4. You must validate that your target is compatible with your source and can stand-in if the source
fails. Click Validate configuration. You can also select Actions, Validate. The Validation tab
at the bottom of Full-Server Failover Manager updates to display the validation check. Errors are
designated by a white X inside a red circle. Warnings are designated by a black exclamation
point (!) inside a yellow triangle. A successful validation is designated by a white checkmark
inside a green circle.
Double-click on any of the validation items to see details. You must correct any errors before you
can enable protection. Depending on the error, you may be able to click Fix or Fix All and let
Full-Server Failover correct the problem for you. You can also select Actions, Fix Validation
Issues or Actions, Fix All Validation Issues. For those errors that Full-Server Failover cannot
correct automatically, you will need to modify the target to correct the error, or you can select a
different target. You must revalidate the selected servers until the validation check passes
without errors.
5. Once the validation check passes without errors, click Enable Protection to begin monitoring.
You can also select Actions, Enable Protection.
NOTE: If you have a Full-Server Failover connection established, do not create any Storage
Mirroring connections from the Full-Server Failover source or target.
If you are using a cluster, you must manually alter the disk signature before or after
failover. See the Microsoft Knowledge Base article 280425 at
http://support.microsoft.com/kb/280425 for details on how to change the disk signature.
You can automate the disk signature alteration as part of failover using the pre- or
post-failover scripts. See Configuring optional settings on page 5-4 for instructions on
the failover scripts.
