OPTIONS="-B"
# DEBUG mode
#  This option specifies a debug option.
#  These options are not normally needed.
#  The number following -d selects the debug
#  option to enable as follows:
#  OPT   Description
#  ---    -----------------
#  0  - Ignore other SM nodes.
#  1  - Force single threaded dispatching.
#  2  - Force log flushing after each log message.
#  3  - Disable multicast support.
#  4  - Put OpenSM in memory tracking mode.
#  10.. Put OpenSM in testability mode.
#  none, no debug options are enabled.
# OPTIONS="$OPTIONS -d 1"

# LMC
#  This option specifies the subnet's LMC value.
#  The number of LIDs assigned to each port is 2^LMC.
#  The LMC value must be in the range 0-7.
#  LMC values > 0 allow multiple paths between ports.
#  LMC values > 0 should only be used if the subnet
#  topology actually provides multiple paths between
#  ports, i.e. multiple interconnects between switches.
#  OpenSM defaults to LMC = 0, which allows
#  one path between any two ports.
# OPTIONS="$OPTIONS -l 0"

# MAXSMPS
#  This option specifies the number of VL15 SMP MADs
#  allowed on the wire at any one time.
#  Specifying -maxsmps 0 allows unlimited outstanding SMPs.
#  Without -maxsmps, OpenSM defaults to a maximum of
#  four outstanding SMP.
OPTIONS="$OPTIONS -maxsmps 0"

# REASSIGN_LIDS
#  This option causes OpenSM to reassign LIDs to all
#  end nodes. Specifying "REASSIGN_LIDS=yes" on a running subnet
#  may disrupt subnet traffic.
#  With "REASSIGN_LIDS=no", OpenSM attempts to preserve existing
#  LID assignments resolving multiple use of same LID.
# OPTIONS="$OPTIONS -r"

# SWEEP
#  This option specifies the number of seconds between
#  subnet sweeps.  Specifying SWEEP=0 disables sweeping.
#  OpenSM defaults to a sweep interval of 10 seconds.
# OPTIONS="$OPTIONS -s 10"

# TIMEOUT
#  This option specifies the time in milliseconds
#  used for transaction timeouts.
#  Specifying -t 0 disables timeouts.
#  Without -t, OpenSM defaults to a timeout value of
#  200 milliseconds.
# OPTIONS="$OPTIONS -t 200"

# OSM_LOG
#  This option defines the log to be the given file.
#  By default the log goes to /tmp/osm.log, which isn't very suitable
#  for a distribution, so we override it by default here.
#  For the log to go to standard output use OSM_LOG=stdout.
OPTIONS="$OPTIONS -f /var/log/opensm.log"

# QoS
#  This option enable QoS support in opensm
# OPTIONS="$OPTIONS -Q"

# QoS_POLICY
#  This option sets the file from which to load the QoS policy
# OPTIONS="$OPTIONS -Y /etc/rdma/qos_policy"

# VERBOSE
#  This option increases the log verbosity level.
#  The "-v" option may be specified multiple times
#  to further increase the verbosity level.
#   "-V" option sets the maximum verbosity level and
#   forces log flushing.
#   The "-V" is equivalent to "-vf 0xFF -d 2".
# OPTIONS="$OPTIONS -v 0x00"

# ROUTING_ENGINE
#  This option chooses the routing engine to use instead of the default
#  algorithm Min Hop
#  Supported engines are: updn, file, ftree, lash, dor
# OPTIONS="$OPTIONS -R updn"

# ROOT_GUID_FILE
#  This option only allowed when UPDN algorithm is activated
#  It specifies the guid list file from which to fetch the root node guid list
#  The file contain in each line only one valid guid
# OPTIONS="$OPTIONS -a /etc/rdma/root_guids"

# CN_GUID_FILE
#  This option only allowed when UPDN algorithm is activated
#  It specifies the guid list file from which to fetch the compute node
#  guid list
#  The file contain in each line only one valid guid
# OPTIONS="$OPTIONS -u /etc/rdma/cn_guids"

# GUID
#  This option specifies the local port GUID value
#  with which OpenSM should bind.  OpenSM may be
#  bound to 1 port at a time.
#  If GUID given is 0, opensm would list the available guids and wait for 
#  the user to select one (which obviously is no use in an init script)
#  Without -g, OpenSM trys to use the default port.
# OPTIONS="$OPTIONS -g <guid in hex>"

# PRIORITY
#  This option specifies the SM's PRIORITY.
#  This will effect the handover cases, where master
#  is chosen by priority and GUID.  Range goes
#  from 0 (lowest priority) to 15 (highest).
OPTIONS="$OPTIONS -p 15"

# OSM_CACHE_DIR
#  There is no command line option to opensm to set this, it can only be set
#  as an environment variable.
OSM_CACHE_DIR=/var/cache/opensm

# CACHE_OPTIONS
#  Cache the given command line options into the file
#  OSM_CACHE_DIR/opensm.opts for use next invocation
#  Set to '--cache-options' or '-c' in order to enable
# OPTIONS="$OPTIONS -c"
