Introduction This white paper explains the integration of ACSLS-controlled StorageTek libraries with HP Data Protector. The whitepaper contains details of installation and configuration of the ACSLS Server, installation and configuration of Data Protector with the ACSLS library, and enabling ACSLS through firewall. After reading this paper you will be able to set up an ACSLS library, configure it to be used in Data Protector, and enable ACSLS to be used through a firewall.

Installing a Data Protector Cell Manager and clients For Data Protector Cell Manager and client installation, please follow the instructions provided in the HP Data Protector Installation and Licensing Guide. Installing an ACSLS server Automated Cartridge System Library Software (ACSLS) is Sun StorageTek’s server software that controls a Sun StorageTek tape library. An Automated Cartridge System (ACS) is a group of tape libraries connected through pass-through ports (PTPs).

5. Once you have the ok prompt, you need to set auto-boot env to false before probing for devices. More commands used in this prompt are listed in ‘Useful commands in Solaris’ in the Appendix on page 16. ok> setenv auto-boot? False ok> reset-all This command will reset all registers. 6. When the ok prompt appears, enter: ok> probe-scsi-all This displays the devices connected to the machine. Check whether the connected ACS STK library is recognized, and make a note of the target ID of the library.

11. Eject the CD. Note: ACSLS requires specific user IDs (acss, acssa and acsdb), however, these are created automatically at the time of installation of ACSLS. The home directories for the acsss, acssa, and acsdb user IDs reside under the ACSLS installation directory. The default installation directory for acsss is /export/home/ACSSS (referred to as $ACS_Home).

5. Respond y or n to the prompt for installing a SCSI device driver for SCSI libraries. Do you want to install the scsi device driver for SCSI libraries? (y or n): y Refer to the following example for the prompts you need to answer. Note: Sun StorageTek libraries attached behind supported Fibre host-bus adapters (HBAs) can be autosensed by ACSLS using the capabilities included in supported HBA software. Supported HBAs currently include all contemporary Emulex, Qlogic, and Sun-branded HBAs.

• From the boot process: Note: The STL L20 library is detected on tgt0, lun0. So the SCSI address of the STK L20 library is 0:0. • From the output of the command dmesg after the system is booted: Note: The STSK L20 Library is detected on tgt0, lun0. So the SCSI address of the STK L20 library is 0:0. Setting the ACSLS user password Optionally, you can set passwords to prevent a security exposure for the user IDs acsss, acssa, and acsdb.

Integrating Data Protector A. Installing a Media Agent You can either install the General Media Agent or the NDMP Media Agent on systems that will be physically connected to a backup drive in a StorageTek library and on the system that will access the library robotics through the ACSLS. Note: You need special licenses, depending on the size of the repository with media or the number of drives and slots used in the StorageTek library.

configuration, the LibAttach services are started automatically and will be started automatically after every reboot as well. Note: After you have installed the LibAttach service, check if the libattach\bin directory has been added to the system path automatically. If not, add it manually. For more information on the service, see the documentation that comes with the StorageTek library. On HP-UX and Solaris clients: Run the following command: /opt/omni/acs/ssi.

For Multipath devices, also select the client name, and add the path to the list of configured paths. 11. In the Busy drive handling list, select the action Data Protector should take if the drive is busy, and then click Next. 12. Specify the CAPs for the library and then click Add. Click Next. 13. In the Media Type list, select the appropriate media type for the device. 14. Click Finish to exit the wizard. You are prompted to configure a library drive.
PAGE 13
C. Configure a drive in the StorageTek ACS library device 1. In the Device Name text box, type the name of the drive. 2. In the Description text box, optionally type a description. 3. Optionally, select MultiPath device. 4. If the MultiPath device option is not selected, select the Media Agent client that will access the StorageTek robotics. 5. Click Next. 6. In the Data Drive text box, specify the SCSI address of the device.
PAGE 14
9. Click Advanced to set advanced options for the drive, such as Concurrency. Click OK. Click Next. 10. Optionally select Device may be used for restore, and/or Device may be used as source device for object copy, and specify a Device Tag. 11. Click Finish to exit the wizard.

Appendix Communicating with the ACSLM server The following commands are used to query the ACSLM about the CAP, volumes, drives, LSM and LMU, and to change them from offline to online. To get the status of the library from the ACSLS server, log in as acsss user. The following sequence shows the commands and their use. They are very basic. Using ACSSA commands on the ACS library server 1. Log on to the ACSLS Server # su - acsss 2. At the prompt, enter: $ cmd proc -ql 3. Wait for the ACSSA> prompt.
