Solaris Volume Manager includes the /usr/sbin/mdmonitord daemon.
When a disk fails, Solaris Volume Manager detects the failure and generates an error. This
error event triggers the mdmonitord
daemon to perform a check
of RAID-1 (mirror) volumes, RAID-5 volumes, and hot spares. However, you can also
configure this program to actively check for errors at an interval that you specify.
How to Configure the mdmonitord Command for Periodic Error Checking
Edit the /lib/svc/method/svc-mdmonitor
script to add a
time interval for periodic checking.
Become superuser.
Open the /lib/svc/method/svc-mdmonitor
script in
the editor of your choice. Locate the following section in the script:
$MDMONITORD error=$? case $error in 0) exit 0 ;; *) echo "Could not start $MDMONITORD. Error $error." exit 0
Change the line that starts the mdmonitord command by adding a -t flag and the number of seconds between checks.
$MDMONITORD -t 3600 error=$? case $error in 0) exit 0 ;; *) echo "Could not start $MDMONITORD. Error $error." exit 0 ;; esac
Restart the mdmonitord command to activate your changes.
# svcadm restart system/mdmonitor
