TRAPMSG (STOP dutifully drops the virtual machine into CP Read, but CONCEAL does nothing at that point.

Can you use TRAPMSG to issue an IPL command.

Re: Automatic recovery from virtual machine abend
Can you use TRAPMSG to issue an IPL command. Was that a question? From the TRAPMSG doc, I don't see any way to issue a specific command. That sure could be useful for high-availability SVMs - even as a poor-man's automation (limited to the messages trapped by TRAPMSG).

Re: Automatic recovery from virtual machine abend
It sure could. I hate doing such things as putting IPL or LOGOFF commands on the stack. Getting a CP READ posted does give you the 15-minute FORCE so long as there is no SECUSER. If there is one, it ought to be monitoring for VM and CP READS and doing the appropriate thing.
