volwatch - Monitor the Logical Storage Manager (LSM) for failure events
/usr/sbin/volwatch [mail-address...]
The volwatch script monitors the Logical Storage Manager, waiting for exception events to occur. It then sends mail via mailx(1) to the login(s) specified on the command line, or to the default user of root.
The volwatch script will call the volnotify command which waits for events to occur. Once an event occurs, a 15 second delay will be inserted before analyzing the failures and sending a mail notification. This prevents the recipient of mail from receiving too many separate messages for each event.
Once a failure event has been analyzed the following messages (or portions of them, depending on the type of failure) can occur:
Failures have been detected by the Logical Storage Manager: failed disks: medianame ...
failed plexes: plexname ...
failed volumes: volume_name ...
The contents of failed volumes may be corrupted, and should be restored from any available backups. To restart one of these volumes, so that you can restore it from backup, replace disks as appropriate, then use the command: volume -f start volume_name
You can then restore or reinitialize the volume.
