VMware - Configure iSCSI Port Binding for Round Robin Multipathing

1) Create VMkernel adapter for each port being used for iSCSI traffic (2 for the example)

Select Host > Configure > Virtual Switches > Add Networking

Choose VMkernel Network Adapter

Select vSwitch to assign VMkernel or create new vSwitch if one doesn't exist

Name VMkernel and continue

Assign static IP or use DHCP

 

2) Edit each adapter to use only one port; the first iSCSI VMkernel using the first port, the second iSCSI VMkernel using the second

Select VMkernel and click edit

Under Teaming and failover, override the Failover order and set the second adapter as unused

After saving the VMkernel should show itself only pointing to one port

Repeat for the second VMkernel, setting the second port as Active and the first as Unused

 

3) Assign iSCSI Port Binding

Select the newly created and configured VMkernels 

Rescan iSCSI adapter to pick up additional paths

 

4) Repeat steps 1-3 to add additional paths to iSCSI adapter.  Zadara recommends a minimum of 4 paths, with 8 being optimal.  For more information see https://zadarastorage.zendesk.com/hc/en-us/articles/360000502523
