•
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 through the VCEM CLI, you must have HP SIM administrator privileges.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.
Single-density server bays are specified by their number. Double-density server bays must be specified with
the bay number followed by the A or B letter such as 12A or 12B.
For more information about CLI usage in VCEM, see the "Command Line Interface 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. Click VC Profile Failover. The Virtual Connect Enterprise Manager is executing the
request
message appears.
3. 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 also provides two custom tools to facilitate automated
VC Profile Failover.
To use automatic event handling in VCEM, 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 HP SIM reside.
The VCEM custom tools enable an administrator to initiate a VC Profile Failover using automatic event
handling. Any administrator with full permissions within HP SIM or VCEM can perform VC Profile Failover
operations. The VCEM custom tools can be deleted from the HP SIM or VCEM installation with no impact
to other operations.
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.
