Chapter 6 - Managing Jukeboxes

Adding and Configuring a Jukebox

To Add and Configure a Jukebox at the VINES Server

1. Select Backup/Restore from the Operator Menu.

2. Select Enterprise Backup and Restore.

3. Log in using your StreetTalk name and password.

4. Select Local Tape Operations.

5. Select Configure Jukebox.

6. Enter the letter of the jukebox device you are installing:

a. Compaq TurboDAT Autoloader/ARC-DiamondBack
b. EXB-210
c. HP
d. Quit

7. Enter a name for the jukebox. For convenience, use the same name as the model you selected.

8. Type in the device name (media drive pathname) of each jukebox you want to install, or press Enter for the default. Make a note of the name; you will need to refer to it later. If a jukebox has more than one tape device, the device pathnames must be listed in the same order as the devices are physically installed in the jukebox.

Note: If you are installing the EXB-210 tape device only, see the section titled "For EXB-210 Only."

9. Type in the slot numbers you want to use for backup, or press Enter for the default (maximum available) in this jukebox. If you enter the slot numbers, enter them as low_slot-high_slot. For example, to use slots 2 through 11, enter 2-11.

The jukebox is now installed and enabled. Test it to make sure it is in good working order, as follows:

10. At the VINES server, select Test Jukebox Functionality from the Local Tape Operations menu.

To use your installed device, you need to configure it through the Devices and Jukeboxes windows at the workstation. You can do this by following the steps in the next section, "To Configure a Jukebox from the Workstation."

For EXB-210 Only

For installations that support only an EXB-210 and no other tape device, slot and drive addressing is normally as follows:

Figure 6-1. Slot and drive Addressing for EXB-210

Figure 6-2. Drive Addressing for EXB-210 in a Rack-mount Configuration

Select the Reset Jukebox option at the VINES server console.
Take an inventory of the jukeboxe's contents as described in "To Take an Inventory" later in this chapter to correctly inventory the jukebox.

To Configure a Jukebox from the Workstation

1. Select Devices from the Server pulldown menu.

2. Enter the device pathname for the tape device that you entered at the server console (step 8) into the Name field.

Note: Be sure to create a device for each tape drive in your jukebox.

3. Select the appropriate Media type choice for the type of jukebox.

4. Click OK.

5. Close the Device window.

To Change the Available Slots

1. Select Jukeboxes from the Server pull-down menu.

Figure 6-3. Server Pull-down Menu

2. The Jukeboxes window appears, displaying the names of the jukeboxes known to the EBR server. These are the device names you entered when you first installed and enabled the jukebox module from the server console.

Figure 6-4. Jukeboxes Window

3. Select Edit from the Jukeboxes window. The Edit Jukeboxes window appears.

Note: The only changes you can make to a jukebox in the Edit window are to the Devices and Available slots fields.

Figure 6-5. Edit Jukeboxes Window

The Edit Jukeboxes window has the following fields:

Name: the name of the jukebox.
Model: the model of the jukebox.
Control port: the system pathname of the port that controls the jukebox loading mechanism. The loading mechanism loads and unloads the backup volumes into and out of the devices in the jukebox.
Devices: the system pathnames of the media devices (tape drives). These must correspond to the pathnames you entered in the main Devices window in step 3.
Available slots: which of the numbered slots available for holding backup volumes inside the jukebox will be used to satisfy mount requests. Typically, all will be used.

The Available slots field allows you to control exactly which slots in the jukebox hold backup volumes that are available to EBR for backing up files. Although EBR uses all of the volumes in the jukebox for recovers, you can control which volumes EBR will automatically select for backups by designating the available slots in the jukebox.

For example, you might designate slots 1 through 5 only for EBR backups. On the other hand, entering the single number "10," will direct EBR to slot "10" only for backups. In other words, designating certain slots makes those slots the ones from which the jukebox will retrieve writeable media.

4. Enter the pathname of each jukebox tape drive into the Devices field.

The tape device that you enter in the Edit Jukebox window Device field must first be created through the Devices window as described in steps 1 through 6.

5. Click on OK.

Operating the Jukebox

Starting a Labeling Session

To label backup volumes in the Jukebox

1. Select Label from the pulldown Media menu in the EBR Administrator window.

Note: If you are removing backup volumes from the jukebox, make sure you also unmount them by selecting the jukebox device from the Device window, and then selecting Unmount from the menu bar on the EBR Administrator' s window. This prevents you from accidentally relabeling these volumes when you reload the jukebox with new volumes.

Figure 6-6. Label Dialog Box

The Label window displays the following fields:

Device: name of the tape device in jukebox
Starting with: label on volume (numbered for first slot; for example, in the figure above, the label kady.005 is to be placed on the volume in slot 2). This field is empty if the volume is unlabled.

Note: You can only change this if you are labeling more than one slot.

First slot: number of the starting slot for labeling or inventory
Last slot: number of the Last slot for labeling or inventory
Pool: the pool selected for the volume to be labeled (for example, archive).

If you want to override the range of slots specified in the label window, enter slot numbers into the First slot and Last slot fields and click OK. The First slot and Last slot fields allow you to control the range of slots in the jukebox to be labeled or inventoried.

If you want to label a specific range of backup volumes, the Starting with name must match the label template format. If you label a single backup volume, you can use any name - it does not have to match the label template. The First and Last slots should be identical when labeling a single volume.

2. Click OK to start the labeling process. When a valid EBR label already exists on the media you are trying to label, a confirmation message appears.

Figure 6-7. Label Confirmation Message

The confirmation is important because it keeps you from accidentally relabeling the media. When a backup volume is relabeled, its contents under the previous label cannot be recovered.

You will also be prompted to "recycle" if the volume is still in the media index. See Chapter 3 for details.

3. When you confirm by clicking Ok, EBR starts labeling the media in the jukebox with the label displayed in the Starting with field until all the backup volumes in the range of selected slots are labeled.

Since it takes EBR some time to label the volumes in the jukebox, you may want to perform the labeling process at a time when you do not need to back up or recover any files.

To Mount Jukebox Backup Volumes Manually

1. Make sure the jukebox device is selected in the EBR Administrator window. This is especially important if you have the EBR server configured to use devices other than the jukebox.

Note: Although jukebox devices are identified by a "J" in their pathname in the devices window, it is still a good idea to place an adhesive label on the outside of a jukebox identifying its device pathnames, to remind you of which device pathnames belong to the jukebox. This practice is especially helpful when you are using devices other than those in the jukebox.

2. Select Mount (Read/Write) or Mount (Read Only) from the menu bar. The Mount window appears.

Figure 6-11. Mount Window

The Mount window displays the following fields:

Device: system pathname of the selected jukebox media device.

Slot: slot in which volume is stored.

Volume: label of volume stored in this slot.

Pool: pool to which the volume belongs.

% Used: percent capacity of the volume filled. This is informational only - it does not limit the amount of data EBR will store on a device. EBR will write data to a writeable backup volume until no more data can be written. For more information, see the Release Notice.

The currently selected backup volume name is highlighted.

To mount the selected backup volume in the jukebox, first select it from the list, then click on Ok.

Suggestions and Tips

Recycling versus Adding More Backup Volumes

If you need to keep the volumes for long-term storage, remove the full volumes and replace them with new media. Label the new volumes.
If you do not need the data on the full volumes, you can manually change to recyclable in the Volumes window and EBR will overwrite the data on the volumes with new backups, yet maintain the existing labels.

Note: The mode of a volume is automatically changed to recyclable when all of the save sets on the volume have passed the time period specified by the Retention policy of the client that generated them.

Taking Inventory of the Jukebox Contents

To Take an Inventory

1. Load the new backup volumes into the jukebox.

2. Select the jukebox device in the Devices window.

3. Select Label from the pulldown Media menu.

4. Click on Inventory .

Figure 6-12. Label Dialog Box

A message monitoring the progress of the inventory operation displays.

Figure 6-13. Inventory Progress Display

5. You may cancel the inventory operation after the current volume by clicking on Cancel in the Label window. Click on Cancel to close the window when the inventory is complete.
