HP 6400.8400 Enterprise Virtual Array - Manual (Page 61)

6. Run vxdctl enable to notify VxVM of the changes.
7. Verify the configuration of VxVM as shown in Example 3 “Verifying the VxVM configuration”
(the output may be slightly different depending on your VxVM version and the array
configuration).
Example 3 Verifying the VxVM configuration
# vxddladm listsupport all | grep HP

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. Example 4 “Setting the
I/O policy” shows the commands you can use to check and change the I/O policy.
Example 4 Setting the I/O policy
# vxdmpadm getattr arrayname EVA8400 iopolicy
ENCLR_NAME DEFAULT CURRENT
============================================
EVA84000 Round-Robin Round-Robin
# vxdmpadm setattr arrayname EVA8400 iopolicy=adaptive
# vxdmpadm getattr arrayname EVA8400 iopolicy
ENCLR_NAME DEFAULT CURRENT
============================================
EVA84000 Round-Robin Adaptive
Configuring virtual disks from the host
The procedure used to configure the LUN path to the array depends on the FCA driver. For more
information, see
