So I’m following along with vmpete’s http://vmpete.com/2012/09/20/multipathing-in-vsphere-with-the-dell-equallogic-multipathing-extension-module-mem/ mem install…
You really do have to put the server in maintenance mode or it won’t let you run setup.pl 🙂
Like Pete suggests I used a full command string to setup. I looked up the definition of -nohwiscsi that means
Ignore any supported iSCSI offload network cards, and use
only the VMware software iSCSI initiator. If the
configuration script detects iSCSI offload network cards, it
will use this capability by default unless this flag is set.
My string looks like setup.pl -configure -server=10.56.1.1 -vswitch=vSwitch4 –mtu=9000 -nics=vmnic4,vmnic5,vmnic10,vmnic11 -ips=10.10.1.75,10.10.1.76,10.10.1.77,10.10.1.78 -netmask=255.255.0.0 -vmkernel=iscsi -nohwiscsi –enableswiscsi
Ok, that setup.pl is awesome! You won’t realize how cool it is until you had to create iscsi nics the old fashion way! Thanks #Equallogic
So I wanted to show the team how this script ran, in order to do it again you need to unbind the physical network cards from the iSCSI VMKernel
so starting with vmk1 (vmk0 usually is the management interface)
ESXi 5.0: # esxcli iscsi networkportal remove -n vmk1 -A vmhba33
Then I needed to install the Multipathing Extension Module…
Wow, piece of cake!
