I dont use camcontrol, i use the mfiutil for the perc 5 controller. 

When i pulled a healthy drive from one of our old dells i would use mfiutil to fail the good drive before removing it. But that was just in the lab for testing as i have no need to remove a healthy drive from a system. 

Have not used camcontrol for a while now. Sorry dont know the answer to that.
