Veritas Storage Foundation Intelligent Storage Provisioning 5.0.1 Administrators Guide, HP-UX 11i v3, First Edition, November 2009

By tagging disks with a suitable attribute name and value such as reserved_for
and redo_log, you can use a confineto rule to ensure that the volume for a redo
log is only allocated space from those disks, as shown in the following example:
confineto "reserved_for"="redo_log"
Conversely when creating volumes that are not to be used for the redo logs, you
can specify an exclude rule, as shown in the following example:
exclude "reserved_for"="redo_log"
This technique allows you to share appropriately tagged disks among a set of
volumes of the same type. For example, if you specify the same confinement rule
when creating several redo log volumes in a storage pool, those volumes share
the disks that are reserved for that purpose.
