# NAME
#
# -u SECONDS
# Define a duration for the test. 86400 seconds if not specified.
#
+# -p SECONDS
+# Define a max failover period. 10 minutes if not set.
+#
# -w
# Only run the workloads; no failure will be introduced.
+# -v, -s are ignored in this case.
+# -r
+# Workloads dry run for several seconds; no failures will be introduced.
+# This option is useful to verify the loads.
+# -u is ignored in this case
+# -m
+# Reboot victim nodes simultaneously.
+#
#
# ASSUMPTIONS
#
# Each target has a failnode, so that workloads can continue after a power
# failure.
#
+# CRM could be configured by 2 ways:
+# 1.
# Targets are automatically failed back when their primary node is back. This
# assumption avoids calling CRM-specific commands to trigger failbacks, making
# this script more CRM-neural.
+# 2.
+# Targets are not automatically failed back when their primary node is back.
+# CRM-specific command is executed to trigger failbacks.
#
# A crash dump mechanism is configured to catch LBUGs, panics, etc.
#
# WORKLOADS
#
-# Each client runs the same set of MPI and non-MPI workloads. These
+# Each client runs set of MPI and non-MPI workloads. These
# applications are run in short loops so that their exit status can be waited
# for and checked within reasonable time by ha_wait_loads.
+# The set of MPI and non-MPI workloads are configurable by parameters:
+# ha_nonmpi_loads
+# default set: dd, tar, iozone
+# ha_mpi_loads
+# default set: ior, simul, mdtest
+#
+# The number of clients run MPI loads is configured by parameter
+# ha_mpi_instances. Only one client runs MPI workloads by default.
+#
+# MPI workloads can be run from several users. The list of users to use is
+# configured by parameter ha_mpi_users, default is "mpiuser".
