Hello Richard, I believe the reason for your error message in using SHUTTRAP is that SHUTTRAP can only issue CMS commands and not CP commands. Is the message associated with your SHUTTRAP issuing a CP command? I had the same problem when my message was a CP command. As a test for SHUTTAP I issued the CMS command 'Q DISK' and it worked with no error message.
Hope this helps. Raymond E.

In my first simpleminded try, the results were mixed. The signal shutdown did indeed trigger the command included with the shuttrap command. Then I got this: SHUTTRAP: Shutdown in 900 seconds DMSITP143T Addressing exception occurred at 81056162 in system routine WAITRD; re-IPL CMS 15:07:56 * MSG FROM RSCHUH1 : DMSDIE3550I All APPC/VM and IUCV paths have been severed. HCPGIR450W CP entered; disabled wait PSW 000A0000 80F3F752 There is nothing in the documentation that would lead me to believe that this is normal; however, the documentation consists solely of the HELP file and is pretty sparse in this area. I tried reassembling the module with the same results. z/VM 6.1 Service Level 1002 CMS 25, Service Level 002 Regards, Richard Schuh
