HP Serviceguard Version A.11.20 Release Notes, August 2011

volumes managed by HP-UX Logical Volume Manager (LVM), because a physical volume failure
is not always a critical failure that triggers failover (for example, the failure of a mirrored volume
is not considered critical).
For this reason, it can be very difficult to determine which physical disks must be monitored to
ensure that a logical volume is functioning properly. The HP Serviceguard Volume Monitor provides
a means for effective and persistent monitoring of storage volumes.
You can use this monitor as an alternative to using Event Monitoring Service (EMS) resource
dependencies to monitor LVM storage. EMS does not currently provide a monitor for VxVM volumes.
IMPORTANT:
• The LVM monitoring capability (cmvolmond) for Serviceguard A.11.20 is supported from the
September 2010 patch (PHSS_41225) and later.
• The VxVM monitoring capability (cmvxserviced) was first introduced in a patch to A.11.18,
and is still supported.
• cmvolmond replaces cmvxserviced, combining the VxVM monitoring capabilities of
cmvxserviced with the new capabilities needed to support LVM monitoring.
Although cmvxserviced will still work in A.11.20, HP recommends you use cmvolmond
instead.
For more information, see “About the Volume Monitor” in chapter 4 of Managing Serviceguard,

Serviceguard Manager
HP Serviceguard Manager B.03.20 is a web-based, HP System Management Homepage (HP
SMH) tool, that replaces the functionality of the earlier Serviceguard management tools. Serviceguard
Manager allows you to monitor, administer and configure a Serviceguard cluster from any system
with a supported web browser.
Serviceguard Manager does not require additional software installation. Instead, using your
browser, you log into an HP Systems Management Homepage (SMH) and access the HP
Serviceguard Manager tool, as well as other system management tools.
The HP Serviceguard Manager Main Page provides you with a summary of the health of the cluster
including the status of each node and its packages.
DSAU Integration
HP Serviceguard Manager uses Distributed Systems Administration Utilities (DSAU) to display
consolidated cluster log (syslog) and consolidated package logs.
You can find more information on DSAU in the Distributed Systems Administration Utilities User’s
Guide, at the address given under “Documents for This Version” (page 33).
NOTE: DSAU does not support a local log consolidation server in a cross-subnet cluster. Instead,
you can setup a remote log consolidation server on the Quorum Server node or cluster.
Native Language Support
HP Serviceguard Manager Version B.03.20 is available in the following languages:
• Japanese
• Simplified Chinese
• Korean
• Traditional Chinese
• Standard French
