System Administration Commands                        medstat(1M)



NAME
     medstat - check the status of mediator  hosts  for  a  given
     diskset

SYNOPSIS
     /usr/sbin/medstat [-q] -s setname


DESCRIPTION
     If a specified diskset has been  configured  for  mediators,
     medstat  attempts  to contact these hosts to see if they are
     accessible and returns the results of the communication.

OPTIONS
     -q             This optional argument disables the  printing
                    of  informative  text.  When  used  with  -q,
                    medstat  still  prints  error  messages   and
                    returns a result code.


     -s setname     Specifies the name  of  a  diskset  on  which
                    medstat will work.


EXAMPLES
     Example 1  Checking diskset


     This example checks the  mediator  hosts  for  the  selected
     diskset.


       # medstat -s relo-red




     The name of the diskset is  relo-red.  The  medstat  command
     prints  the  status for each mediator host. Additionally, if
     the mediator quorum is  met,  either  through  a  ``golden''
     mediator  host  or  because  half+1  of  the  mediator hosts
     respond, the exit code is 0. If the quorum is not met,  then
     the  exit  code is 1. If no mediator hosts have been config-
     ured for the named diskset, the exit code is 2.  The  status
     field will contain one of the following values: Unreachable,
     Bad,  Fatal,  or  Ok,   where   Unreachable   indicates   an
     RPC/communication  problem,  Bad  indicates  an error in the
     mediator data, Fatal indicates any  other  error  condition,
     and Ok indicates no error conditions.
