For what it's worth I am not in the storage dept,
but we do have thousands of drives in 3PAR systems.
For all the cases I am aware of, there has only been predictive drive failures.
First time I discovered a 3PAR in degraded state I was concerned as we did not get an alert,
but the 3PAR will vacate the drive slowly in the background (low priority?)
and then fail the drive/alert HP.
The process seems slow, but I guess a rebuild would have much higher priority.
I'm pretty sure it's yes on low priority, 3Par seems to do all background tasks on a 20% or less threshold (ie if I compare what AO or multiple tuneld jobs does as far as data movement on the backend to what I can push with a few svmotions it's in the 15-20% range). I also only have predictive failures to go by as far as time to rebuild (that shows to me that their monitoring is quite good as we've had hard failures on all of our previous arrays).
