ibstat - query basic status of InfiniBand device(s)
ibstat [-d(ebug)] [-l(ist_of_cas)] [-s(hort)] [-p(ort_list)]
[-V(ersion)] [-h] <ca_name> [portnum]
ibstat is a binary which displays basic information obtained from the
local IB driver. Output includes LID, SMLID, port state, link width
active, and port physical state.
It is similar to the ibstatus utility but implemented as a binary
rather than a script. It has options to list CAs and/or ports and
displays more information than ibstatus.
list all IB devices

InfiniBand device name
port number of InfiniBand device
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.
"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.
-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.

ibstat -l # list all IB devices
ibstat -p # show port guids
ibstat mthca0 2 # show status of port 2 of ’mthca0’
