To support the fast failover feature, a new attribute, FastFailOver, is added to the VCS Volume Manager Disk group (VMDg) agent. This attribute decides whether or not a disk group is enabled for fast failover. The FastFailOver attribute can take values of 1 and 0. The value 1 indicates that the agent enables fast failover for the configured disk group. The default value 0 indicates that fast failover is disabled for the disk group.
Refer to the Cluster Server Bundled Agents Reference Guide for more information about the VMDg agent.
To enable the FastFailover attribute for a VMDg resource
Ensure that the cluster configuration is writeable.
Run the following command from the command prompt:
haconf -makerw
For each VMDg resource in a service group, run the following command from the command prompt:
hares -modify resource FastFailOver 1
Here, resource is the name of the VMDg resource.
Save and close the cluster configuration.
Run the following command from the command prompt:
haconf -dump
Refer to the Cluster Server Administrator's Guide for more information about managing resources and service groups.
