- At some level of MVS/SP, definitely prior to V4, MVS was changed to do
- a catalog lookup for SYS1.LOGREC, and use the cataloged version if
- found. If not cataloged, then it must be on the IPL volume.
-
- As someone else already replied, you can just rename the existing one,
- allocate and initialize a new one, and IPL. Don't forget to dump the
- data from the old one before you scratch it. And yes, don't scratch
- the old one before IPLing. It's opened only at IPL time. Also note
- that you can't move SYS1.LOGREC because it has absolute disk addresses
- in it. I heard a story of one site that reorganized sysres and ended
- up with logrec data in the middle of an SMP dataset because they
- didn't re-init logrec.
