NAME

6       medstat - check the status of mediator hosts for a given diskset
7

SYNOPSIS

9       /usr/sbin/medstat [-q] -s setname
10
11

DESCRIPTION

13       If  a  specified  diskset  has  been  configured for mediators, medstat
14       attempts to contact these hosts to  see  if  they  are  accessible  and
15       returns the results of the communication.
16

OPTIONS

18       -q             This optional argument disables the printing of informa‐
19                      tive text. When used with -q, medstat still prints error
20                      messages and returns a result code.
21
22
23       -s setname     Specifies  the  name  of a diskset on which medstat will
24                      work.

31       This example checks the mediator hosts for the selected diskset.

34         # medstat -s relo-red

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