Configuration Files

On the nodes that will be communicating with the AML/SDLC virtual tape libraries, you must create at least two files:

• One DAS environment file

• One or more tape library controller device files

Note. Do not confuse the DAS environment file (on the node) with the DAS configuration file (on the AML/SDLC) described earlier in this chapter.

A single node may serve as controller for up to eight AML/SDLC virtual tape libraries. You create the corresponding number of tape library controller device files.

To create the DAS environment file and the tape library controller device files, execute a script called acitest, which is in the folder bin/JB in the directory where was installed. The following shows the items in the AML Library Testing main menu:

From the menu, do the following:

1. Select option 1 to create the DAS environment file. Respond to the prompts. You provide the name of the AML/SDLC. This step creates a file called DasConf in bin/JB.

2. Select option 2 to create a tape library controller device file. Respond to the prompts. You provide the name and IP address of one AML/SDLC virtual tape library. You also provide access privileges and command options. Finally, you define the virtual tape library components such as device names, scratch pools, and media types. Most of these fields are obtained directly from the client entry on the DAS server configuration file described earlier in this chapter. This step creates a file called sync_saX, where X is an integer that you provide. The file sync_saX is in bin/JB.

3. Repeat step 2 for each AML/SDLC virtual tape library that will be controlled by this node.

4. Select option 4 to exit.

The acitest script also offers a utility menu (option 3). This enables you to perform initial testing of the AML/SDLC virtual tape library, allocate and release drives, and add volumes to the scratch pool.

Note. Before running backups to the AML/SDLC virtual library, you must allocate drives using the acitest utility menu (option 3).
