ASM rebalance question

Hi,

using 12.2 RAC with 12.2 RDBMS OL7.

We use NetApp LUNs to extend diskgroups by adding one when needed. The diskgroups has external redundancy.

I observed following issue together with our Storage administrator:

If I add a new LUN to diskgroup it will properly rebalanced from ASM view,

here the output of "asmcmd lsdsk -k":
