Optional Instructions for Multipathing 1. For multipath load balancing and failover using the VERITAS DMP driver, install VERITAS Volume Manager using the instructions given in the VERITAS Volume Manager installation and administrator guides, available from: www.VERITAS.com or http://docs.hp.com 2. The base VxVM package is installed as part of the HP-UX Operating System installation. To enable VxDMP, also install the following product bundle: Patch bundle B9116AA on the HP-UX 11i v1 or v2 application Software CD or DVD for the appropriate installed OS release NOTE: This is licensed software.
