IBHOSTS(8) OpenIB Diagnostics IBHOSTS(8) NAME
IBHOSTS - show InfiniBand host nodes in topology SYNOPSIS
ibhosts [options] [<topology-file>] DESCRIPTION
ibhosts is a script which either walks the IB subnet topology or uses an already saved topology file and extracts the CA nodes. OPTIONS
-C, --Ca <ca_name> use the specified ca_name. -P, --Port <ca_port> use the specified ca_port. -t, --timeout <timeout_ms> override the default timeout for the solicited mads. -h, --help show the usage message --config, -z <config_file> Specify alternate config file. Default: /etc/infiniband-diags/ibdiag.conf Local port Selection Multiple port/Multiple CA support: when no IB device or port is specified (see the "local umad parameters" below), the libibumad library selects the port to use by the following criteria: 1. the first port that is ACTIVE. 2. if not found, the first port that is UP (physical link up). If a port and/or CA name is specified, the libibumad library attempts to fulfill the user request, and will fail if it is not possible. For example: ibaddr # use the first port (criteria #1 above) ibaddr -C mthca1 # pick the best port from "mthca1" only. ibaddr -P 2 # use the second (active/up) port from the first available IB device. ibaddr -C mthca0 -P 2 # use the specified port only. FILES
CONFIG FILE /etc/infiniband-diags/ibdiag.conf A global config file is provided to set some of the common options for all tools. See supplied config file for details. NODE NAME MAP FILE FORMAT The node name map is used to specify user friendly names for nodes in the output. GUIDs are used to perform the lookup. This functionality is provided by the opensm-libs package. See opensm(8) for the file location for your installation.
