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 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 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  indi-
       cates 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.
