Using the Device Configuration Wizard
The Device Configuration Wizard uses an intuitive graphical user interface to guide you through the device configuration process. The wizard probes your Enterprise and detects information about your nodes, devices, tape libraries, and connections.
The following is a sample session of the Device Configuration Wizard for illustrative purposes. This sample session sets up a SAN with three heterogeneous servers and one six-drive tape library, as depicted in the following diagram:
The wizard asks you to log into your Enterprise. Log into the master server as an administrator. After entering your credentials, click next.
The wizard displays all nodes in the Enterprise that can serve as device controller nodes.
Use the check boxes to select one or more controller nodes for which you want to install and configure devices.
Clicking the Options… button will display a dialogue box with a list of configurable scan options.
The following options can be adjusted:
Show all the nodes
There may be nodes on the Enterprise whose configuration options indicate they are not compatible with scanning. By default, these nodes are not displayed in the list of potential device controllers. Selecting this option will include those nodes in the list.
Concurrent Nodes to Scan
This setting affects how many nodes the wizard will communicate with concurrently while performing the scan. This can affect scan speed.
NDMP Port #
This setting allows you to set a port number for communicating with NDMP capable NAS nodes.
Check here to enable LTO Encryption Option
Clicking this check box will activate the Please Select pull-down menu, which you can use to enable/update or disable LTO hardware encryption functionality. The enable/update option is used to enable the encryption option for nodes that support this feature or to update the list of tape devices that the node can encrypt data to.
Clicking the Assign Peer Nodes button displays any other nodes that can communicate with devices in the SAN. (These are nodes that are not running one of the supported platforms listed at the beginning of this chapter).
When you are finished configuring options and/or selecting devices, click next.
At this point, the wizard scans the selected node(s) for SCSI devices.
When the nodes have been successfully scanned, “Done” appears in the status column, and the Next button becomes enabled. Click next to continue.
The wizard displays all unconfigured tape libraries that are accessible by the selected nodes. In this example, there is only one tape library, and it is accessible by both nodes. Select the tape library that corresponds to the server (controller node) that will control the media changer. You can either click anywhere in the entry’s row and then click the Add to Enterprise button (which becomes enabled once a selection is made), or you click the entry’s associated check box, which will advance you to the next step without the need to click Add to Enterprise
The wizard requests information about the tape library you selected.
Complete the active fields in the dialog:
Configure As SAN
This check box gives you the option to configure the device as a SAN. The check box appears if the device is seen by only one node. If multiple nodes see the device, it is automatically configured as a SAN and the check box does not appear.
Tape Library Name
Enter a name (up to 14 alphanumeric characters) for the tape library (for example, DEC_TL810). No two tape libraries in the Enterprise can have the same name.
Tape Library Type
Select the tape library type (for example, DEC_TL810) from the pull-down menu. If your tape library type is not shown, select the type that most closely matches yours.
Controller ID
The Device Configuration Wizard generates a media changer device file and installs it on your controller node. The name of that file, assigned by DPX, is displayed in this field.
Data Slots
From the pull-down menu, select the starting and ending slot numbers to use for media volumes. Note that slot numbers start at zero (0). Thus, the first slot is slot number 0, and the final slot is slot number (n-1), where n is the number of slots in your tape library.
Cleaning Slots
From the pull-down menu, select the starting and ending slot numbers to use for cleaning tapes. To configure a single cleaning slot (typical setup), enter the slot number twice. If no cleaning slots exist, leave these fields blank.
Device Type
Select a device type (for example, LTO) from the pull-down menu. All devices in a tape library must be the same type.
Cleaning Threshold
Enter the number of times a drive can be used before it is cleaned.
Comment
Optionally enter an alphanumeric string of up to 48 characters.
When you have filled in all the required information, click Next.
The wizard displays a list of devices attached to the newly added tape library.
If you need to change the device names, you can do so on this screen. Click inside the device name field and enter a new one.
When you are finished changing device names, click Next.
The wizard indicates that the tape library has been added by placing a check mark in the box in the leftmost column on the New Tape Libraries window. If you have additional tape libraries to add to the Enterprise (in this case we do not), repeat steps 3 through 5 for each.
Note. For a SAN, the tape library needs to be added only once.
Click Next when you are finished adding tape libraries.
The wizard shows the devices that were added, as well as other detected devices that were not part of a configurable tape library.
You can use this window to add additional devices as well as to remove any of the devices that you added in previous steps.
To add additional listed devices, select a device and click Add to Enterprise, assign the device to a tape library or device pool, then specify a device name.
To remove a device you have already added, select the device and click Remove from Enterprise.
Note. If you encounter an error, click View Log. A log file, which can be used for troubleshooting, is displayed. Save the log file by clicking Save….
Click Exit to exit the Device Configuration Wizard.
When you later log into the management console and navigate to the Configure Devices window, you can open the device clusters to view all the devices and device paths for a given tape drive.
You can edit the information for any of these devices in the management console under Configure Devices.
