+# quickly (before node.conn[0].timeo.login_timeout fires) because the network
+# layer or the target returns an error, iscsid may retry the login more than
+# node.session.initial_login_retry_max times.
+#
+# This retry count along with node.conn[0].timeo.login_timeout
+# determines the maximum amount of time iscsid will try to
+# establish the initial login. node.session.initial_login_retry_max is
+# multiplied by the node.conn[0].timeo.login_timeout to determine the
+# maximum amount.
+#
+# The default node.session.initial_login_retry_max is 8 and
+# node.conn[0].timeo.login_timeout is 15 so we have:

+# node.conn[0].timeo.login_timeout * node.session.initial_login_retry_max =
+#								120 seconds
+#
+# Valid values are any integer value. This only
+# affects the initial login. Setting it to a high value can slow
+# down the iscsi service startup. Setting it to a low value can
+# cause a session to not get logged into, if there are distuptions
+# during startup or if the network is not ready at that time.

+##################################
+
+# For software iscsi (iscsi_tcp) and iser (ib_iser) each session
+# has a thread used to transmit or queue data to the hardware. For
+# cxgb3i you will get a thread per host.
+#
+# Setting the thread's priority to a lower value can lead to higher throughput
+# and lower latencies. The lowest value is -20. Setting the priority to
+# a higher value, can lead to reduced IO performance, but if you are seeing
+# the iscsi or scsi threads dominate the use of the CPU then you may want
+# to set this value higher.
+#
+# Note: For cxgb3i you must set all sessions to the same value, or the
+# behavior is not defined.
