SHDW-LNK (Memory Shadowing Link)
Issue 4 May 2002
10-1499555-233-123
Active SPE’s value. Thus, the test is not as comprehensive in terms
of testing the memory aspect of shadowing as is the 80286 method.
The reason for this is the inability to shadow flash memory.
Management Terminal Message Line Errors
In addition to Shadow Link Test (#318) Error Codes, the following message line
errors may be displayed when attempting to run this test. They are:
■ “Standby SPE not available; for information use status system”
This message line error corresponds to Error Code 2020. It is displayed if
the Shadow Link Test is attempted within the first five minutes of a restart of
the Active SPE (that is, prior to the Active SPE holding the Standby SPE
reset and refreshing it).
■ “Standby SPE busy with another task; for information use status system”
This message line error corresponds to Error Code 2018. It is displayed if
the Shadow Link Test is attempted while the Active SPE is performing
some Maintenance Mode activity on the Standby SPE other than system
technician-demanded maintenance.
■ “Cannot interrupt Standby SPE while entering maintenance mode; please
try later”
This message line error is displayed when test shadow-link has been
issued and subsequently canceled and then refresh spe-standby is
issued while maintenance software is in the process of performing the
Shadow Link Test. Allow up to three minutes for the Shadow Link Test to
complete before issuing the refresh spe-standby command again.
In either case, the following actions should be taken:
1. Issue the refresh spe-standby command to put the Standby SPE in
Standby Mode. This command may have to be issued multiple times. If the
refresh spe-standby command successfully completes 5 times without
the Standby SPE becoming labeled “standby” on the status system form,
wait 20 minutes. This does not include cases where the command
completes with the terminal message line errors “Refresh not successful;
use ‘display errors’ to check for STBY-SPE errors” or “Cannot interrupt
Standby SPE while entering maintenance mode; please try later.” Issue the
refresh spe-standby command once more.
2. Repeat the command.
3. Issue the test spe-standby long command.
