In my system with latest version of SE that it is disabled by default.  Tested this in labs..  The issue seems that 'SYMAPI_TRACK_SIZE_32K_COMPATIBLE' which is set to ENABLE. You can disable this so that you could see the device size depending on the symmetrix model.  * /var/symapi/config/options ** # # Parameter:            SYMAPI_TRACK_SIZE_32K_COMPATIBLE # # Allowed values:       ENABLE | DISABLE # # Default value:        DISABLE # # Description:          Specifies how to report device sizes. ENABLE reports #                       device size in terms of 32 KB tracks. DISABLE reports #                       device sizes in their native mode, depending on the #                       Symmetrix array model. # #SYMAPI_TRACK_SIZE_32K_COMPATIBLE = DISABLE   ** If your Query is Answered, please mark this Question as Answered **
