two disks failed

Hi ,

Two disks have failed at the same time on the celerra NS40 . They are both in the same raid group.  There are some iscsi luns on the failed RG  but data is not important.  I would like to destroy failed RG  ,    I  know that i need to delete iscsi luns and fs  before the destroy operation.

Is it possible that remove iscsli luns , fs , pools  on a  RG which has  two  failed drive ?

Do i need to  perform any operation on the celerra side ?

Thanks .
