P6000 - Diskzero Confirmation

Is there a way to confirm the diskzero process has completed successfully?

I kicked off the DiskZero process on my P6000 Equalogic SAN a couple of weeks ago and every time I try to run it again, it says the process has already started. Its' been this way for over a week.

I cant tell whether the diskzero process keeps cycling over and over again or if it will eventually end. If it does eventually end - is there anyway to confirm it's status?
