(DMP) from Symantec are supported on HP-UX 11i v3, but do not
provide multipathing and load balancing; DMP acts as a pass-through
driver, allowing multipathing and load balancing to be controlled by the
HP-UX I/O subsystem instead.
When you upgrade a system to HP-UX 11i v3, the I/O subsystem by
default will start performing load balancing and multipathing for all
multipath devices (whether or not they are managed by VxVM/DMP, and
whether or not you decide to migrate the system to agile addressing); you
do not have to take any additional steps to make this happen.
For more information about multipathing in HP-UX 11i v3, see the white
paper HP-UX 11i v3 Native Multipathing for Mass Storage, and the
Logical Volume Management volume of the HP-UX System
Administrator’s Guide in the HP-UX 11i v3 Operating Environments
