rdma system help
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.
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.
