Explanation
VTAM® issues
this message when a CSDUMP was taken but diagnostics for the associated IBM® 10GbE RoCE Express® interface could not be taken. 
In
the message text:resource
The value specified as the RNICTRLE trigger for CSDUMP processing.
reason
The reason the diagnostics could not be taken and can be one of
the following:TRLE NOT FOUND
resource does not exist.
TRLE NOT AN RNIC
resource exists and was found, but the TRLE
does not represent a 10GbE RoCE Express interface.
Diagnostics can be produced only when at least one TCP/IP stack has
an active connection to the 10GbE RoCE Express interface.
TRLE NOT ACTIVE
resource represents a 10GbE RoCE Express TRLE, but the TRLE is not in a state
where diagnostics can be produced.
UNSUPPORTED ENVIRONMENT
The message specified as a trigger for a CSDUMP and a 10GbE RoCE Express diagnostic dump is issued
in an execution environment which prevents VTAM from generating the 10GbE RoCE Express diagnostic dump.

System action
Processing continues.

Operator response
Depending on the value of reason,
take the following action:
TRLE NOT FOUND, TRLE NOT AN RNIC, and UNSUPPORTED
ENVIRONMENTContact the system programmer.

TRLE NOT ACTIVE
Ensure that the CSDUMP
is requested when at least one stack has connectivity to the 10GbE
RoCE Express interface.

System programmer response
Depending on the value of reason,
take the following action:
TRLE NOT FOUND and TRLE
NOT AN RNICDetermine the correct TRLE name to use for the 10GbE RoCE Express interface.
Instruct the operator to correct the RNICTRLE trigger value by
using the MODIFY CSDUMP command.

UNSUPPORTED ENVIRONMENT

Diagnostics
for the 10GbE RoCE Express interface
cannot be produced if the message that triggers a CSDUMP and a 10GbE
RoCE Express diagnostic
dump is issued in certain environments.If an alternate message can be used as the trigger, instruct the
operator to issue a MODIFY CSDUMP,MESSAGE=alternate_message,
RNICTRLE=resource command to change the message
trigger.
If only this message can be used as the trigger, instruct the
operator to issue a MODIFY CSDUMP,RNICTRLE=resource command
to take an immediate 10GbE RoCE Express diagnostic
dump, or create automation to take the immediate dump, when the message
is seen.

User response
None.

Problem determination
Not applicable.
