interface circuit pack in the A
carrier reports that the handshake that is maintained between the circuit
pack and the Maintenance/Tape Processor on the Standby SPE has been
lost. This implies an inability to communicate with the Standby SPE.
The status of the handshakes should be checked by issuing the test
duplication-interface a and the test duplication-interface b commands.
These commands initiate background tests that verify whether the
handshake between Dupint-A and Standby-MTP is operational.
If the handshake between Dupint-A and Standby-MTP is operational, the
communication path between the Active SPE and the Standby SPE may
be functional. However, to restore the communication path, look for the
presence of Error Types 58, 80, 82, 98, 99, and 106 and use the
recommended commands to clear these errors.
f. Error Type 82 is logged when the Duplication Interface circuit pack in the A
carrier reports that the handshake that is maintained between the circuit
pack and the Duplication Interface circuit pack in carrier B has been lost.
This implies that the shadowing mechanism is not functioning.
