Assigning media servers to a storage server

When you configure a storage policy in NetBackup, you can choose a specific media server. This option restricts the media server you can use at the time the policy is run. However,NetBackup Flex Scale uses its own internal load-balancing mechanism to choose the media server. Ensure that you configure the storage units to use Any Available media server option to make the storage unit available to any of the media servers. An alert is generated for NetBackup Flex Scale if a specific media server is specified.
