Disabling SHARP on Specific Network Devices in OpenSM

Disabling SHARP on a specific network switch device can be performed using OpenSM device configuration file by performing the following:

  1. Define a port group with the specified network device in the port groups file. The group is specified by the pgrp_policy_file parameter in the OpenSM configuration file.
    For example:

    Copy

    port-group name: NON_SHARP_SWITCHES port-guid: 0x0002c90000000001 end-port-group

  2. Configure OpenSM to disable SHARP on the devices of the specified port groups in device configuration file specified by the device_configuration_file parameter in OpenSM configuration file.

    Copy
    Copied!
