"SSD Over Provisioning Optimization" -- how long does it take?

Question summary:  How long does 'SSD Over Provisioning Optimization' really take?

Background:  I'm setting up some new servers with large disk arrays -- 6 x 1.6TB SSDs.  I want all my storage in one big raid10.

So... I've gone to hpssa during startup, and run this command:

=> ctrl slot=0 create type=ld drives=1I:1:1,1I:1:2,1I:1:3,1I:1:4,2I:1:5,2I:1:6 raid=10

That gets me a warning: 

"SSD Over Provisioning Optimization will be performed on the physical drives in this array. This process may take a long time and cause this application to appear unresponsive. Continue? (y/n)"

The aren't kidding about appearing unresponsive!  I'm 8+ hours in with no evidence of progress.  Can anyone advise about how long this is likely to take?  10 hours?  100?  1000?
