Need help on PsApiGroup API for cloning volume

Hi,

I am trying to clone a volume by using volumeClone function of PsApiGroup class, but I want to pass other parameters to it like snap-reserve space.

I am using 2.1.2 sdk, the volumeClone function does not take these extra parameters. The firmware on array is 5.2

But when I tried to clone same volume using web GUI, it allowed me to do so. By checking Audit logs I found the command to be as below:

volume select vol-10-0-idc-b108-idcupdb10 clone clone read-write online snap-reserve 100% snap-warn 10% snap-depletion volume-offline iscsi-alias clone thin-provision thin-min-reserve 10% thin-growth-warn 85% thin-growth-max 100%  

Is there any API which allows me to do so? Or am I using older SDK? Or is above command not executed using one single API but rather several APIs?
