NetBackup™ Deduplication Guide

Configuring the MSDP server to be used by an MVG server having different credentials

To add a disk volume of an MSDP server to an MVG volume, the MVG server must be able to use its default credentials to communicate with the MSDP server.

If the MSDP server is new, configure the MSDP server with the same credentials as the MVG server so that no additional configuration change is required on the MSDP server.

In many cases, especially if the MSDP server already exists, the credentials may be different. You must change the existing credentials or add new credentials on the MSDP server.

To configure the MSDP server to be used by MVG server if the passwords are different

  • Follow the MSDP existing instructions to change the password.

    How to reset the NetBackup authentication password on an MSDP disk pool.

To configure the MSDP server to be used by MVG server if the usernames are different

  1. Add an alias for the MSDP default user. The username and password of the alias user are the same as the MVG server credentials.

    Windows: <install_path>\pdde\spauser --a -u username [-p password] --owner admin - alias

    UNIX: /usr/openv/pdde/pdcr/bin/spauser -a -u username [-p password] --owner admin - alias

    Note:

    Adding an alias user is supported on NetBackup 10.5 or later. Do not run the command on an MSDP server with an earlier version.

  2. After you add an alias user, ensure that the alias user has the same data selection ID as the admin user. Run the following command:

    spauser -l

    For example,

    root@host ~ # spauser -l
    user 1 : msdp, data selection: 2, role: admin
    root@host ~ # spauser -a -u mvg-user --owner msdp --alias
    
    Password:
    Reenter Password:
    Please input password of super user [msdp]:
    
    Add user mvg-user successful !
    
    One MSDP user can only be used by one NBU domain! Do not use one same user in two or more NBU domains!
    root@host ~ # spauser -l
    user 1 : msdp, data selection: 2, role: admin
    user 2 : mvg-user, data selection: 2, role: admin
