Native Multipathing, Veritas DMP, and Related Features
The HP-UX 11i v3 I/O subsystem provides multipathing and load balancing by default.
This is often referred to as native multipathing. Veritas Volume Manager (VxVM)
version 5.0 and Dynamic Multipathing (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
collection at http://docs.hp.com.
