Hi, This is my first mail here so please accept my apologies if this the wrong mailing list. I have the following setup on which I'm observing connectivity issues with an ISCSI target: 4 ESXi servers (5.5) 1 ISCSI target implementation based on targetcli (Linux xxx-iscsi-vm 3.13-1-amd64 #1 SMP Debian 3.13.10-1 (2014-04-15) x86_64 GNU/Linux) The ESXi servers are connected to the ISCSI target via a dedicated network (JUMBO frames enabled). After the initial setup everything seemed to be working fine, the device was recognized by the ESX servers and I was able deploy/create VMs on the VMFS formatted ISCSI datastore. However, after using the setup for a while (eg. after a few days) the hosts started losing connectivity to ISCSI and the device now shows as inactive (Dead or Error state) in the ESXs. >From the ISCSI side, using dmesg I get messages similar to the following: May 20 16:08:45 sof-24378-iscsi-vm kernel: [419952.703493] iSCSI Login negotiation failed.

You can find the full log in the link below: http://pastebin.com/AqqJaYVX Could you please provide some help on identifying whether this problems comes from the ESX side or ISCSI target and possible solutions/workarounds? Many thanks for your time and help!
