2. In the failover cluster snap-in, in the console tree, make sure Failover Cluster Management is selected and then,
under Management, click Validate a Configuration.
The Validate a Configuration wizard starts.
3. Follow the instructions for the wizard and run the tests.
Microsoft recommends that you run all available tests in the wizard.
NOTE Storage Spaces does not currently support Clustered RAID controllers.
Therefore, do not include the Validate Storage Spaces Persistent
Reservation storage test in the storage test suite. For additional
information, visit the Cluster in a Box Validation Kit for Windows Server
site on the Microsoft Windows Server TechCenter website.
4. When you arrive at the Summary page, click View Reports to view the results of the tests.
5. If any of the validation tests fails or results in a warning, correct the problems that were uncovered and run the
test again.
3.4 Creating the Cluster in Red Hat Enterprise Linux (RHEL)
The following subsections describe how to enable cluster support, create a two-node cluster and configure
NFS-clustered resources for a Red Hat operating system.
Note that the Syncro CS solution requires the Red Hat Enterprise Linux High Availability add-on for the dual-active HA
functionality to operate properly and ensure data integrity through fencing. Product information regarding the Red
Hat Enterprise Linux High Availability add-on can be found at
http://www.redhat.com/products/enterprise-linux-add-ons/high-availability/ .
3.4.1 Prerequisites for Cluster Setup
Before you create a cluster, perform the following tasks so that all of the necessary modules and settings are
pre-configured. Additional details regarding Red Hat High Availability Add-On configuration and management can be
