vmware esx iscsi

The config looks ok. Maybe you have an ip conflict or target conflict that the ESXi detects and offlines the connection

    Hi,

    I'm trying to connect an vmware esxi hosts to an stgt target.

    I have this little config:

    <target iqn.2014-04.rbdstore.example.com:loop>
        driver iscsi
        backing-store /var/tgt/store1
        scsi_id 00010005
    </target>

    The problem is that I get vmware error when I try to mount the
    datastore.


    From vmkernel.log I see the following:
