DESCRIPTION

22   rdma system set - set RDMA subsystem network namespace mode
23   rdma system show - display RDMA subsystem network namespace mode
24       NEWMODE - specifies the RDMA subsystem mode. Either exclusive or
25       shared.  When user wants to assign dedicated RDMA device to a particu‐
26       lar network namespace, exclusive mode should be set before creating any
27       network namespace. If there are active network namespaces and if one or
28       more RDMA devices exist, changing mode from shared to exclusive returns
29       error code EBUSY.
30
31       When RDMA subsystem is in shared mode, RDMA device is accessible in all
32       network namespace. When RDMA device isolation among multiple network
33       namespaces is not needed, shared mode can be used.
34
35       It is preferred to not change the subsystem mode when there is active
36       RDMA traffic running, even though it is supported.

EXAMPLES

40       rdma system show
41           Shows the state of RDMA subsystem network namespace mode on the
42           system.
43
44       rdma system set netns exclusive
45           Sets the RDMA subsystem in network namespace exclusive mode. In
46           this mode RDMA devices are visible only in single network names‐
47           pace.
48
49       rdma system set netns shared
50           Sets the RDMA subsystem in network namespace shared mode. In this
51           mode RDMA devices are shared among network namespaces.
