Hi Debbie

WOW - I printed all that information from InfoCenter - it's not rocket science. Card locations, everything. I've done both a 270 and an i5 - anyone want a CE cheap? NOT

For the i5 there are even nice videos at infoCenter - FOR the service personnel, as well as civilians such as I - and one does not have to take the whole blasted machine apart to get at these things.

If I can do it, anyone from IBM with a little instruction should be able to do it. Sheesh!!

As to popping the battery out - they don't just pop - unless there is a secret - the paperwork says to squeeze the bracket - yeah, sure - with a vicegrip, thank you very much. Fortunately these reinforced circuit boards are tough!!

Next time, call LarryB - he probably knows more than most CE's ever will these days!!

We just had to replace our batteries Friday night. The CE who came out to
do this wasn't even quite sure where the cards were located. He pulled just
about every panel off of both of our towers to locate the cards. He called
our usual CE, who was working at another customer & IBM to determine exactly
how to swap the batteries. One of the set of batteries had to be hot swapped
to get them recognized & one had to be cold swapped. He pulled both cards
all the way out. When he started using his car key to pop the batteries out
of the first card it made me nervous & I offered him our set of screwdrivers
to use instead. I was so glad that I had done a full save before he got
there!! The man had my nerves on edge. What should have been a 5 minute
job took over an hour and a half.

With mirroring you can loose several drives, an entire cage, or a
controller and still not go down, that is if you mirror at least at the
controller level. However if you loose two drive in the same raid set,
or any upstream hardware, you are down until repair. If you loose two
drives in the same raid set, you are reloading that ASP/entire system.

As for replacing the battery, you should force the error to disable and
flush the cashe to be safe, that is to prevent loosing data if the power
should fail in the minute you have the battery out. (It does happen.)
Old controllers you had to remove the card to get to the battery, new
cards are accessable with the card in place, in fact I think you can get
to them with the covers on.

Honestly I've lost several disk drives under RAID. However, I've
experienced no downtime because of it. The drives were hot replaced and
the users didn't notice a thing. Just trying to find out what the big
advantage is to mirroring. I thought with mirroring when you lost a
drive, you still didn't lose data, but you did have to drop the system
to replace the drive. I hope I am misinformed because I fail to see the
advantage in that. Perhaps that's just how it used to be?
