IBPRINTCA(8)                OpenIB Diagnostics               IBPRINTCA(8)

NAME         top

       ibprintca.pl - print either the ca specified or the list of cas
       from the ibnetdiscover output

SYNOPSIS         top

       ibprintca.pl [-R -l -C <ca_name> -P <ca_port>]
       [<ca_guid|node_name>]

DESCRIPTION         top

       Faster than greping/viewing with an editor the output of
       ibnetdiscover, ibprintca.pl will parse out and print either the CA
       information for the specified CA or a list of all the CAs in the
       subnet.

       Finally, ibprintca.pl will also reuse the cached ibnetdiscover
       output from some of the other diag tools which makes it a bit
       faster than running ibnetdiscover from scratch.

OPTIONS         top

       -l     List the CAs (simply a wrapper for ibhosts).

       -R     Recalculate the ibnetdiscover information, ie do not use
              the cached information.  This option is slower but should
              be used if the diag tools have not been used for some time
              or if there are other reasons to believe that the fabric
              has changed.

       -C <ca_name>    use the specified ca_name for the search.

       -P <ca_port>    use the specified ca_port for the search.
