NAME

6       IBNODES - show InfiniBand nodes in topology
7

SYNOPSIS

9       ibnodes [options] [<topology-file>]
10

DESCRIPTION

12       ibnodes  is  a script which either walks the IB subnet topology or uses
13       an already saved topology file and  extracts  the  IB  nodes  (CAs  and
14       switches).
15

OPTIONS

17       -C, --Ca <ca_name>    use the specified ca_name.
18
19       -P, --Port <ca_port>    use the specified ca_port.
20
21       -t,  --timeout  <timeout_ms>  override  the  default  timeout  for  the
22       solicited mads.
23
24       -h, --help      show the usage message
25
26       --config, -z  <config_file> Specify alternate config file.
27          Default: /etc/infiniband-diags/ibdiag.conf
28
29   Local port Selection
30       Multiple port/Multiple CA support: when no IB device or port is  speci‐
31       fied  (see  the  "local  umad parameters" below), the libibumad library
32       selects the port to use by the following criteria:
33
34          1. the first port that is ACTIVE.
35
36          2. if not found, the first port that is UP (physical link up).
37
38          If a port  and/or  CA  name  is  specified,  the  libibumad  library
39          attempts  to  fulfill  the  user request, and will fail if it is not
40          possible.
41
42          For example:
43
44              ibaddr                 # use the first port (criteria #1 above)
45              ibaddr -C mthca1       # pick the best port from "mthca1" only.
46              ibaddr -P 2            # use the second (active/up) port from the first available IB device.
47              ibaddr -C mthca0 -P 2  # use the specified port only.

FILES

50   CONFIG FILE
51       /etc/infiniband-diags/ibdiag.conf
52
53       A global config file is provided to set some of the common options  for
54       all tools.  See supplied config file for details.
55
56   NODE NAME MAP FILE FORMAT
57       The  node  name map is used to specify user friendly names for nodes in
58       the output.  GUIDs are used to perform the lookup.
59
60       This  functionality  is  provided  by  the  opensm-libs  package.   See
61       opensm(8) for the file location for your installation.
