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.
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.
See attributes(5) for descriptions of the following attributes:

Solaris Volume Manager Administration Guide
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.
