How to enable zBoost PAV Optimizer on z/OS

Hi Team,

I am new to VMAX performance enhancement. We are having the Model : VMAX-1(20K) and MCL is 5876.282 and also showing SYMM_VMAX_OPTIMIZER on the available feature. But when I try to enable it on z/OS i m getting below error message.

F SCF,DEV,OPTIMIZE ENABLE

     ***************

Invalid Command Wording; Found: Optimize

Skipping to END of Command

Device Command failed

Anybody having why this happened

Kind regards,

Antony
