RE: Cache Battery question

Look around for the procedure to ensure cache written to disk before you
replace the battery - I believe it's D6005500 is start and D6005501 is
completed successfully - **I THINK** - can't find the doc right in front
of me.

That "exact" same situation occurred here with county government.

Their problem was NO current backups with a recent change of management.
It took 8 days for them to come back and I don't even know if they ever
got the entire system restored properly.

This was a large multi-LPAR system running many applications.

It made the front page of the local paper including names of the folks
in the computer area...

One experience with cache batteries makes me careful about replacing

We had one that needed to be replaced so we put in a service call.

For some reason the CE didn't shut the machine down normally he simply
forced he power off. Whatever was in cache memory did not get written to
disk so we ended up with several damaged objects, requiring us to reload
them from tape.

So my only warning is make sure you power the machine down normally
before you replace the battery.
