NAME
volwatch - Monitor the Logical Storage Manager (LSM) for failure events
SYNOPSIS
/usr/sbin/volwatch [ mail-address ... ]
DESCRIPTION
The volwatch script monitors the Logical Storage Manager, waiting for
exception events to occur. It then sends mail via mailx(1) to the lo-
gin(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 in-
serted 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 por-
tions 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.
