Assigning Oracle Secure Backup Device Names on Windows

After you have established your administrative domain, you can configure any attached libraries and tape drives. Oracle Secure Backup supports both SCSI and Fibre Channel-connected devices, as well as NAS libraries and tape drives. Names for Oracle Secure Backup devices are user-defined.

In the following example, assume you have a combined administrative server and media server called BELLA with an attached library named obl0 and tape drive named obt0. The example uses obtool commands for device configuration, although you can also use the Oracle Secure Backup Web tool or Oracle Enterprise Manager to assign Oracle Secure Backup device names.


Note:

Disable any system software that scans and opens arbitrary SCSI targets before configuring Oracle Secure Backup tape devices. If Oracle Secure Backup has to contend with other system software (such as monitoring software) for access to tape libraries and drives, then unexpected behavior can result.

  1. If you are already logged on to Oracle Secure Backup, skip to Step 3.

    Otherwise, log on to Windows as the Administrator user or as a user that is a member of the Administrators group.

  2. To open Oracle Secure Backup, click the Start button and select Programs, Oracle Secure Backup, and Oracle Secure Backup Command Line Interface.

    The ob> prompt displays.

  3. Create an Oracle Secure Backup device object and assign it a user-defined name for the tape library. Specify options for the device type and media server. The following example assigns the name tc-lib to tape library obl0:

    ob> mkdev --type library --attach BELLA://./obl0 tc-lib
    
    
  4. Create an Oracle Secure Backup device object and assign it a user-defined name for the tape drive. The following example assigns the name tc-tape to tape drive obt0:

    ob> mkdev --type tape --library tc-lib --dte 1 --attach BELLA://./obt0 tc-tape
    
    

    Note:

    Oracle Secure Backup identifies each tape drive within a library by its data transfer element (DTE) number. You must specify a dte if library is specified. DTEs are numbered 1 through n.

  5. Check configuration information for both devices. For example:

    ob> lsdev -l
    
    

    In this example, the command displays the following output:

    tc-lib:
        Device type:            library
        Model:                  [none]

        Clean interval:         (not set)
        Clean using emptiest:   no
        UUID:                   ca196e5e-af6d-4978-9172-3dadb5d50ec7
        Attachment 1:
            Host:               BELLA
            Raw device:         //./obl0
    tc-tape:
        Device type:            tape
        Model:                  [none]
        In service:             yes
        Library:                tc-lib
        DTE:                    1
        Automount:              yes
        Error rate:             8
        Query frequency:        1207KB (1236976 bytes) (from driver)
        Debug mode:             no
        Blocking factor:        (default)
        Max blocking factor:    (default)
        Current tape:           2
        Use list:               all
        Drive usage:            none
        Cleaning required:      no
        UUID:                   d367a0dd-549c-4b99-9557-d9fc16d9d2c5
        Attachment 1:
            Host:               BELLA
            Raw device:         //./obt0
    

Note:

Device special files for tape libraries are named obln by default, where n is a number (the Oracle Secure Backup logical unit number, which on Windows is assigned automatically by the Oracle Secure Backup Windows device driver). For example, in the preceding output, the name of the device special file for the tape library (the value for the Raw device) is //./obl0. Note that the third character in the device special file name is a lower-case letter L, not the number 1.
