In this video, VMware engineer will show you the configuration of iSCSI port bindings.
Nice video find on the VMware KBTV which I'd like to share here. It's the process of activating an iSCSI initiator (via GUI) and binding the vmk nics (via CLI ..) .
You'll see the configuration steps, but also the testing with ESXTOP command line. Also he will do a check to make sure that the configuration is correct by creating a disk file on a datastore. While doing this, he unplugs one cable to simulate a failure. As you'll see there will be 100% packet drop, and the failover to vmnic2 will happens. The creation of the VMDK file will continue and the traffic will flow through the vmnic2 only.
As for now, the ESX(i) 4.1 does not allow to do those bindings via the GUI, so the only way to achieve this configuration is to pass those CLI commands from the console.
Those commands are:
To list the vmknic connected to the vmkernel port:
esxcli swiscsi nic list -d vmhba34
To add a vmknic to the vmkernel port:
esxcli swiscsi nic add –n vmk0 –d vmhba34
To be sure that it's the vmhba34 or vmhba33 just have a look when you enable your iSCSI initiator. You'll be able to see it via your VI client.
Enjoy the video…
