STBY-SPE (Standby SPE)
Issue 4 May 2002 10-1525 555-233-123
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 Dupint-B is operational. If the
handshake between Dupint-A and Dupint-B is operational, the memory
shadowing mechanism may be functional. However, to restore the memory
shadowing, look for the presence of Error Types 67, 85, and 106 and use
the recommended commands to clear these errors.
NOTE:
Because the handshake between Dupint-A and Dupint-B is tested in
the background, the test results from executing the test
duplication-interface a command do not indicate their current
status. However, if the background testing determines that all three
handshakes (that is, Dupint-A to Dupint-B, Dupint-A to Active-MTP,
and Dupint-A to Standby-MTP) have become operational, and if there
are no other current STBY-SPE errors, Error Types 80, 81, and 82
and the associated STBY-SPE alarm will be cleared in about 30
minutes.
g. Error Type 85 is logged when the Duplication Interface circuit pack detects
that writes made to the Standby SPE Memory are not being acknowledged.
This implies that the shadowing mechanism is not functioning.
The presence of time-outs when shadowing to the Standby SPE Memory
should be checked by issuing the test duplication-interface a long
command. This command runs a test that forces memory writes to the
Standby SPE Memory and detects time-outs waiting for acknowledgments.
If time-outs are not detected, memory shadowing may be functional.
However, to restore the functionality of memory shadowing, look for the
presence of Error Types 67, 82, and 106 and use the recommended
commands to clear these errors.
h. Error Type 98 is logged when the Active SPEMTP Dual Port RAM Test
(#104) fails. This implies an inability to communicate with the Active MTP.
The ability to communicate with the Active MTP should be checked by
issuing the test processor a | b short command, where “a | b” indicates
the carrier that contains the Active SPE.
i. Error Type 99 is logged when the Active SPE detects that the handshake
that is maintained between the Active SPE Processor and the Active SPE
Maintenance/Tape Processor has been lost. This implies an inability to
communicate with the Active MTP.
The ability to communicate with the Active MTP should be checked by
issuing the test processor a | b short command, where “a | b” indicates
the carrier that contains the Active SPE.
