Explanation
This message is issued when this end node has
attempted but failed to switch CP-CP sessions from its current network
node server to its preferred network node server. When it is issued
as part of a message group the first message in the group is IST1110I.
See the explanation of that message for a complete description of
the message group. The following is a full description of the message
when it is issued alone.
code is the code
associated with the failure:
- 4
- There is no active CP-capable link to the preferred server.
- 8
- See the sense code in message IST1280I to determine the reason
for the failure.
- 12
- The switch to the preferred network node server specified by the
MODIFY VTAMOPTS,NNSPREF command currently being processed has been
terminated because a later MODIFY VTAMOPTS,NNSPREF command has superseded
it.
- 16
- The switch of CP-CP sessions to the adjacent CP specified on the
NNSPREF start option failed because the adjacent CP is actually an
end node. CP-CP sessions between adjacent end nodes (EN) are not allowed.
System action
Operator response
The operator response is determined by the
error code:
- 4
- Activate a CP-capable link from the EN to the preferred network
node server.
- 8
- Save the console output and contact system programmer to determine
causes for failure of CP-CP session activation attempt.
- 12
- No action is necessary.
- 16
- Contact the system programmer to help determine the correct value
for the NNSPREF start option.
