Did you run CPSYNTAX on the changed SYSTEM CONFIG file after making the change 
and before the IPL?  If I remember correctly from home, CPSYNTAX is on MAINT's 
193 disk.

Double check your change for proper REXX comment syntax, in other words: proper 
opening chars "/*" and closing chars "*/".  If the closing characters are not 
correct, all the rest of the SYSTEM CONFIG file is treated as a comment.

I always include at the top of our SYSTEM CONFIG a line like:
Say 'Beginning SYSTEM CONFIG processing from MAINT CF1.'
and another at the very end like:
Say 'Ending SYSTEM CONFIG processing from MAINT CF1.'
The first "say" confirms (on the OPERATOR console) which config file is 
executing, and the last "say" confirms that the whole thing was processed.

Check the OPERATOR console for config file processing errors.  Consider 
including the statement "TOLERATE_ERRORS OFF" (check the manual for the syntax 
and usage, that may be a little off).

Subject: IPL SOFT WAIT PROBLEM



I have a running z/VM 5.3 for quite a long while.

I just edit the system config, to comment out 2 lines of define AND grant
vswitch.

Now I can't ipl the system up again.

Any suggestions to recover from this ? I have an old RES volume somewhere, I
can ipl up from that volume, but how to I migrate those latest data from my
current VMRES ?

Please help.

Regards Lim ML
