VCEM Profile Failover and Profile Moves White Paper

How HP selected the set of installed failover events
The collection of recommended events includes those events HP believes will be consistently
useful to customers. You may customize this collection or add additional collections for your
local installation.
HP used the following factors and rationale to select the recommended events:
• Exclude events that do not indicate a server hardware failure.
• Exclude events related to components that are usually configured redundantly. (For
example, the HP BladeSystem c7000 Enclosure accommodates redundant power supplies
and fans. Enclosure events for power and fan failures are reported to HP Systems Insight
Manager and immediate action should be taken to “hot-fix” failed components. In most
data centers timely replacement is completed without impacting service delivery.)
• Exclude events related to system components that are not needed to deliver services. It is
assumed that system configurations do not depend upon local storage for failover.
Therefore, related events will not impact service delivery capabilities.
• Exclude events that are not likely to be received by HP Systems Insight Manager because
the reporting system is not healthy enough to transmit them. These events include HBA
failures and most CPU and NIC failures.
The set of failover events installed with VCEM
The following recommended events are pre-configured in the VCEM Failover Events
collection. All of these events can be characterized as “pre-failure” events, meaning that a
failure has not yet occurred but should be expected at any time.

Using HP Systems Insight Manager action on events with failover
HP Systems Insight Manager has the ability to monitor SNMP traps and WBEM events.
These events can be used to notify you or to do more complex operations such as triggering
executables on the Central Management System or on remote systems. This section describes
how you can take advantage of this functionality to trigger VCEM profile failover.
VCEM provides ease-of-use enhancements for administrators to take advantage of this
functionality. Included are links to wizards, custom tool enabled CLIs, and collections of
