Bernie,

My personal rule is that failed drives, even if they are only hot spares
should be replaced as soon as possible.  Does this require expenditure of
funds beyond your SLOBs delegated limit?   If so, then hardware failure
replacement like this needs to be added to your authorization as a general
case.  The only e-mail you should have to send to get a replacement ordered
is to your favorite vendor.
