Setting the multipath policy for DS8000 and Storwize Family systems

When using the IBM® Storage Enhancements for VMware vSphere Web Client, the recommended multipath policy for DS8000® and Storwize® Family (including SAN Volume Controller) storage systems is Round Robin.

If you are using VMware ESXi servers of version 5.5 or later, the Round Robin multipath policy is enforced by default. However, if you are using earlier ESX or ESXi versions, the Fixed policy is chosen by default, and it is recommended to change the multipath policy on those servers to Round Robin.

For information about how to change the default multipath policy enforcement for earlier ESX or ESXi versions, refer to article 1017760 on the VMware Knowledge Base website.
