Can I assume this is talking only about the ADSM mirroring and not the
OS mirroring?

Hi Reinhard,
I can confirm absolutely that partial page writes do occur in the real world. We
had to instances of this on one server within a few days. Unfortunately, we wer
en't able to recover. We had the server option MIRRORWRITE LOG set to the defaul
t of PARALLEL at the time, and the ADSM server did not recover as it should have
. If we had had MIRRORWRITE LOG set to SEQUENTIAL, the database would have recov
ered, I believe. And there have been changes made to the recovery logic (sorry,
I can't remember which version) that should enabled the database to recover even
if set to PARALLEL.
regards,
Trevor
