Configuring Virtual Disks From The Host - HP 6400/8400 User Manual

6. Run vxdctl enable to notify VxVM of the changes.
7. Verify the configuration of VxVM as shown in
(the output may be slightly different depending on your VxVM version and the array
configuration).

By default, the EVA I/O policy is set to Round-Robin. For VxVM 4.1 MP1, only one path is used
for the I/Os with this policy. Therefore, HP recommends that you change the I/O policy to
Adaptive in order to use all paths to the LUN on the primary controller.
iopolicy" shows the commands you can use to check and change the I/O policy.
Example 4 Setting the iopolicy
# vxdmpadm getattr arrayname EVA8400 iopolicy

# vxdmpadm setattr arrayname EVA8400 iopolicy=adaptive
# vxdmpadm getattr arrayname EVA8400 iopolicy
