5. From the drop-down menu, select the appropriate MPIO policy for the volume. Make sure the chosen
policy is supported or Windows will revert to the current default policy.
5.3.2 Using the MPCLAIM command
To change the default load balance policy on a single volume, open a command prompt or PowerShell
window with elevated (administrator) privileges (commands will work in both).
Note: The load balance policy cannot be changed from round robin to failover only using the MPCLAIM
command. MPCLAIM only supports switching from failover only to round robin.
To list all MPIO volumes on the system, enter:
mpclaim –s –d
In this example, the load balance policy is set to round robin (RR) for disks 0 and 1; and to failover only (FOO)
for disk 2.
Listing MPIO volumes
The syntax to change the load balance policy on a specific volume is:
mpclaim –l –d <disk #> <0-7>
