I keep spare drives and a spare raid card in my rack. Which makes it
really easy to avoid such issues with remote hands. If available where
your servers are, if not, might consider such :)

You can definitely do that, but I tend to prefer to not just yank an
active drive out. Though not sure offhand how to deactivate it before
hand, I assume there is a way, but maybe not.

eBay to the rescue most times. One nice thing about older hardware, you
can get spare parts for days on the cheap from eBay. Its kinda my new
way of doing things, vs always buying new. Though there is a balance to
that, not everything new, and not everything old or used.
