.SH "DESCRIPTION"
|
|
.SS rdma system set - set RDMA subsystem network namespace mode
|
|
|
|
.SS rdma system show - display RDMA subsystem network namespace mode
|
|
|
|
.PP
|
|
.I "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.
|
|
