Tape Library Installation on HP-UX

This procedure explains how to install a tape library for an HP-UX controller node. DPX supports HP-UX 11 and 10.x.

The following is the procedure for tape library installation on HP-UX:

  1. On your controller node, run detect -i at the command prompt. This places the device file in the dev directory, and binds the HP pass-through driver to the media changer.

The following is sample output from detect -i:

The media changer’s device file is identified as a media changer device under the Device Type column header. If you do not see the media changer device in the output from detect -i, proceed to Step 2 below.

If you do see the media changer device in the display from detect -i, the installation of the tape library media changer device file is completed. To test the installation, proceed to Chapter 36: Tape Library Verification. Use the media changer device file name (for example, /dev/c2t1d3_sa) as the argument for JItest.

  1. If you do not see the media changer device in the output from detect -i:

    1. Check that your tape library is properly connected, then redo Step 1.

    2. If your controller node is running HP-UX 11 or HP-UX 10.20 and your tape library is properly connected, contact Catalogic Software Data Protection Technical Support. If your controller node is running an earlier version of HP-UX, perform one of the following procedures:

      Before starting either of these installation procedures, ensure that the SCSI pass-through driver (spt or sctl) and default tape driver (stape) can be checked/added. Also, make sure you have the schgr driver loaded on the operating system. This is done by using the System Administration Manager (SAM). See the kernel configuration > drivers > action menu in SAM.

Additional information regarding the installation procedures below can be found in the man page of scsi_pt and scsi_ctl.
