medstat(1M) System Administration Commands medstat(1M)NAMEmedstat - 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.
