With the proper setup in Robot SAVE, you can run restricted state TCP/IP via the RBSRSURDY command. This allows the systems that are Data Center Participants (DCPs) to share tape volume information, with each other and with the Data Center Management System (DCMS), while in restricted state.

Before You Begin

You must complete the setup in the section below, and all of the following conditions must be met, in order for restricted state TCP/IP to become active for tape volume file sharing during restricted state.

  • The systems that will run restricted state TCP/IP cannot be standalone systems or a DCMS; they must be DCPs.

  • The participating DCPs and the DCMS must be set up in Robot NETWORK with valid IP addresses.

  • The DCMS cannot be in restricted state while the DCPs are in restricted state, because the DCMS cannot share data while it’s in restricted state.

The steps in the following section will help you ready your systems for restricted state TCP/IP.

Setting Up Restricted State TCP/IP

Setting up your system to run in restricted state TCP/IP is a three-step process: specifying the user ID for the restricted state TCP/IP, setting QRETSVRSEC to a specific value, and adding server authorization for the DCMS. All three of these steps must be completed on each of the DCPs that you want to share tape volume information during restricted state. After you have all the DCPs set up, you can go to the last section below, which is on testing the validity of your setup.

Step 1: Specify the user profile for restricted state TCP/IP

You must set a single user profile for the restricted state TCP/IP. Some things to keep in mind:

  • The user profile you set for restricted state TCP/IP must be the same one that’s running the RBSRSURDY command. Note: The backup will still run if the two profiles don’t match, but restricted state TCP/IP will not be initiated.

  • We recommend that you use the same user profile in this procedure on all of the DCPs that will be sharing information while in restricted state.

  • Do not leave the UserID field blank on RBS900 as that will prevent restricted state TCP/IP from being initiated. Note: The backup will still run if the UserID field is left blank, but restricted state TCP/IP will not be initiated.

Follow these steps to specify the user profile for restricted state TCP/IP:

  1. Run the following commands to add the appropriate Robot SAVE libraries to the library list:

    ADDLIBLE RBSPGMLIB

    ADDLIBLE RBSDTALIB

  2. Run the following command to open the Robot SAVE Defaults Setup panel:

    CALL RBS900

  3. Enter a user profile in the UserID field under Restricted State TCP/IP (you will have to page down several times to get to the correct panel).

  4. Press F3 to save your changes.

Step 2: Set the value for QRETSVRSEC

Before creating the server authorization entry in the next section (Step 3), all systems that are sharing information in the data center (all the DCPs) must be set to retain the server security data. Note: You must make this change on all the DCPs even if you’re on a non-secured system and aren’t using server authorization entries.

To retain server security data:

  1. Run the following command:

    WRKSYSVAL QRETSVRSEC

  2. Enter option 2 and press Enter.

  3. Enter 1 and press Enter to retain the server security data.

Step 3: Add server authorization entry for the DCMS

A server authorization entry is required for the user profile that you set up for restricted state TCP/IP in Step 1 above.

Follow these steps to add the server authorization entry:

  1. Run the following command to see if a server authorization entry already exists:

    DSPSVRAUTE USRPRF(rs_user)

    where:

    rs_user is the user profile set for restricted state TCP/IP (the user profile you entered in the UserID field on the RBS900 panel).

  2. If a QDDMSERVER entry already exists, skip this step.

    If the entry doesn’t exist, run the following command to create it:

    ADDSVRAUTE USRPRF(rs_user) SERVER(QDDMSERVER) USRID(rs_user) PASSWORD(user_pwd)

    where:

    rs_user is the user profile set for restricted state TCP/IP (the user profile you entered in the UserID field on the RBS900 panel).

    user_pwd is the password for the rs_user.

    Note: The SERVER parameter, QDDMSERVER, must be upper case.

Testing Your Setup

After you’ve finished setting up your system to run restricted state TCP/IP, you should test your setup. Note: You must run this test from the system console.

  • From a command line, run the following command to test the validity of your setup:

    RBSRSUTCP

When you run this command, it checks to see if all of the criteria for running in restricted state TCP/IP have been met and reports any problems in the job log. It also creates temporary DDM files mapped to the DCMS to confirm that the setup was done correctly.
