mdmonitord(1M)

NAME

     mdmonitord - daemon to monitor metadevices

SYNOPSIS

     /usr/sbin/mdmonitord [-t time_interval]

DESCRIPTION

     The mdmonitord utility is part of Solaris Volume Manager. It
     checks  the  accessibility  of  the physical components of a
     metadevice. There are two methods for checking metadevices:

        o  At fixed time intervals.

        o  When a metadevice fails. Metadevice failure  generates
           an  error event which triggers a check of all metadev-
           ices.

OPTIONS

     The following options are supported:

     -t    Time interval in seconds.  The  default  value  is  0,
           which  causes  probes  to occur only upon an error. If
           you want to run mdmonitord at a  regular  interval,  a
           value  of  1800  (seconds,  every half hour) is recom-
           mended as a starting point.

EXIT STATUS

     The following exit values are returned:

          0     Successful completion.

          >0    An error occurred.

NOTES

     Since frequent probes can affect performance, it  is  recom-
     mended that the intervals between probes be limited.

     This daemon is started  at  boot  time  by   S95svm.sync  in
     /etc/rc2.d.
