NAME

       opacabletest

       (Switch)  Initiates  or  stops  Cable  Bit  Error  Rate  stress  tests for Intel(R) Omni-Path Host Fabric
       Interface (HFI)-to-switch links and/or ISLs.

Syntax

       opacabletest [-C|-A] [-c  file] [-f  hostfile] [-h  'hosts'] [-n  numprocs]

       [-t portsfile] [-p  ports] [start|start_fi|start_isl|stop|stop_fi|
       stop_isl] ...

Options

       --help

                 Produces full help text.

       -C

                 Clears error counters.

       -A

                 Forces the system to clear hardware error counters. Implies -C.

       -c file

                 Specifies the error thresholds configuration file.  Default  is  /etc/opa/opamon.si.conf  file.
                 Only used if -C or -A specified.

       -f hostfile

                 Specifies the file with hosts to include in HFI -to-SW test. Default is /etc/opa/hosts file.

       -h hosts

                 Specifies the list of hosts to include in HFI -SW test.

       -n numprocs

                 Specifies the number of processes per host for HFI -SW test.

       -t portsfile

                 Specifies  the file with list of local HFI ports used to access fabrics when clearing counters.
                 Default is /etc/opa/ports file.

       -p ports

                 Specifies the list of local HFI ports used to access fabrics for counter clear.

                 Default is first active port. The first HFI in the system is 1. The first port on an HFI is  1.
                 Uses the format hfi:port,
                 for example:

                 0:0       First active port in system.

                 0:y       Port y within system.

                 x:0       First active port on HFI x.

                 x:y       HFI x, port y.

       start

                 Starts the HFI -SW and ISL tests.

       start_fi

                 Starts the HFI -SW test.

       start_isl

                 Starts the ISL test.

       stop

                 Stops the HFI -SW and ISL tests.

       stop_fi

                 Stops the HFI -SW test.

       stop_isl

                 Stops the ISL test.

       The  HFI -SW cable test requires that the FF_MPI_APPS_DIR is set, and it contains a pre-built copy of the
       mpi_apps for an appropriate message passing interface (MPI).

       The ISL cable test started by this tool assumes that the master Host Subnet Manager (HSM) is  running  on
       this  host. If using the Embedded Subnet Manager (ESM), or if a different host is the master HSM, the ISL
       cable test must be controlled by the switch CLI, or by Intel(R) Omni-Path Fabric Suite FastFabric on  the
       master HSM respectively.

Examples

       opacabletest -A start

       opacabletest -f good -A start

       opacabletest -h 'arwen elrond' start_fi

       HOSTS='arwen elrond' opacabletest stop

       opacabletest -A

Environment Variables

       The following environment variables are also used by this command:
