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 particu-
       lar 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 name-
           space.

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