There are a few requirements when restoring to a SQL cluster.
1. You must first (re)start the SQL server/services in single instance mode. This is some kind of maintenance mode. Basically you have to first un-cluster the cluster.
1a. Now you should only have a single active SQL server, let's call it NodeA. This is where you should run the SQL restore procedures. You cannot restore SQL from within the master or media servers. You have to do it from within the active SQL server NodeA.
2. Since you backed up the SQL cluster using a virtual name, NodeA cannot restore the DBs because Nbu treats the virtual name and NodeA as unrelated entities.
To solve this problem, one solution is to create the following touch file:
install_path\NetBackup\db\altnames\No.Restrictions
3. Now that the prerequisites are all set, you have to follow the steps in the Nbu SQL admin guide under "Redirecting a restore to a different host". It is considered a redirect restore because, as stated previously, the SQL virtual name and NodeA are considered unrelated by Netbackup.
You will find details to all 3 of the above steps in the Nbu SQL admin guide.
