SCON-20L/22L/25L/28L/3074 Planning and Installation Guide
When enabled, this option causes only the foreground session to appear initially as
having a powered on device associated with it. As the user hot keys into the other sessions,
the SCON will forward the correct powered-on status to the host. For console sessions,
the result of appearing to be powered on, will result in the console sessions not being
varied active automatically.
When disabled, all sessions associated with an individual coax terminal will appear to
be powered on whenever the terminal is powered on and communicating with the SCON.
In this instance, all console sessions can be established, even though the user has not
viewed some of their sessions.
540-80 Error In Event Log
This error occurs when a host attempts to establish a path for which the SCON is not
configured.
540-81 Error In Event Log
A request to establish a path has been received but the path has already been established
by a different LPAR. This error usually indicates that Channel Path Filtering has not
been configured on the SCON and the device candidate list has not been properly
configured.
540-82 Error In Event Log
This error typically is associated with TN3270E clients not responding quick enough
for the channel when used with non-SNA SCON. Turn on the ‘reset session on non-
SNA SCON read timeout’ RPQ.
540-83 Error In Event Log
This error may result if a printer device attempts to use a non-SNA host session genned
as a console display.
540-84 Error In Event Log
This event indicates that channel path has been established and is not normally viewed
as an error event. Only if this event indicates that a connection was established from the
wrong LPAR would this be an error indication.
Unable To Communicate From One Of The Configured Hosts
Look in the Event Log for 540-81 errors indicating that the host device candidate list
has not been configured correctly. You may also look in the host IOCDS GEN for the
IODEVICE MACRO, Partition Parameter. If the path is defined to include multiple
partitions and the partition parameter is missing or specifies more than one partition,
there is an incorrect configuration of the device candidate list.
