ibnetdiscover Command

Discovers the InfiniBand topology.


ibnetdiscover [-d][-e][-v][-s][-l][-g][-H][-S][-R][-C ca_name][-P ca_port][-t timeout][-V][--node-name-map map][-p][-h][topology]



This InfiniBand command performs InfiniBand fabric discovery and outputs a human readable topology file. Nodes, node types, node descriptions, links, port numbers, port LIDs, and GUIDs are displayed. The output is directed to a topology file, if the file name is specified.

The output of the topology file follows this basic format for each node:

devid=device _ID_in_hex
Switch ports_total "type-nodeGUID_in_hex" # "NodeDescription" base port 0 lid LID lmc 0
Ca ports_total "type-nodeGUID_in_hex" # "NodeDescription"
[port] "type-nodeGUID_in_hex"[port](portGUID_in_hex) # "NodeDescription" lid LID widthspeed
[port] "type-nodeGUID_in_hex"[port](portGUID_in_hex) # "NodeDescription" lid LID widthspeed

For example:

Switch  36 "S-0021283a8389a0a0" # "Sun DCS 36 QDR switch localhost" enhanced port 0 lid 15 lmc 0
[23]    "H-0003ba000100e388"[2](3ba000100e38a) # "nsn33-43 HCA-1" lid 14 4xQDR

The following table describes the options to the ibnetdiscover command and their purposes:

Sets the debug level. Can be used several times to increase the debug level.
Displays send and receive errors.
Provides verbose output.
Shows more information.
Lists the connected nodes.
Shows the grouping and switch external ports correspondence.
Lists the connected channel adapters.
Lists the connected switches.
Lists the connected routers.
Uses the specified channel adapter name.
Uses the specified channel adapter port.
Overrides the default timeout.
Displays the version information.
Reads the node name map file.
Returns a list of connected ports, including status information:
  • LID

  • portnum

  • GUID

  • link width

  • link speed

  • NodeDescription

Provides help.

The following example shows how to discover the InfiniBand fabric topology with the ibnetdiscover command.

Note - The output for your InfiniBand fabric will differ from that in the example.

# ibnetdiscover
# Topology file: generated on Sat Apr 13 22:28:55 2002
# Max of 1 hops discovered
# Initiated from node 0021283a8389a0a0 port 0021283a8389a0a0
Switch  36 "S-0021283a8389a0a0" # "Sun DCS 36 QDR switch localhost" enhanced port 0 lid 15 lmc 0
[23]    "H-0003ba000100e388"[2](3ba000100e38a) # "nsn33-43 HCA-1" lid 14 4xQDR
Ca      2 "H-0003ba000100e388" # "nsn33-43 HCA-1"
[2](3ba000100e38a)      "S-0021283a8389a0a0"[23] # lid 14 lmc 0 "Sun DCS 36 QDR switch localhost" lid 15 4xQDR
