ITYM disable the VTOC index. I wouldn't want to do it that way.
I think that what Kees suggested is a better solution. Tell GRS
not to propagate the ENQ.

If you are going to go the amaspzap route but do not want to
disable/enable the vvds, there is a simpler way of cleaning up the
vvds. There is a "VVDS is Dirty" bit in the VTOC Format 4 record. Use
Superzap to display its current state (there is a special Dataset
Name that accesses the needed Format 4 record and gives you full
access to the VTOC). Now do the Dataset rename, run IEHPROGM, and zap
the byte to flip the bit on. The operating system will see the bit
set and rebuild the VVDS for you. Note that the dirty bit might be
for a dirty VTOC but I think that the VVDS will will be rebuilt in
this case. Also the Dataset's Format 1 record can be ZAPPED which
will delete it for you and the VTOC will be updated to compensate due
to the dirty flag.
