NAME

6       IBHOSTS - show InfiniBand host nodes in topology
7

SYNOPSIS

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

DESCRIPTION

12       ibhosts  is  a script which either walks the IB subnet topology or uses
13       an already saved topology file and extracts the CA nodes.
14

OPTIONS

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

FILES

53   CONFIG FILE
54       /etc/infiniband-diags/ibdiag.conf
55
56       A global config file is provided to set some of the common options  for
57       all tools.  See supplied config file for details.
58
59   NODE NAME MAP FILE FORMAT
60       The  node  name map is used to specify user friendly names for nodes in
61       the output.  GUIDs are used to perform the lookup.
62
63       This  functionality  is  provided  by  the  opensm-libs  package.   See
64       opensm(8) for the file location for your installation.
