VCEM Profile Failover and Profile Moves White Paper

VCEM profile failover may also be initiated using the CLI. Select one of the following

command parameters options:

• Using the failed system’s host name

vcem –failover –host hostname

• Using the failed system’s IP address

vcem –failover –ip ip_address

• Using the failed system’s enclosure and bay number

vcem –failover –bay enclosure_name:bay_number

Once the command has been executed, a job ID number is displayed and can be used for

input to another VCEM CLI to monitor the status of the failover. An example command

showing how to display job details follows

vcem –list –details –job job_id_number

Initiating Failover using HP SIM Automatic Event Handling

This section describes how to configure and use HP SIM Automatic Event Handling to

automatically initiate failover and also for user notification.

Concepts

To initiate failover, configure the following items for Automatic Event Handling:

• Select events that you want to use to trigger failover. HP recommends a set of events for

you to consider below. See

The set of failover events installed with VCEM

for more

information. You may use these events or select your own. The selected events are

automatically placed into an HP Systems Insight Manager event collection.

• Create an “action-on-event” task in HP Systems Insight Manager. In creating this task, the

failover event collection is applied to a collection of managed systems. One or more

actions are configured to execute whenever any event in the collection occurs. These

actions include e-mail notification and execution of a custom tool. VCEM provides two

custom tools to initiate failover.

o VCEM Profile Failover by Hostname

o Profile Failover by IP address

These custom tools are used as the argument to the VCEM failover CLI command. One of

these custom tools is selected and configured with action-on-event.

This procedure for configuring Automatic Event Handling is described in detail below.

The following figure depicts how the automatic failover initiation works once configured.
