RE: UPS Maintenance

This is what we do here. We use the shutdown routines provided with
some of our software such as MQ to do a clean shutdown of those programs

We then do a ENDSBS *ALL *IMMED and wait until the system is in a
restricted state.

We then do the PWRDWNSYS command. If you are worried about the Cache
you can always do the following command...

PWRDWNSYS OPTION(*CNTRLD) DELAY(300) RESTART(*NO)

The 5 minute delay should allow you to make sure that the cache has bee
cleared out before the system shuts down.

Subject: UPS Maintenance

We are going to take our 520 down this weekend to replace an aging
battery in the UPS. Except for the time my boss accidentally unplugged
the processor from the UPS, this will be the first time that the system
has been turned off since it was installed over two years ago.

I read the Info Center section on shutting down the system, which, in
summary, includes stopping or holding jobs and queues and doing a power
down *Immed. Does the cache battery need to be flushed? I checked out
the STRSST option and it said that, if the cache battery is forced into
an error state, it would have to be replaced. Also, it seemed to
indicate that the system would no longer use the cache (since the
battery would be in an error state); not a good thing obviously.

Thanks.
