Creating the device files – HP Ultrium Tape Drive User Manual

Page 14

HP-UX Systems

For an HP Ultrium drive, execute the following:

% /sbin/ioscan -f | grep "Ultrium"

The new lines should look similar to the following, where the

in the

field represents the

instance of the SCSI tape driver, not the SCSI ID:

tape 4 2/0/1.5.0 stape CLAIMED DEVICE HP Ultrium 3-SCSI

NOTE:

If you are installing the drive onto a Storage Area Network (SAN), the fibre channel/

SCSI bridge will also appear in the list of attached devices.

If you cannot find the Ultrium drive, this may be because the kernel does not contain the

correct driver. Use the System Administration Manager (

sam

) to add

stape

to the kernel:

To add

stape

to the kernel using

sam

% sam

Select the following:

Kernel Configuration

Drivers

Highlight the

stape

driver. If the driver has not been added to the kernel, both Current State

and Pending State will read “Out”.

Select the following:

Actions

Add Driver to Kernel

The Pending State will now read “In”.

To add the new driver to the kernel, select:

Actions

Create a New Kernel

The

stape

driver will now be added to the kernel and then the system will reboot.

Creating the Device Files

Once you have verified the tape drive connection, you will need to create the appropriate

device files for the drive. Normally, you would have rebooted your system after attaching the

tape drive, and this process runs

insf

. However, if you have not rebooted your system since

attaching the drive, you can create device files by one of two ways, either through the System

Administration Manager (

sam

), or by executing the

mksf

command.

To add device files using

sam

This is the recommended and simplest way to create device files.
