This plugin checks all volumes and sends an alarm if one or more do not have a SnapMirror
relation.
Volumes which are offline, restricted or unknown, are skipped. You can set
--verbose to see which volumes are skipped.
To explicitly exclude one or several volumes you can use the arguments
--exclude=<regex> and/or --include=<regex>. Specific vservers can be
included or excluded this way, since the vserver's name is prefixed to the
instance-name and can be matched using a pattern like --include=^vserv01:.
In the same way specific volumes can be excluded, an example for all vol0's
--exclude=:vol0$.
