Unattended IPL in progress after abnormal system end.
We are interested in knowing this object QSZPAVLI in library  QUSRSYS.

pls check & ensure that this should not happen in future.

Plz. anyone if u can tell what could have happened/. Now I am not able to
find the object QSZPAVLI  in my machine..
nor i am able to find this object on two similar 820 model machines which
we have...

Does momentary power off has anyhting to do with it.. ???? though we have
UPS but the cleaning staff could have tripped on the cable... this is a
remote possibilty but i just asked... tomorrow i will be able to tell for
sure whether the cleaning staff had gone in the room or not...


Thanks a lot..
Santosh.
