DMP is portion of Veritas (Symantec) Volume Manager/Storage Foundation. You only mentioned SVM, so I don't know that you have that installed. Check the support matrix to be sure your arrays and cards are supported.
If you have Sun HBAs or certain compatible HBAs, you can use MPxIO (STMS). For Solaris 9, that's part of the SAN Foundation Suite. Download from sun and install. It contains documents on configuration.
