Duplication Interface Circuit Pack Invalid
Message Query Test (#272)
The Duplication Interface Circuit Pack Invalid Message Query Test sets the
threshold for the number of bad checksum errors the Duplication Interface circuit
pack detects before reporting the problem to maintenance and queries the
Duplication Interface circuit pack for the number of checksum errors detected.
The error threshold is set to 10. The query causes Duplication Interface circuit
pack firmware to clear its bad checksum error counter. This test is run on both
circuit packs, but has little meaning on Duplication Interface circuit pack B and
should always pass.

Result Description/Recommendation
1000 ABORT System resources required to run this test are not available.
2000 ABORT Response to the test request was not received within the
allowable time period.
2033 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5
times.
FAIL The Duplication Interface circuit pack is receiving an abnormal
number of corrupted messages.
1. First investigate other Duplication Interface circuit pack
tests that are not passing.
2. If this is the only test that fails, investigate and resolve all
alarms against PR-MAINT (Maintenance/Tape Processor).
3. Rerun the test. If the test still fails, follow the procedures
for replacing Common Control circuit packs and replace
the Duplication Interface circuit pack.
4. Rerun the test.
NO
BOARD
The Duplication Interface circuit pack has failed to handshake
with either the active Maintenance/Tape Processor (in the case
of Duplication Interface circuit pack A) or the Duplication
Interface circuit pack A (in the case of Duplication Interface
circuit pack B).
1. Refer to NO BOARD description for the Duplication
Interface Circuit Pack Status Query Test (#315).
PASS The Duplication Interface circuit pack has not received any bad
messages from either Maintenance/Tape Processor or the
other Duplication Interface circuit pack. All serial links are
operating fine.
