IBNETDISCOVER(8) OpenIB Diagnostics IBNETDISCOVER(8)NAMEibnetdiscover - discover InfiniBand topology
SYNOPSISibnetdiscover [-d(ebug)] [-e(rr_show)] [-v(erbose)] [-s(how)] [-l(ist)]
[-g(rouping)] [-H(ca_list)] [-S(witch_list)] [-C ca_name] [-P ca_port]
[-t(imeout) timeout_ms] [-V(ersion)] [-h(elp)] [<topology-file>]
DESCRIPTIONibnetdiscover performs IB subnet discovery and outputs a human readable
topology file. GUIDs, node types, and port numbers are displayed as
well as port LIDs and NodeDescriptions. All nodes (and links) are dis‐
played (full topology). Optionally this utility can be used to list the
current connected nodes. The output is printed to the standard output
unless a topology file is specified.
OPTIONS-l, --list
List of connected nodes
-g, --grouping
Show grouping
-H, --Hca_list
List of connected HCAs
-S, --Switch_list
List of connected switches
-s, --show
Show more information
COMMON OPTIONS
Most OpenIB diagnostics take the following common flags. The exact list
of supported flags per utility can be found in the usage message and
can be shown using the util_name -h syntax.
# Debugging flags
-d raise the IB debugging level.
May be used several times (-ddd or -d -d -d).
-e show send and receive errors (timeouts and others)
-h show the usage message
-v increase the application verbosity level.
May be used several times (-vv or -v -v -v)
-V show the version info.
# Addressing flags
-D use directed path address arguments. The path
is a comma separated list of out ports.
Examples:
"0" # self port
"0,1,2,1,4" # out via port 1, then 2, ...
-G use GUID address argument. In most cases, it is the Port GUID.
Example:
"0x08f1040023"
-s <smlid> use 'smlid' as the target lid for SM/SA queries.
# Other common flags:
-C <ca_name> use the specified ca_name.
-P <ca_port> use the specified ca_port.
-t <timeout_ms> override the default timeout for the solicited mads.
Multiple CA/Multiple Port Support
When no IB device or port is specified, the port to use is selected 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 user request is attempted to
be fulfilled, and will fail if it is not possible.
