RE: i5 Cache Battery

And, put this in your pipe and smoke it - the system doesn't check
voltage but assumes certain environmental conditions based on a
known-good number of days of a battery of that type.  Generally you get
about 1000 days on a new battery.  If it's hot where the system is, the
life decreases some.  

If you're on an old system that you have no maintenance on, search the
archives for my procedures and part numbers for using cordless phone
batteries acquired at the Wal-Mart to do your own maintenance.  Also -
if you REALLY don't care, just disconnect and reconnect it once it's
gone to failed - the system senses the battery disconnect and assumes
you hooked-up a new one.

The cache battery ensures that cache is written to disk in the event of
power disruption.  Therefore you can't rely on the power supply.
Stick this in your regular periodic stuff to check on your iSeries:

If those cache batteries go bad your system will stop caching and will
take a SERIOUS performance hit.

i5 Cache Battery






Hello All, 

We just got a warning today on our i5 that the cache battery is dying. 

That seems to be such an odd component to still be required on the
iSeries 

with today's technology. 

Since everything else is run off the power supply, why would a cache 
battery still be needed in today's day and age ? :-)

We've run into this problem regularly starting back from the 170 days. 

I'm interested to hear any comments. 

Regards,
Richard Schoen
