Since configurations for SGeRAC may be complex to configure and maintain, it is strongly
recommended that you use Hewlett-Packard’s high availability consulting services to ensure a
smooth installation and rollout.
Contact your HP representative to inquire about high availability consulting. Because there may
be changes in firmware requirements as new hardware is released, you should work with your
HP representative to ensure that you have the latest firmware revisions for disk drives, disk
controllers, LAN controllers, and other hardware.

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
