NetBackup status code: 1558
Message: Mirror retention is not allowed when target storage unit is not mirror capable.
Explanation: When you configured the replication operation in a storage lifecycle policy, you specified a mirror retention for a target storage unit that is not mirror-capable.
Recommended Action: If you used a nbstl command to configure the storage lifecycle policy, rerun the command after you do the following: Specify the appropriate retention type (other than mirror retention) for the replication operation corresponding to the storage unit that is non-mirror capable. Use the bpstulist -U command to view the storage unit properties. If the error occurs when you configure the storage lifecycle policy by using the GUI, submit a problem report and provide the appropriate logs.
