mdmonitord - daemon to monitor metadevices SYNOPSIS
/usr/sbin/mdmonitord [-t time_interval] DESCRIPTION
The mdmonitord utility is part of Solaris Volume Manager. It monitors and checks RAID1 (mirrors), RAID5 and hot spares. There are two methods for checking: o At fixed time intervals. o When a RAID-1 (mirror), RAID-5, or hot spare fails. A failure generates an error event which triggers a check of these metade- vices. 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 recommended as a starting point. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. ATTRIBUTES

Since frequent probes can affect performance, it is recommended that the intervals between probes be limited. The mdmonitord service is managed by the service management facility, smf(5), under the service identifier: svc:/system/mdmonitor Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using the svcs(1) command. SunOS 5.11 25 Jul 2004 mdmonitord(1M)
