medstat(1M)		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 informa‐
		      tive 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 configured  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.

FILES
       /etc/lvm/meddb	 Contains  the	mediator data for a host that has been
			 selected as a mediator host.

EXIT STATUS
       The following exit values are returned:

       0     Successful completion.

       >0    An error occurred.
