Set Up Ports for iSCSI
Multipathing
With port binding,
you create a separate VMkernel port for each physical NIC using 1:1 mapping.
Verify that you are familiar
with iSCSI session removal. See
Removing iSCSI Sessions.
You can add all network
adapter and VMkernel port pairs to a single vSwitch. The
vSphere Storage
documentation explains in detail how to specify port binding.
In the examples below, specify
one of the options listed in
Connection Options for ESXCLI Host Management Commands
in place of
<conn_options>
.
- Find out which uplinks are available for use with iSCSI adapters.esxcli <conn_options> iscsi physicalnetworkportal list --adapter=<adapter_name>
- Connect the software iSCSI or dependent hardware iSCSI initiator to the iSCSI VMkernel ports by running the following command for each port.esxcli <conn_options> iscsi networkportal nic add --adapter=<adapter_name> --nic=<bound_nic>
- Verify that the ports were added to the iSCSI initiator by running the following command.esxcli <conn_options> iscsi networkportal list --adapter=<adapter_name>
- If there are active iSCSI sessions between your host and targets, discontinue them. See Removing iSCSI Sessions.
- Rescan the iSCSI initiator.esxcli <conn_options> storage core adapter rescan --adapter <iscsi adapter>
- To disconnect the iSCSI initiator from the ports, run the following command.esxcli <conn_options> iscsi networkportal remove --adapter=<adapter_name> --nic=<bound_nic>
