Recovery operations fail when recovering data using the hotadd transport mode. The following message appears in the Activity Log

Solution:

Recovery operations fail using the hotadd transport mode when the disk settings are not configured properly.

To configure the disk, do the following:

  1. Log in to the backup proxy system using an account with administrative privileges.
  2. Open Windows Command Line.
  3. From the command line, type the following command
    
    diskpart
    
    

    Press Enter.

  4. Type SAN and then press Enter.

    The current SAN policy displays.

  5. Type the following command:
    
    SAN POLICY = OnlineAll
    
    

    Press Enter.
