NAME

       rdma-system - RDMA subsystem configuration

SYNOPSIS

       rdma [ OPTIONS ] sys  { COMMAND | help }

       OPTIONS := { -V[ersion] | -d[etails] }

       rdma system show

       rdma system set netns NEWMODE

       rdma system help

DESCRIPTION

   rdma system set - set RDMA subsystem network namespace mode
   rdma system show - display RDMA subsystem network namespace mode
       NEWMODE - specifies the RDMA subsystem mode. Either exclusive or shared.  When user wants to assign
       dedicated RDMA device to a particular network namespace, exclusive mode should be set before creating any
       network namespace. If there are active network namespaces and if one or more RDMA devices exist, changing
       mode from shared to exclusive returns error code EBUSY.

       When RDMA subsystem is in shared mode, RDMA device is accessible in all network namespace. When RDMA
       device isolation among multiple network namespaces is not needed, shared mode can be used.

       It is preferred to not change the subsystem mode when there is active RDMA traffic running, even though
       it is supported.

EXAMPLES

       rdma system show
           Shows the state of RDMA subsystem network namespace mode on the system.

       rdma system set netns exclusive
           Sets the RDMA subsystem in network namespace exclusive mode. In this mode RDMA devices are visible
           only in single network namespace.

       rdma system set netns shared
           Sets the RDMA subsystem in network namespace shared mode. In this mode RDMA devices are shared among
           network namespaces.
