Configuring ISCSI port binding on vSphere using CLI

Configuring Port Binding on vSphere 5.0 Using CLI

Run the following commands from the vSphere 5.0 host CLI to bind the VMkernel network adapter to the  iSCSI adapter:

esxcli iscsi networkportal add --nic vmk0 --adapter vmhbaXX

esxcli iscsi networkportal add --nic vmk1 --adapter vmhbaXX

Where vmk0 and vmk1 are the VMkernel network adapters compatible with iSCSI port binding requirements.  You can get the list of VMkernel network adapters connected to  all vSwitches by using  the command   

esxcfg-vmknic –l

vmhbaXX  is the software iSCSI adapter vmhba ID. You can verify the binding details by using the  following command: 

esxcli iscsi networkportal list --adapter vmhbaXX.

Then rescan the software iSCSI adapter to verify that multiple paths are available for iSCSI LUNs.

Configuring Port Binding on vSphere 4.x Using CLI

To enable vmknic-based multipathing for software iSCSI, run the following CLI commands:

esxcli swiscsi nic add --nic vmk0 --adapter vmhbaXX

esxcli swiscsi nic add --nic vmk1 --adapter vmhbaXX

Where  vmk0 and  vmk1 are the VMkernel network adapters  compatible with iSCSI port binding requirements. You can get the list of VMkernel network  adapters connected to all vSwitches by using the command 

esxcfg-vmknic -l.

vmhbaXX is the software iSCSI adapter vmhba ID.  After configuring port binding, you can verify the binding details by using the following command: 

esxcli swiscsi nic list --adapter vmhbaXX. 

Then rescan the software iSCSI adapter to verify that multiple paths are available for iSCSI LUNs.
