Explanation
VTAM® issues
this message in response to a DISPLAY TRL,TRLE=trlename,DEVSTATS
command when trlename represents an IBM® 10GbE RoCE Express® interface. VTAM attempted to collect 10GbE
RoCE Express statistics
for trlename, but failed to do so because of timing
conditions or because the hardware could not successfully process
the request.
In the message text:
- trlename
- The name of the resource that was specified on the DISPLAY TRL
command.
System action
Processing continues. No 10GbE RoCE Express statistics for trlename are
displayed.
Operator response

- Save the console log.
- Review the network activity when the DISPLAY TRL,TRLE=trlename,DEVSTATS
command was issued.
- Perform the problem determination steps below.

Problem determination
Review the console log to see whether
you can determine the reason for the command failure.
- The problem might be that the last TCP/IP stack that was using
the 10GbE RoCE Express interface
issued a VARY TCPIP,,STOP command for the 10GbE RoCE Express interface. If this is the case, activate
the 10GbE RoCE Express interface
and issue the DISPLAY TRL,TRLE=trlename,DEVSTATS
command again.
- Other command failures might indicate a hardware failure. If this
problem is persistent, perform the following steps:
- If a VTAM internal trace
is not active, start a VTAM internal
trace by using the MODIFY TRACE,TYPE=VTAM,OPT=TCPOPTS,MODE=INT command.
- Enable a CSDUMP trigger for the next occurrence of message IST2402I
by using the MODIFY CSDUMP,MESSAGE=IST2402I command.
- Issue the DISPLAY TRL,TRLE=trlename,DEVSTATS
command to cause message IST2402I to be issued again.
- Save the console log and the dump generated by CSDUMP. Contact
the IBM support center.
