RDMA-SYSTEM(8)                                Linux                                RDMA-SYSTEM(8)

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 run-
       ning, 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.
