I have a Dell Poweredge R310 w/ a PERC S100 RAID controller, and want to replace & add HDDs. The R310 backplane itself clearly supports hot-swapping, but I can't figure out if the PERC S100 supports it. I would assume so, but looking over the manual for the PERC S100/S300, it's a little unclear whether the PERC S100 supports how-swapping.
There's a section on page 25 that says this (emphasis mine):
CAUTION: A physical disk can be hot-swapped from a system only if the system has a PERC S300 adapter and a backplane that supports hot-swapping.
At first, this sounds clear that it's only for the S300. But I can't tell if it was in a generic context, and the important piece was the "backplane that supports hot-swapping" piece.
Why would the PERC S300 support hot-swapping, but not the S100?
Does anyone have a server w/ an S100 controller and confirm whether it supports hot-swapping?
Otherwise, what are the risks of attempting to hot-swap a single HD with a higher capacity drive, if it doesn't support hot-swapping? Are we talking risk of data loss, or just system shutdown?
