Overview

Once you’ve cabled and configured the storage media, you must verify that the drivers are ready and working properly on the computer in which you wish to install the MediaAgent. This is performed before installing the MediaAgent software. The following steps, although not conclusive, should help you to identify most of the common configuration problems.

Ensure that all SCSI adapter and tape device drivers are installed.

Windows

The following steps explain common configuration problems for Windows 2000, Windows 2003 Server, and Windows 2008 Server.  

You can access the Computer Management window using the following options from the Start menu – Programs, Administrative Tools, Computer Management.
  1. In the Computer Management window, make sure the attached media changer, tape or optical drives for the library are listed.

  2. Expand tape or disk drives and select each drive, right click and select Properties to verify that the drive information is correct. Check the Device Status and ensure that the device is working properly.
    If drives are not listed, detect the device and install the appropriate driver. For more information on this task, refer to the user manual provided by the manufacturer of your library and drive.

For devices using the iSCSI and Storport drivers make sure that the medium changer for the library is enabled in the Windows Computer Management window. For all other drivers we recommend that the media changer is disabled in the Windows Computer Management window.

  1. From the Computer Management window select Device Manager in the left window panel and expand Medium Changers in the right window panel.
  2. Right-click the library with the media changer and select Enable or Disable as appropriate.

If you are starting the computer for the first time after installing the MediaAgent, ensure that the Removable Storage Management (RSM) is disabled.

  1. Do one of the following:

Solaris

  1. Ensure that the appropriate drivers for the SCSI/HBA/FC card are installed and working properly.
  2. Ensure that all the devices (libraries and drives) are connected properly.

HP-UX

HP-UX MediaAgent requires the kernel modules stape, sctl and schgr to be loaded, in order to use tape libraries. Install these kernel modules using the following steps:

  1. At the Unix prompt type sam.
  2. In the System Administration Manager dialog, select Kernel Configuration and press <Return>.
  3. In the Kernel configuration dialog, select Drivers and press <Return>.
  4. Select stape.
  5. From the ACTION menu choose add drivers to kernel.
  6. Repeat steps 4 and 5 to load sctl and schgr kernel modules.
  7. Choose Process New Kernel.
  8. At the prompt select the option to reboot the system.

AIX

In AIX MediaAgents, you can view a list of SCSI devices and tape drives using either the smit or lsdev command. You can also use the wsm tool, which is a graphical administrative tool.

Using smit

  1. At the Unix prompt type smit.

    Viewing SCSI Adapters

  2. In the System Management Interface Tool dialog box, select Devices, SCSI Adapter and then List All SCSI Adapters.

    A list of all SCSI adapters available in the system are displayed.

    Viewing Tape Drives  

  3. In the System Management Interface Tool dialog box, select Devices, Tape Drives and then List All Defined Tape Drives. A list of all the tape drives attached to the system are displayed.

Using lsdev

  1. At the Unix prompt type:

    lsparent -C -k scsi

    A list of all SCSI adapters available in the system are displayed.

  2. At the Unix prompt type lsdev -C -c tape.

    A list of all the tape drives attached to the system are displayed.

Tru64

  1. Ensure that all the devices (libraries and drives) are connected properly.
  2. Use the following command to list the devices attached to the system:

    hwmgr -show scsi

  3. If you do not see the devices, use the following command to auto-detect the devices: 

    hwmgr -scan scsi

NetWare

  1. Ensure that all the devices (libraries and drives) are connected properly.
  2. Use the following command to list the devices attached to the system:

    list devices

    A list of devices connected to the NetWare server are displayed.

    If you do not see the devices, use the following command to detect the devices:

    nwconfig

    If you have a Qlogic card and use the /IGNCFG command to see the devices edit the load command for the Qlogic HAM with /IGNCFG in Startup.ncf file.

    It is recommended that you unload any Custom Device modules (CDMs) that may be loaded, before configuring the libraries. (e.g., nwtape.cdm)

    Use the list storage adapters command to determine the CDMs that are loaded and then use the unload command (e.g., unload nwtape.cdm)  to unload these modules.

    It is also recommended that the list of unload commands are included in the autoexec.ncf, to prevent these modules from being loaded after subsequent reboots.

Linux

In Linux MediaAgents, you can view a list of SCSI devices and tape drives using either the Hardware Browser or Terminal to view the attached devices. Using the Hardware Browser

  1. Ensure that all the devices (libraries and drives) are connected properly.
  2. Install the necessary drivers for the SCSI devices.
    For example, using GNOME, you can access the Hardware Browser using the following options: From the Start menu – System, Hardware Browser.
  3. On a Linux computer you can view the libraries and drives from the Hardware Browser.
  4. Click on the SCSI devices to view a list of SCSI adapters available in the computer.

  5. Click on Tape Drives to view a list of tape drives attached to the computer.

Using the Terminal

  1. Ensure that all the devices (libraries and drives) are connected properly.
  2. Install the necessary drivers for the SCSI devices.
  3. Navigate to the following folder in the Terminal window:

    /proc/scsi

    The location of this file may vary in the various Linux Kernel versions.
  4. Open the following file:

    scsi

  5. The SCSI devices attached to the computer should be listed.
