Configuration 1 Configuring the Host System Once the library is connected to a host, the Windows NT, Sun Solaris, HP-UX, and MPE/iX operating systems must be configured to recognize it. The procedures are different, depending on the host system.
Windows NT For Windows NT operating systems, perform the following operating system configurations: • Install the appropriate host bus adapter(s) • Install the corresponding drivers for the interface card(s) • Install the backup software To verify the installation, look for the library and drive after powering up the host. • Go into Settings -> Control Panel -> SCSI Adapter • You can also check your installation on Windows NT with HP diagnostic utilities available from www.hp.com/go/support.
Sun Solaris For Sun Solaris operating systems, perform the following operating system configurations: • Install the appropriate host bus adapter(s) • Install the corresponding drivers for the interface card(s) • Install the backup software To verify the installation, look for the library and drive after powering up the host. 1. Close all open applications and exit the Common Desktop Environment (CDE). 2. Type “init 0” at any prompt. This will shut down all processes, and take you to the OpenBoot PROM. 3.
HP-UX Hosts To enable communication between the host and tape library, appropriate drivers must be configured into the HP-UX kernel. Table 1 shows which drivers are necessary for each device. NOTE Table 1 Some drivers have different names, depending on whether or not they are listed in the output of an ioscan or in the system file.
If these drivers are already installed into the kernel, upon system boot they will automatically be associated with the hardware that they control. However, if drivers are missing, they must be installed. For more information on installing Fibre Channel drivers, refer to the HP Fibre Channel Mass Storage Adapter Service and User Manual (A3636-90002). A pass-through driver is used to manage the robotics controller.
NOTE HSC or PCI Pass-Through Driver Installation HP C7200-8000 is used only as an example. The actual ioscan output will reflect the product number of the library you are configuring. The following procedure assumes the use of a SAM terminal mode. In X-windows (GUI) mode, use the mouse button to select an option. 1. Run SAM. 2. Select Kernel Config, and press Return. 3. Select Drivers, and press Return. 4. Select sctl.
2. Determine the value for by executing the following command for robotics attached to an HSC or PCI adapter: lsdev -d sctl The output resembles the following: HSC or PCI Character Block Driver Class 203 -1 sctl ctl Determine the value for using the ioscan command. The applicable lines in the ioscan output are those that refer to the controller (contains the product name in the Description field) and to the adapter (contains the ext_bus in the Class field).
Verifying the Installation Confirm that the communications path to the robotics controller is functional: 1. Compile the SCSI I/O test program: cc /usr/contrib/src/scsi_io.c. -o/usr/contrib/ bin/scsi_io 2. Run the SCSI I/O test program, using the device file created during installation.
MPE/iX Hosts Requirements Libraries require additional Legato NetWorker Server software that runs on either an HP Intelligent Server or an NT Server. The HP 3000 must be a Legato Networker Storage Node. Configuring the Host The example below illustrates the steps needed to configure the library on MPE/iX. NOTE This example illustrates the driver binding, but is not optimized for performance since it shows the entire library on a single differential bus. The library ID of A4669A is used only as an example.
/4/4.1.0 /4/4.2.0 /4/4.3.0 /4/4.4.0 DLT8000 DLT8000 DLT8000 DLT8000 . . . . . . . . . . . . 3. Boot the system. At the MPE prompt, run sysgen and start the io section: sysgen SYSGEN version E . . . sysgen> io ** IO configurator commands ** 4. If not already configured, configure the differential card and the pseudo/target level of the SCSI path: io> io> io> io> io> io> apath apath apath apath apath apath 10/4/4 id=HP28696A 10/4/4.0 id=pseudo 10/4/4.1 id=pseudo 10/4/4.2 id=pseudo 10/4/4.
a. Verify the binding for the device adapter (the fw/differential dam): io> lpath 10/4/4.0.0 PATH: 10/4/4 LDEV: ID: HP28696A TYPE: DA PMGR: FWSCSI_DAM PMGRPRI: 6 LMGR: MAXIOS: 0 Repeat this step for lpath 10/4/4.1, 4.2, 4.3, and 4.4. b. Verify the binding for the targets (the transparent dm): io> lpath 10/4/4.0 PATH: 10/4/4.0 LDEV: ID: PSEUDO TYPE: DA PMGR: TRANSPARENT_MGR PMGRPRI: 6 LMGR: MAXIOS: 0 Repeat this step for lpath 10/4/4.1, 4.2, 4.3, and 4.4. c.
Repeat this step for lpath 10/4/4.1, 4.2, 4.3, and 4.4. e. To configure the Storage Node on the NetWorker server, verify the ldev specifications: io> Idev 30/34 LDEV: 30 DEVNAME: OUTDEV: 0 MODE: ID: HPA4669A RSIZE: 128 DEVTYPE: MOSAR_AC PATH: 10/4/4.0.0 MPETYPE: 24 MPESUBTYPE: 4 CLASS: LDEV: 31 DEVNAME: OUTDEV: 0 MODE: ID: DLT8000 RSIZE: 128 DEVTYPE: TAPE PATH: 10/4/4.1.0 MPETYPE: 24 MPESUBTYPE: 8 CLASS: TAPE ... LDEV: 34 DEVNAME: OUTDEV: 0 MODE: ID: DLT8000 RSIZE: 128 DEVTYPE: TAPE PATH: 10/4/4.4.
d. Exit sysgen and reboot according to local convention: sysgen> exit Verifying the Connection Additional information regarding the configuration and verification of libraries is provided in the Legato NetWorker Installation Guide (MPE/iX version) for the Networker Storage Node product.

Firmware Update Tool When started, the firmware update tool will examine the firmware revision of the current SCSI device, and then search the directory /var/tmp for firmware files that are compatible with the device. The internal headers of any firmware files present in this directory will be checked. If compatible files are found, it will select the most current version and pop up a dialog box asking if you want to update firmware immediately.
Sysdiag NOTE Version 5.5 and 6.0 are supported for the libraries, but use the STM tool for version 6.5 (see Support Tools Manager (STM) on page 19). Sysdiag is the MPE/iX support tool, and provides a consistent user interface for support of tape libraries, as well as many other types of peripheral devices. Sysdiag is a licensed-use tool, so a user must first know and enter a diagnostics password.
