NAS Group Error in FMA/VE

Hello.

I do have 10 archiving destination shares for archiving each destination has 2TB size.

I did create a Nas Group adding the 10 destinations to the group

In the archiving policy i specify that group for destination

Archiving was working good until the first destination got full, it stop doing archiving becasue target was full. To make it work i did delete from the NAS Group configuration the first destination and then the archiving process work again using the second repository of the group.

questions?

why the archiving process only saw the first repository of the group and when it got full didnt take the second repository?

should this has to be automatic??

Thanks for your answers
