System Administration Commandsmdmonitord(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:

  • At fixed time intervals.
  • When a metadevice fails. Metadevice failure generates an error event which triggers a check of all metadevices.

OPTIONS

 

-t
Time interval in seconds. Recommended probe interval 1800 seconds (1/2 hour). The default value is 0, which causes probes to occur only upon an error.

EXIT STATUS

 

The following exit values are returned:

0
Successful completion.
>0
An error occurred.

NOTES

 

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

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