HP LTO Ultrium 5 tape drives UNIX, Linux and OpenVMS configuration guide (March 2010)

For a given SAS device the SAS address can be obtained from the Lun H/W Path. For example:
The lunpath hardware path for the above tape drive is “0/2/0/0/0/
0.0x500110a0013091b8.0x0”.
• The SAS bus ID is “0/2/0/0/0/0” (including all the numbers separated by “/”).
From the remaining “0x500110a0013091b8.0x0” portion:
• Tape drive SAS address (hexadecimal) = 0x500110a0013091b8
• Tape drive SCSI LUN = 0x0 (hexadecimal SCSI-3 64-bit LUN identifier)
Similarly, for a given FC device the FC bus ID, the World Wide Name (WWN) and the LUN ID can
be decoded from the Lun H/W Path. For example:
If the lunpath hardware path for a giventape drive is “0/4/1/0.0x50060b0000b7f3c8.0x0”.
• The FC bus ID is “0/4/1/0” (including all the numbers separated by “/”).
From the remaining “0x50060b0000b7f3c8.0x0” portion:
• Tape drive WWN (hexadecimal) = 0x50060b0000b7f3c8
• Tape drive SCSI LUN = 0x0 (hexadecimal SCSI-3 64-bit LUN identifier)
Adding stape/estape and eschgr/schgr (media changer driver)
to the kernel
For HP-UX 11i v2
If your tape drive or media changer does not appear in ioscan listing or is listed with H/W Type
“UNKNOWN” you may need to install the appropriate drivers.
Use the ‘sam’ utility. Sam runs as a mouse driven GUI (Figure 1) on a system with full graphics
capability, or as a console text-based interface (Figure 2). If you use the text-based interface, use the
Tab and arrow keys to navigate, and the Return key to select.
