Radoslaw:
Thanks. My greater concern is loss of data. This system is very new and
not into production yet, so an IPL would be minimally "disruptive" for a
while (until after the operating system was installed and configured.
Since we are installing the operating system later this week, if it was
reformatting the volumes, that would be truly disruptive.

Does anyone know if adding PAV (alias) addresses to a configured DS6800
is disruptive of any real devices already configured and initialized on
the affected LCU?
IMHO yes. Usually you have 256 devices per CU. Base and aliases. So,
adding aliases means
CU reconfiguration, means some device must go to another CU. Since
such devices must go offline, it is disruptive.
There is further question: is the reformat required to do such
reconfiguration? "Disruptive" means simply offline-online, maybe it
causes IPL. Reformat means you LOSE your volumes and have to restore
them from backup.
