Re: Impending cache battery pack failure

Generally, the "impending failure" message is sent 90
days prior to the failure.  However, it is an
"estimate until failure" only.

To check on how many days, (note, days, not hours),
until this estimated failure depends on the OS level.

At V5R3, start system service tools, option 1 start a
service tool, option 7 - Hardware service manager and
then option 9 - Work with resources containing cache
battery packs.  Here you can see which IOA's have
batteries and also see information such as the power
on time, estimated time to warning, estimated time to
error, etc.

At V5R2 and earlier, Start system service tools,
option 1 start a service tool, option 4 -
Display/Alter/Dump, option 1 - Display/Alter storage,
option 2 - LIC data, Option 14 - Advanced Analysis and
select option 1 against BATTERYINFO.  Use options such
as -LIST to see resources, -INFO to get details of
cache battery.

You certainly do NOT want to wait until the battery
fails as your system will slow to a crawl.  It is also
a good idea to check on other RAID IOA's that you have
in the system.  If one has gone into warning state
now, others may no be far behind and you should
replace them all at once.

Make sure you perform a full system backup prior to
replacing the batteries - this is your RAID cache that
you are playing with.
