       ibchecknode - validate IB node and report errors
       ibchecknode [-h] [-v] [-N | -nocolor] [-G] [-C ca_name] [-P
       ca_port] [-t(imeout) timeout_ms] <lid|guid>
       Check connectivity and do some simple sanity checks for the
       specified node.  Port address is a lid unless -G option is used to
       specify a GUID address.
       -G      use GUID address argument. In most cases, it is the Port
       GUID.
               Example:
               "0x08f1040023"
       -v      increase the verbosity level
       -N | -nocolor use mono rather than color mode
       -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.
