Title:
  Shutdown hangs with active iscsi sessions

Status in systemd package in Ubuntu:
  Won't Fix

Bug description:
  This is a duplicate of the bug listed here:
  https://bugs.launchpad.net/bugs/1569925 for 16.04.

  That bug was automatically closed though the problem still persists.
  I am opening this bug for 16.10 in hopes that it will catch somebody's
  attention.

  I have 4 servers running the latest 16.10 updates.

  Each server is connected to NetApp storage using iscsi software
  initiator. There are a total of 56 volumes spread across two NetApp
  arrays. Each volume has 4 paths available to it which are being
  managed by device mapper.

  While logged into the iscsi sessions all I have to do is reboot the
  server and I get a hang.

  I see a message that says:

    "Reached target Shutdown"

  followed by

    "systemd-shutdown[1]: Failed to finalize DM devices, ignoring"

  and then I see 8 lines that say:

    "connection1:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***"
    "connection2:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***"
    "connection3:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***"
    "connection4:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***"
    "connection5:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***"
    "connection6:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***"
    "connection7:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***"
    "connection8:0: ping timeout of 5 secs expired, recv timeout 5, last rx 4311815***, last ping 43118164**, now 4311817***"
    NOTE: the actual values of the *'s differ for each line above.
