IBND_DISCOVER_FABRIC(3) OpenIB Programmer's Manual IBND_DISCOVER_FABRIC(3)NAME
ibnd_discover_fabric, ibnd_destroy_fabric, ibnd_debug
ibnd_show_progress - initialize ibnetdiscover library.
SYNOPSIS
#include <infiniband/ibnetdisc.h>
void ibnd_destroy_fabric(ibnd_fabric_t *fabric)
void ibnd_debug(int i)
void ibnd_show_progress(int i)
int ibnd_set_max_smps_on_wire(int i)
DESCRIPTIONibnd_discover_fabric() Discover the fabric connected to the port speci‐
fied by ibmad_port, using a timeout specified. The "from" and "hops"
parameters are optional and allow one to scan part of a fabric by spec‐
ifying a node "from" and a number of hops away from that node to scan,
"hops". This gives the user a "sub-fabric" which is "centered" any‐
where they chose.
ibmad_port must be opened with at least IB_SMI_CLASS and
IB_SMI_DIRECT_CLASS classes for ibnd_discover_fabric to work.
ibnd_destroy_fabric() free all memory and resources associated with the
fabric.
ibnd_debug() Set the debug level to be printed as library operations
take place.
ibnd_show_progress() Indicate that the library should print debug out‐
put which shows it's progress through the fabric.
ibnd_set_max_smps_on_wire() Set the number of SMP´s which will be
issued on the wire simultaneously.
RETURN VALUEibnd_discover_fabric() return NULL on failure, otherwise a valid
ibnd_fabric_t object.
ibnd_destory_fabric(), ibnd_debug() NONE
ibnd_set_max_smps_on_wire() The previous value is returned
EXAMPLES
Discover the entire fabric connected to device mthca0 , port 1.
int mgmt_classes[2] = {IB_SMI_CLASS, IB_SMI_DIRECT_CLASS};
struct ibmad_port *ibmad_port = mad_rpc_open_port(ca, ca_port,
mgmt_classes, 2); ibnd_fabric_t *fabric = ibnd_discover_fab‐
ric(ibmad_port, 100, NULL, 0); ... ibnd_destroy_fabric(fab‐
ric); mad_rpc_close_port(ibmad_port);
Discover only a single node and those nodes connected to it.
... str2drpath(&(port_id.drpath), from, 0, 0); ...
ibnd_discover_fabric(ibmad_port, 100, &port_id, 1); ...
