Bold items are resource instances that can be monitored. Bold italic
variables represent specific instances of volume groups, devices, and
logical volumes on the system.
Physical Volume Summary
The pv_summary is the summary status of all physical volumes in a
volume group. This status is based on the compiled results of SCSI
inquiries to all physical volumes in a volume group.
If you have configured physical volumes as package dependencies in
ServiceGuard, this resource is used to trigger package failover. Refer the
manual Using the Event Monitoring Service (HP Part Number
B7612-90015) for information on configuring ServiceGuard package
dependencies. If you are using the disk monitor with ServiceGuard, it is
important that you configure physical volume groups (PVGs) to give you
the most accurate pv_summary for ServiceGuard package failover.
