32 Configuring iSCSI Connectivity with VMware vSphere 6 and Dell PS Series Storage | TR1075
9. On the Ready to complete page, review the setting and select Finish.
The datastore is now available for use by this ESXi host. To enable other ESXi hosts to access this
datastore, it will be necessary to update the volume access controls to include those other hosts, and then
perform a rescan of the iSCSI storage adapter on that host.
8.1.4 Step 4: Enabling VMware native multipathing with Round Robin
By configuring the iSCSI software initiator in the previous steps, now we can take advantage of the
VMware native MPIO by enabling Round Robin. This advanced feature, combined with the fan-out
intelligent design of the PS Series group, allows for greater and better bandwidth utilization.
1. From the vSphere Web Client homepage, select Storage, and then select the recently added
datastore.
2. From that datastores page, select the Manage tab, then the Settings button, and finally click on
Connectivity and Multipathing.
3. Select the hosts to which the datastore is mounted to, and then click the Edit Multipathing button
to the lower right.
4. From the drop-down menu on the Edit Multipathing Policies, select Round Robin, and click OK.
This will configure the initiator to utilize all available paths to the volume for reading and writing
I/O for this volume.
Note: These steps needs to be completed for all existing and any new volumes that you want the Round
Robin policy to apply to, and on each host in the cluster.
Now the multiple paths that exist to the volume show a Status of Active (I/O) for all paths.
