DUPINT or DUP-CHL Alarms
As long as any alarms against either of these MOs persist, memory shadowing
will not be turned on.
Standby PKT-INT Major Alarms
These prevent memory shadowing. See “PKT-INT”. It may be necessary to reset
the board (
reset packet-interface
).
Standby MEM-BD Major Alarms
These prevent memory shadowing. See “MEM-BD”.
When you observe any of the above problems, first busyout the standby SPE,
then fix the given problem (usually with a lock-and-power-down replacement),
then release the standby SPE.
If any of the above problems persist, or if none of them appears but shadowing
remains off in the presence of good handshake, escalate the problem.
Resolving Refresh Problems
It can happen that handshake communication and memory shadowing can both
be maintained to a standby SPE, but for some reason that SPE cannot be
completely refreshed. In this case, one must distinguish between delays in
refresh completion and outright failure. This section addresses the situation in
which shadowing remains on, handshake remains up, but refresh will not
complete.
Delays in Refresh
Under extremely heavy occupancy loads, standby refresh can be delayed but it
is still expected to complete within 10 minutes of the time when memory
shadowing was turned on. You should not see delays greater than this without
some STBY-SPE alarm.
Failure of Refresh
The refresh operation occurs in two steps:
■ Refresh of Packet Interface dual port RAM (very quick execution)
■ Refresh of all memory on all memory boards
A failure can occur in either of these steps. When refresh fails, STBY-SPE error
code 1281 is logged. The auxiliary data indicates which aspect of refresh failed.
Aux code 1383 indicates that the memory board part has failed. This typically
indicates a problem with
active
SPE memory circuit packs. Execute the long test
sequence against both active SPE memory circuit packs and see “MEM-BD”. If
