Enabling fast failover for disk groups (optional)
For service groups that contain many disk groups, you can greatly reduce failover time by implementing the SFW fast failover feature for disk groups.
More information is available about fast failover benefits and requirements.
See Considerations for a fast failover configuration.
For implementing the fast failover feature, VCS provides a new attribute, FastFailOver, for the Volume Manager Diskgroup (VMDg) resource. This attribute determines whether or not a disk group is enabled for fast failover.
Note:
The disk group version must be 60 or later for fast failover to work. To verify the disk group version, from the VEA console, right-click the disk group and click
. Disk group version upgrade is required after upgrading SFW HA on the cluster nodes. Refer to the Arctera InfoScale™ Installation and Upgrade Guide for more information.You can enable fast failover for all the VMDg resources while configuring the service group using the configuration wizard. The service group configuration wizard provides a checkbox to enable fast failover.
Perform these steps if you did not enable fast failover using the wizard or if you have configured the service group manually.
The following procedure describes how to enable the FastFailOver attribute using the VCS Java Console.
To enable the FastFailover attribute for a VMDg resource
- In Cluster Manager (Java Console), select a service group with a VMDg resource configured for it.
Select the Properties tab from the right pane.
- Scroll down to choose the FastFailOver attribute and click to edit the attribute value.
- In the Edit Attribute dialog box, check the FastFailOver check box and then click OK.
- Repeat these steps for every VMDg resource for which you want to enable fast failover.
