NAME
     mpccdump, mpccmon - dump MPCC

SYNOPSIS
     mpccdump  [ -l ] [ ports ] mpcc

DESCRIPTION
     /usr/lib/mpccdump performs a memory dump of Harris's Multi-
     Protocol Communication Controller (MPCC).  This utility will
     dump the kernel structures associated with the specified
     MPCC, the full memory of the MPCC, and allow you to request
     a breakout of any or all of the ports on the MPCC board.
     The dump can not be performed if any other MPCC is in the
     process of being dumped or downloaded.  See dlmpcc(1M) for
     information on downloading an MPCC.

     If you specify the command with just the mpcc argument, then
     mpccdump will provide a full dump the specified MPCC board
     and a breakout of every port on that MPCC.  The valid values
     for mpcc range from 0-15.  The ports option allows you to
     limit the breakout to one or more ports.  Valid port numbers
     are in the range of 0-31.  The -l flag is used to produce
     another listing from a previous dump.  The ports option will
     be ignored if the -l flag is present.  The new listing will
     be identical to the original.

     /usr/lib/mpccmon is a program that monitors all MPCCs in the
     system and invokes mpccdump for any MPCC that is about to
     enter a panic situation.  Mpccmon starts up whenever all of
     the MPCC boards are downloaded by dlmpcc.

EXAMPLES
     The following command line orders mpccdump to generate a
     full dump of MPCC board 2:
          mpccdump 2

     The next command line orders mpccdump to limit its port
     breakout to ports 0 and 3 on board 2:
          mpccdump 0 3 2

NOTES
     If a dump was requested by the user rather than the MPCC, it
     is possible that the MPCC memory portion may not match the
     port breakout information exactly.  This is because we allow
     other processes to run on the MPCC while we are dumping the

     memory.  Since we temporarily suspend those other processes
     while breaking out a port, the port information is a true
     snapshot.
