Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

This policy attempts to maximize overall I/O throughput from/to the
disks by dynamically scheduling I/O on the paths. It is suggested for
use where I/O loads can vary over time. For example, I/O from/to a
database may exhibit both long transfers (table scans) and short
transfers (random look ups). The policy is also useful for a SAN
environment where different paths may have different number of
hops. No further configuration is possible as this policy is
automatically managed by DMP.
In this example, the adaptive I/O policy is set for the enclosure enc1:
# vxdmpadm setattr enclosure enc1 \
iopolicy=adaptive
