Determining the SCSI ID Before you configure your system to support you Ultrium drive, you need to determine which SCSI ID as the Tape Device Type. This is reserved for Connor drives. If you use it with HP drives, you will get the error "Device to be configured does not match the physical device - HP C7401A | HP Ultrium Drives Technical Reference Manual V5.0 UNIX Configuration - Page 18
0, and click on the "DO" button or press [Enter] to apply the change. HP Ultrium drives will work with tar, cpio, backup, restore and dd. For systems other than is working properly.

To see the device drivers loaded currently - HP C7401A | HP Ultrium Drives Technical Reference Manual V5.0 UNIX Configuration - Page 22
with various Linux distributions. This should not be attempted by novice users. In order to determine if the drive has been detected by the tape driver at module load time, execute: dmesg | grep "st" This should find a number of lines.

edit the file /usr/src/linux/drivers/scsi/st_options.h and change the definition tell features of mt, you must tell the st driver that HP Ultrium drives use logical block addressing. You can do you use this approach, set the manufacturer parameter to HP and the model to "Ultrium 1-SCSI".

the SCSI ID Before you configure your system to support the HP Ultrium drive, you need to determine which SCSI ID to use. IDs must be unique for each device on attached to the SCSI bus. 1 Use the modinfo command to identify SCSI controller drivers installed on the system. - For FAS or ESP - HP C7401A | HP Ultrium Drives Technical Reference Manual V5.0 UNIX Configuration - Page 26
the following depending on which drive you are installing (there are 6 significant spaces between HP and Ultrium in line 2): for Solaris 2.7, 5.7 and 8: tape-config-list = "HP Ultrium", "HP Ultrium LTO 1", "HP_LTO_GEN_1", HP_LTO_GEN_1 = 1,0x36,0,0xd639,4,0x00,0x00,0x00,0x40,3; name="st" class - HP C7401A | HP Ultrium Drives Technical Reference Manual V5.0 UNIX Configuration - Page 27
you should confirm that your new tape drive is working properly. Chapter 6, "Verifying the Installation" provides instructions on backing up and restoring a sample file to test your installation.

Verifying the Installation Example: Suppose you are verifying the installation of an HP Ultrium tape drive on an HP-UX 10.X system. The procedure would be as follows.: 1 Change directory to root: % cd / 2 Back up /stand/vmunix to tape: % tar cvf /dev/rmt/0m ./ - HP C7401A | HP Ultrium Drives Technical Reference Manual V5.0 UNIX Configuration - Page 34

request, it and the target to which it wants to send information can transfer the data using one of three protocols (assuming both devices support them): asynchronous, synchronous, and wide. In asynchronous transfers, the target controls the flow of data. The initiator can only send data when the - HP C7401A | HP Ultrium Drives Technical Reference Manual V5.0 UNIX Configuration - Page 36
are transferred at the same time instead of a single byte. HP Ultrium drives support asynchronous, synchronous and narrow (8-bit) wide transfers. A mark slow application. It also avoids losing capacity through the flushing of partly written groups. On the other hand, infinite flush means that - HP C7401A | HP Ultrium Drives Technical Reference Manual V5.0 UNIX Configuration - Page 37
