iSCSI Target in Ubuntu 16.04LTS with multipath as datastore for VMware
Create disk:
mkdir /iscsi_disks
dd if=/dev/zero of=/iscsi_disks/disk01.img count=0 bs=1 seek=1.8T
configure 2 network interfaces for multipath
nano /etc/network/interfaces
auto ens10f0
iface ens10f0 inet static
address 10.17.0.10
netmask 255.255.0.0
network 10.17.0.0
broadcast 10.17.255.255
gateway 10.17.255.254

Set the reverse path in loose mode:

net.ipv4.conf.all.rp_filter=2
Enable iscsitarget
nano /etc/iscsitarget
