Adding a Tape Library
Before defining a tape library to DPX, you must install the tape library driver on the node to which the tape library is attached. Follow the instructions in Device Configuration Wizard.
A single tape library cannot contain both devices on a storage area network (SAN) and devices directly connected to a server.
To define a new tape library:
Go to Devices & Pools in the sidebar. Then select the Add device cluster button in the upper right corner to open the Add Device Cluster dialog.
Select Tape library as Type.
In the Tape Library Configuration section, provide the following parameters:
Name. Provide a name for the tape library. The name may only include alphanumeric characters (
a-z,A-Z,0-9), underscores (_) and hyphens (-). No other special characters are allowed. The name cannot be longer than 48 characters. No two device clusters within the Enterprise can have the same name.Storage Area Network toggle. For this flow, keep the toggle off. To add a SAN tape library, see Adding a SAN Tape Library.
Tape library type. Select your library’s manufacturer from the list, or select Generic.
Controller node. The controller node is a node that communicates with and controls the tape library media changer. The controller node is a special case of a device server. This is also the node where you have installed the tape library device driver. See Device Configuration Wizard. The controller node is connected to the tape library media changer either directly or over a SAN. Although this node must be running one of the operating systems specified in Manual Tape Library Installation, tape library devices (tape drives) can be attached to any controller node or NDMP node in your regular network or SAN.
Controller ID. Enter the complete path and name of the media changer device file on the controller node. The media changer device file contains the file handle for the tape library driver, e.g.
/dev/sg6. You will find it under Device ID for the Medium Changer Device device type. as per thedetect -qresults. See Device Configuration Wizard.Device type. Select a device type from the dropdown menu. All devices in a tape library must be the same type.
Using Slots. Enter the starting and ending slot numbers to use for media volumes. For example, entering
1and11means for DPX that slot numbers 1 through 11 are reserved for media volumes.Cleaning Slots. Enter the slot(s) used for the cleaning media. If there is only one cleaning slot, enter the slot number twice; for example,
0through0indicates that slot number 0 contains a cleaning media (the default value). If there is no cleaning slot, enter-1in each field.Description. Enter an optional description of up to 48 characters.
Click the Configure device button in the Devices Configuration section to configure tape drives within the tape library.
Specify the details for the first device.
The device name is auto-generated (and auto-updated) from the tape library name. You can edit it by hovering over the name. Note that the auto-update feature will stop once the user overrides the auto-generated name.
Device number. This field identifies the tape drive within the tape library. The first storage device is usually 0. This usually matches the last digit in the Device ID, but may differ depending on the tape library manufacturer.
There is a critical relationship between Device Number and Device ID for tape library devices. See Determining Device Number and Device ID.
Device ID. For devices controlled with a Linux machine, the path may be
/dev/nst0for the first device,/dev/nstfor the second one, and so on, as per thedetect -qresults. For devices controlled with a Windows machine, the device IDs are typically\\.\Tape0,\\.\Tape1and so on.Logical node name. Select the controller node for the drive. Typically, the controller node will be the same for the device cluster and all devices within the cluster.
Click Add.
Click Add another device and return to item 5 as necessary, until all detected devices are added.
Click Save. Your tape device cluster is now added to the DPX Master Server.
Now, proceed with adding a media pool for the tape device cluster.
Click Configure on the Function Tab bar of the window, then click Devices in the Configuration Operations section.
Open the Add Tape Library dialog in the right pane by doing one of the following:
Right-click the Enterprise name or icon to display the Enterprise context menu. The selection is indicated by the selection check box next to the Enterprise icon. Then select Add Tape Library.
In the left pane, select the Enterprise to which you want to add the tape library and do one of the following:
From the menu bar, select Device > Add Tape Library.
On the task panel, click Add Tape Library. The Add Tape Library dialog appears.
Complete the active fields in the Add Tape Library dialog:
Tape Library Name Enter a name (up to 48 alphanumeric characters) for the tape library. No two tape libraries in the Enterprise can have the same name.
Storage Area Network Specify whether devices in the tape library are connected to a Storage Area Network (SAN). A tape library cannot contain both devices on a SAN and devices directly connected to a server.
Tape Library Type Select a tape library type (for example, EXB210) from the pull-down menu. (For an ADIC SDLC tape library, select ADIC_AML.)
If you select either ACSLS for a StorageTek Automated Cartridge System (ACS), ADIC_AML for an AML Automated Storage Library, IBMATL for an IBM Magstar 3494 Tape Library (IBM 3494), the Using Slot and Cleaning Slot fields disappear and the Storage Area Network field is forced to No.
If you select ACSLS, the Controller ID field disappears and the ACS Number field appears. If you select IBMATL, the Category field appears in the dialog. If you select ADIC_AML, the pull-down menu on the Device Type field is disabled.
Controller Node The controller node is a node that communicates with and controls the tape library media changer. The controller node is a special case of a device server. This is also the node where you have installed the tape library device driver. See Device Configuration Wizard.
Select the node name of the controller node (for example, SALES_SERVER_1). The controller node is connected to the tape library media changer either directly or over a SAN.
Although this node must be running one of the operating systems specified in Manual Tape Library Installation, tape library devices (tape drives) can be attached to any controller node or NDMP node in your regular network or SAN.
Controller ID
Enter the complete path and name to the media changer device file on the controller node. The media changer device file contains the file handle for the tape library driver. For example, the media changer device file could be /dev/sync_sa/t0d0 for Sun or C:\backex\bin\JB\sync_sa0 for Windows. This file is created by DPX during tape library driver installation. See Device Configuration Wizard.
For IBM 3494, this is the logical name of the library control point that you specified when you first configured IBM 3494. This field does not appear if you choose ACSLS in the Tape Library Type field.
ACS Number This field only appears if you choose ACSLS in the Tape Library Type field. Enter the ACS Number. The ACS Number was specified in ACSLS when the ACS was first configured, and its valid range is 0-126. For more information on ACS, see Chapter 41: Using Oracle StorageTek Automated Cartridge System Library in the DPX 4.9 Reference Guide.
Category This field appears if you choose IBMATL in the Tape Library Type field.
Device Type Select a device type (for example, 4 mm) from the pull-down menu. All devices in a tape library must be the same type. If you chose ACSLS from the Tape Library Type pull-down menu, the Device Type DLT appears in this field.
Using a Slot
Enter the starting and ending slot numbers to use for media volumes. For example, entering 1 and 11 means for DPX that slot numbers 1 through 11 are reserved for media volumes.
Cleaning a Slot Enter the slot(s) used for the cleaning media. If there is only one cleaning slot, enter the slot number twice; for example, 0 through 0 indicates that slot number 0 contains a cleaning media (the default value). If there is no cleaning slot, enter -1 in each field.
Cleaning Threshold Enter the number of times a drive can be used before it is cleaned. An internal counter is incremented each time a media volume is inserted in the drive. For example, if you enter 50, a media volume can be inserted in the drive 50 times. Just before the next use, the cleaning media is inserted to clean the drive head. After the drive is cleaned, the counter is reset to 0.
Comment Enter an optional comment of up to 48 characters.
Select Add on the task menu at the top right of the right pane. If you are unable to see the task menu, resize the right pane. The new tape library name appears in the device resource tree in the left pane and is indicated by the selection check box. The add tape library dialog in the right pane becomes the edit tape library dialog for the new tape library.
