DESCRIPTION

The

nwmgr program is the uniﬁed command to administer all LAN and RDMA-based interfaces of HP-

UX. General information about the command as a whole can be found in the manual page nwmgr(1M).

This manual page describes

nwmgr as applied to the RDMA subsystem.

The

nwmgr RDMA subsystem allows you to:

• Display information about the RDMA adapters on the system.

• Display Reliable Connection information.

• Display InﬁniBand fabric topology information.

• Display and reset interface statistics.

• Reset the interface adapter.

• Download trace or performance ﬁrmware.

• Perform a linkloop-like packet send to check connectivity to an adapter.

• Perform Critical Resource Analysis on an adapter.

Operations other than

get and linkloop require hpux.network.config

authorization. For more

information about authorizations and Role-based Access Control, see rbac(5).

Operations

The

nwmgr command provides the following operations for the RDMA subsystem.

--cra Operation to perform Critical Resource Analysis on the interface.

--diag | --diagnose Operation to diagnose/test link connectivity.

-g | --get Operation to get/display interface settings.

-h | --help Operation to display help information.

-r | --reset Operation to reset interface or statistics.

--do | --download Operation to download the trace or notrace (performance) version of

the ﬁrmware onto the adapter.

Options

Beside operations, the following options are valid for the RDMA subsystem:

-A | --attribute Assigns attributes for an operation. For RDMA, this option can be used

with the diagnose operation.

nwmgr_rdma(1M) nwmgr_rdma(1M) Attributes that can be used for RDMA subsystem are described in the Attributes section below. -c | --class_instance Specifies the target interface on which the operation is to be performed. -it | --iteration Specifies how many test frames to send during a diagnose operation. The default is 3. -S | --subsystem Specifies the target subsystem for the operation. For the RDMA subsystem, the option argument is always rdma.
