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>


tgt-admin -s

    LUN information:
        LUN: 0
            Type: controller

        ALL

ls -l /var/tgt/store1
-rw-rw-rw- 1 root root 21474836480 Jun 16 16:15 /var/tgt/store1


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


From vmkernel.log I see the following:

Hi,

Thanks for your response.

After troubleshooting, I found out that the problem was an MTU problem,
so I got packet loss between the nodes.

Kind regards,
