Configuration
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.

4 Configuring 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. See
the Downloads and Drivers section for your library model.
Run a test backup to ensure that all components are properly
configured.

Configuring the Host System 5
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. Type “reset”.
4. At the OK prompt, type “probe-scsi-all”.
Run a test backup to ensure that all components are properly
configured.

6 Configuring the Host System
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 Some drivers have different names, depending on whether or
not they are listed in the output of an ioscan or in the system
file.

Configuring the Host System 7
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. Since
this driver is not dedicated for this particular device, it must be
manually installed. The following sections describe this process:
•Installing the pass-through driver (below)
•Creating a device file for the robotics controller (page 8)
•Verifying the installation (page 10)
Installing the
Pass-Through

the Robotics Controller. Otherwise, continue with the next
step.
5. From the Menu Bar, select Actions. Select Add Drivers to
Kernel, and press Return.
6. From the Menu Bar, select Actions. Select Create New
Kernel, and press Return.
7. A t t h e
Are you sure prompt, respond Yes . Press Return.
8. After the status messages, select OK. Press Return. The system
reboots.
Creating a
Device File for
the Robotics
Controller
1. Use the mknod command to create a device file to access the
robotics controller. The command syntax is:
/user/sbin/mknod /dev/scsi/<devfilename> c
<majornum> <minornum>
•<devfilename> is the user-defined name of the device file.
•<majornum> is the character major number from the lsdev
command.
•<minornum> is the minor number in the format 0xIITL00;
where II is the two-digit card instance number in
hexadecimal; Tis the target SCSI ID number; Lis the LUN
number, and 00 is reserved.

Configuring the Host System 9
2. Determine the value for <majornum> by executing the following
command for robotics attached to an HSC or PCI adapter:
lsdev -d sctl
The output resembles the following:
Determine the value for <minornum> 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).
For the HSC or PCI adapter, the ioscan output for the schgr
driver can differ in two ways, though either indicates successful
device file creation.
•If the schgr driver is configured on the system, this driver
appears to be associated with the library. The output would
resemble the following:
•If the schgr driver is not configured on the system, no driver
appears to be associated with the library. The ioscan output
line resembles:

10 Configuring the Host System
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. For example, if the device file name is /dev/
rmt/HPA1234, the command would be:
/usr/contrib/bin/scsi_io /dev/scsi/HPA1234
If the robotics is correctly configured, the following appears:
the thing claims to be: HP C7200-8000
NOTE HP C7200-8000 is used only as an example. The actual
ioscan output will reflect the product number and firmware
revision of the library you are configuring.

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. The
actual RUN MAPPER output reflects the product number of your
library.
1. Power on the library and host. Run ODE at the ISL prompt:
ISL>ODE
2. Identify the device path through RUN MAPPER:
ODE> RUN MAPPER

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> apath 10/4/4 id=HP28696A
io> apath 10/4/4.0 id=pseudo
io> apath 10/4/4.1 id=pseudo
io> apath 10/4/4.2 id=pseudo
io> apath 10/4/4.3 id=pseudo
io> apath 10/4/4.4 id=pseudo
5. Configure the robotics controller and the drives (the pass-thru
driver):
io> adev 30 id=HPA4669A path=10/4/4.0.0
io> adev 31 id=DLT8000 path=10/4/4.1.0
mode=autoreply
io> adev 32 id=DLT8000 path=10/4/4.2.0
mode=autoreply
io> adev 33 id=DLT8000 path=10/4/4.3.0
mode=autoreply
io> adev 34 id=DLT8000 path=10/4/4.4.0
mode=autoreply
6. Verify the bindings between PATH, LDEV number, ID, PMGR
(device drivers), and LMGR attributes for each device configured.

Configuring the Host System 13
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. Verify the binding for the robotics controller (the pass-thru
driver):
io> lpath 10/4/4.0.0
PATH: 10/4/4.0.0 LDEV: 30
ID: HPA4669A TYPE: MOSAR_AC
PMGR: MO_SCSI_PTHRU_DM PMGRPRI: 10
LMGR: LOGICAL_DEVICE_MANAGER MAXIOS: 0
Repeat this step for lpath 10/4/4.1, 4.2, 4.3, and 4.4.
d. Verify the binding for the tape drives (the differential tape dm):
io> lpath 10/4/4.1.0
PATH: 10/4/4.1.0 LDEV: 31
ID: DLT8000 TYPE: TAPE
PMGR: SCSI_TAPE2_DM PMGRPRI: 10
LMGR: LOGICAL_DEVICE_MANAGER MAXIOS:

14 Configuring the Host System
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

LDEV: 34 DEVNAME: OUTDEV: 0 MODE:
ID: DLT8000 RSIZE: 128 DEVTYPE: TAPE
PATH: 10/4/4.4.0 MPETYPE: 24 MPESUBTYPE: 8
CLASS: TAPE
7. Save the configuration changes as follows:
a. Hold the configuration changes:
io> hold
b. Exit the io section:
io> exit
c. If you have followed the local convention for backing up the
configuration file, keep the changes:
sysgen> keep
keeping to group CONFIG.SYS
Purge old configuration (yes/no)?y
CAUTION Check with the system administrator to ensure you
can keep the changes to the configuration file.
