ibhosts [options] [<topology\-file>]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
ibhosts is a script which either walks the IB subnet topology or uses an
|
|
already saved topology file and extracts the CA nodes.

.\" Explanation of local port selection

|
|
.SS Local port Selection
|
|
.sp
|
|
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:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.INDENT 0.0
|
|
.IP 1. 3
|
|
the first port that is ACTIVE.
|
|
.IP 2. 3
|
|
if not found, the first port that is UP (physical link up).
|
|
.UNINDENT
|
|
.sp
|
|
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.
|
|
.sp
|
|
For example:
|
|
.INDENT 0.0
|
|
.INDENT 3.5
|
|
.sp
|
|
.nf
|
|
.ft C
|
|
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.
