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:

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:

HOSTS

List of hosts, used if -h option not supplied.

HOSTS_FILE

File containing list of hosts, used in absence of -f and -h.

PORTS

List of ports, used in absence of -t and -p.

PORTS_FILE

File containing list of ports, used in absence of -t and -p.

FF_MAX_PARALLEL

Maximum concurrent operations.
