They are instructed to power off the array because there's a microscopic
chance that the battery will explode, you know how it is in America. ;-)
It's really OK to change it with the power on but your cache is of
course not protected if your power should fail during the 10 seconds it
takes to switch the battery. The engineers are usually flexible when it
comes to schedule a routine task like that but if it bothers you that
they power down the array, ask them not to.
You can reset the battery age at any time with "raidutil -c device -R".

You could buy the V60x and V65x Intel-based servers, priced as Dell but
you get the same fine service. Soon you will have AMD64 servers also. :-)
Now I'm totally off-topic so I should stop here.
