-------------------------------------------------
-The iSCSI Initiator for Red Hat Enterprise Linux
-------------------------------------------------
-
-**Prerequisite:**
-
--  Package ``iscsi-initiator-utils-6.2.0.873-35`` or newer must be
-   installed
-
--  Package ``device-mapper-multipath-0.4.9-99`` or newer must be
-   installed
-
-**Installing:**
-
-Install the iSCSI initiator and multipath tools:
-
-   ::
-
-       # yum install iscsi-initiator-utils
-       # yum install device-mapper-multipath
-
-**Configuring:**
-
-#. Create the default ``/etc/multipath.conf`` file and enable the
-   ``multiapthd`` service:
-
-   ::
-
-       # mpathconf --enable --with_multipathd y
-
-#. Add the following to ``/etc/multipath.conf`` file:
-
-   ::
-
-       devices {
-               device {
-                       vendor                 "LIO-ORG"
-                       hardware_handler       "1 alua"
-                       path_grouping_policy   "failover"
-                       path_selector          "queue-length 0"
-                       failback               60
-                       path_checker           tur
-                       prio                   alua
-                       prio_args              exclusive_pref_bit
-                       fast_oi_fail_tmo       25
-                       no_path_retry          queue
-               }
-       }
-
-#. Restart the ``multipathd`` service:
-
-   ::
-
-       # systemctl reload multipathd
-
-**iSCSI Discovery and Setup:**
-
-#. Discover the target portals:
-
-   ::
-
-       # iscsiadm -m discovery -t -st 192.168.56.101
-       192.168.56.101:3260,1 iqn.2003-01.org.linux-iscsi.rheln1
-       192.168.56.102:3260,2 iqn.2003-01.org.linux-iscsi.rheln1
-
-#. Login to target:
-
-   ::
-
-       # iscsiadm -m node -T iqn.2003-01.org.linux-iscsi.rheln1 -l
-
-**Multipath IO Setup:**
-
-The multipath daemon (``multipathd``), will set up devices automatically
-based on the ``multipath.conf`` settings. Running the ``multipath``
-command show devices setup in a failover configuration with a priority
-group for each path.
-
-::
-
-    # multipath -ll
-    mpathbt (360014059ca317516a69465c883a29603) dm-1 LIO-ORG ,IBLOCK
-    size=1.0G features='0' hwhandler='1 alua' wp=rw
-    |-+- policy='queue-length 0' prio=50 status=active
-    | `- 28:0:0:1 sde  8:64  active ready running
-    `-+- policy='queue-length 0' prio=10 status=enabled
-      `- 29:0:0:1 sdc  8:32  active ready running
-
-You should now be able to use the RBD image like you would a normal
-multipath’d iSCSI disk.
