You do not say if you have Sequent's Volume Manager (SVM)...It was created for the purpose of providing logical volumes, striping, and mirroring..... Utilizing the "built-in" features of the database vendor's db usually does NOT improve performance (much)....SVM enables you to localize "hot-spots" and handle them ON-LINE!....I would suggest you talk w/the Sequent hot-line and/or you local rep.
