Credentials |
The NDMP FSE server must use the same credentials as the OpenStorage storage server. Note: If the NDMP FSE host is the same host as the storage server, you must configure a DNS alias for the host. Then, use the alias name when you configure the NDMP credentials in NetBackup. The credentials must be the same as the credentials that you used for the storage server. NetBackup does not allow multiple credentials for the same host name. If you use the NDMP FSE server for other purposes, do not configure the credentials differently for that purpose. For example, if you also use the NDMP FSE server as a VTL with NetBackup, use the same credentials when you configure it with NetBackup. |
