Re: PWRDWNSYS

No.

During a backup, when the OS asks for data off the disk, the disk
controller will return the data from the cache if it's in there prior to
retrieving it from the disk.

This topic ended up, as it should have, focused on flushing cache. As I
think about it, if ENDSBS *ALL does not completely flush the disk cache and
it isn't completely flushed until a PWRDWNSYS *CNTRLD is done then every
restricted state backup ever done is potentially invalid UNLESS all the
save commands somehow save the information in the disk cache. Thoughts,
again?
