Enabling fast failover for disk groups in a Microsoft Failover Clustering environment
Enabling fast failover for SFW disk groups in a Microsoft Failover Clustering environment involves the following tasks:
To support the fast failover feature, a new attribute, FastFailOver, is added to the Volume Manager Disk Group (VMDg) resource. This attribute decides whether or not a disk group is enabled for fast failover. The FastFailOver attribute can take values of True or False. The value True indicates that the agent enables fast failover for the configured disk group. The default value False indicates that fast failover is disabled for the disk group.
Note: |
Apart from configuring SFW fast failover support for Microsoft Failover Clustering, the SFW Configuration Wizard for Microsoft Failover Cluster also prepares a cluster for Cluster Volume Manager (CVM) support. Therefore, it can also be used for configuring CVM in a Microsoft Failover Clustering environment. |
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 upgrade is required if you have upgraded SFW HA on the cluster nodes. Refer to the Veritas InfoScale Installation and Upgrade Guide for more information. |
Using the SFW Configuration Wizard for Microsoft Failover Cluster to configure fast failover
- From the Start menu (the Start screen on Windows 2012 operating systems), type Run, and then press Enter to open the Run dialog box.
In the Run dialog box, type scc, and then click OK to launch the Solutions Configuration Center (SCC).
- From the Solutions view in the SCC, click on SFW Configuration Wizard for Microsoft Failover Cluster to launch the wizard.
- The SFW Configuration Wizard for Microsoft Failover Cluster panel displays cluster and system (node) information and lets you configure or unconfigure systems for fast failover as described below.
Select one or more systems that are not yet configured and click Configure to configure fast failover support for the selected systems.
To unconfigure fast failover support, select one or more configured systems and click Unconfigure to unconfigure fast failover support for the selected systems.
- Click Done to exit the wizard.
To enable fast failover for SFW VMDg resources
- From the Start menu (the Start screen on Windows 2012 operating systems), click Administrative Tools.
Launch the Failover Cluster Manager snap-in by clicking Failover Cluster Manager.
- Right-click . Select . This creates a service group, for example, .
- Right-click the new service group and select from the context menu.
A new Volume Manager Disk Group (VMDg) resource is created with a default name.
- Right-click the VMDg resource and select .
Complete the following on the window:
Select the tab to change the default name of the to a name of your choice. Say, for example: VMDg1
-
Now select the tab and perform the following steps:
In the box enter the dynamic cluster disk group name created earlier in this document. Say, for example GuestDG1.
-
Edit the attribute value to .
Displayed default value is .
Note: |
To enable live migration, you must set the attribute to for all VMDg resources in a cluster. |
- Right-click the VMDg resource and select option from the center pane of the Failover Cluster Manager snap-in.
