4 . If this is a validation for what will be a new cluster, you must add all the servers
that will become members of the new cluster by entering their names or by
clicking Browse and selecting them. Remember that all members of a cluster must
be part of the same domain. As each name is entered, a check will be performed on
the node. Once all machines are added to the server list, click Next.
5 . The tests to be performed can be selected. For a new cluster, you should always
leave the default of Run All Tests selected. Even for a validation of an existing
cluster, it’s a good idea to run all tests. However, you can select the Run Only Tests
I Select option to expose an additional configuration page that allows you to select
the specific tests that you wish to run (shown in Figure 7.22, which I’ve edited to
show all the Hyper-V options in detail). If the Hyper-V role is not installed, then
the Hyper-V tests are not run. Notice the level of depth the cluster tests perform on
Hyper-V. Click Next.
6 . If you selected to perform storage checks on an existing cluster, you can select
which storage will be validated. Storage validation involves testing arbitration and
moving tested storage units, which would shut down any roles using the storage,
so do not test any storage that is running roles, such as virtual machines. I like to
have a small LUN that I don't use that I keep for storage validations. If this is a
validation for what will be a new cluster, then you are not prompted for which
storage to validate. Click Next.
7 . A confirmation is shown of the tests that will be performed. Click Next to start the
validation.8 . The validation can take some time, especially if a large amount of storage is
attached, but the progress of the test and its success/failure is shown (see Figure
7.23).
9 . Once the validation is complete, a summary is displayed, showing the
success/failure of each test. You can click a View Report button to see the report
results and details of each test in a web browser. If the validation is for servers not
yet in a cluster, a check box is automatically selected (Create The Cluster Now
Using The Validated Nodes), which means that when you click Finish, the Create
Cluster Wizard will launch with the servers automatically populated. Click Finish
to exit the validation wizard.
