Source and designated spare servers must be part of the same VC Domain.
•
Designated spare servers are powered off.
•
A spare server must be the same model as the source server.

Initiating VC Profile Failover through the VCEM CLI
You can initiate VC Profile Failover through the VCEM CLI or GUI.
To perform VC Profile Failover tasks using the CLI, you must have HP SIM administrative privileges.
To initiate VC Profile Failover using the CLI, enter C:\>VCEM -failover arguments, then enter the
appropriate argument as follows:
•
For a bay, enter -bay enclosure_name:bay_number
•
For a host, enter -host hostname
•
For an IP address, enter -ip IP_address
The host and IP address are valid arguments only when HP SIM runs on the same system as VCEM and full
server discovery is in operation in HP SIM.
For more information about CLI usage in VCEM, see the "Command Line Usage in Virtual Connect Enterprise
Manager" chapter in the
HP Virtual Connect Enterprise Manager User Guide.
Initiating VC Profile Failover through the VCEM GUI
1. Select an assigned profile with an acceptable spare server.
2. Select a bay with an assigned profile.
3. Click Profile Failover. The Virtual Connect Enterprise Manager is executing the
request
message appears.
4. Click OK to go to the Jobs page and monitor job progress.
Initiating VC Profile Failover using HP SIM Automatic Event Handling
The VCEM CLI can be used to automatically trigger VC Profile Failovers using HP SIM automatic event
handling. A collection of sample failover SNMP traps exists in the "Profile Failover Trigger Events” collection
under “VCEM Events” in the VCEM user interface. VCEM has also created two custom tools to facilitate
automated VC Profile Failover.
For automatic event handling to work, the following prerequisites must be met:
•
VCEM 6.0 has been installed as part of a HP SIM installation
•
DNS is properly configured in the environment
•
The Administrator account is usable on the system in which VCEM and SIM reside
The custom tools enable an administrator to initiate a VC Profile Failover. Any administrator that can run all
the tools on HP SIM or VCEM installation can perform a failover. The two custom tools can be deleted from
the HP SIM or VCEM installation with no impact other than the inability to configure automatic event handling.
IMPORTANT: Enabling automated failover actions can impact other operations in a data center. Before
using this feature, you must fully review potential implications to other system resources and data center
services, and ensure compatibility with any other applications designed to perform automatic event handling.
Unintended failover scan results in the loss of data and unnecessary system downtime.
To set up automated VC Profile Failover, complete the following steps:
