Re: Cache battery questions

Thanks John. Information that is most interesting, but I am not in the loop at
work. By choice of sys admin. Seems I get to learn things by "the kindness of
strangers" <g>.

Quoting John Jones <chianime@xxxxxxxxx>:

1. Like this?

2. Yes, but may be difficult depending on your chassis and the controller.
Also may or may not be able to do it concurrent. Even if the RAID card
supports concurrent maintenance you may not be able to. Our most recent
round of replacements a few weeks ago revealed that. The batteries had
swollen with the heat and the CE was not able to replace them without risk
so we powered down.

BTW we're under maintenance and have never had an issue with having IBM do
the replacement. Battery availability has been problematic sometimes but
not having IBM do the actual swap and resetting of the counter in SST.

Just curious:

1) Is there a picture of the cache battery somewhere?
2) Is the cache battery potentially user replaceable?
