Page 6: Introduction
For optimum performance it is important to use a backup application that supports the drive’s features within your system’s configuration. For details of which backup applications are supported with your tape drive and system, visit the HP Tape Compatibility website: http://www.hp.com/products1/storage/compatibility/tapebackup/index.html. -
Page 7: Hp (Hp-Ux) Servers And Workstations
For supported versions of HP-UX, go to http://www.hp.com/go/connect. Before you install your tape drive, visit the HP web site, www.hp.com, and search to locate IT Resource Center (you may be required to set up a new login). Download the latest hardware enablement (HWE) patch bundle for your operating system. -

Page 9: Adding Stape/Estape And Eschgr/Schgr (Media Changer Driver) To The Kernel
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. -

Type “m to modify the stape driver and “s” to set it to “static”. The Planned State will now read “static”. The stape driver is now added to the kernel. If you are going to attach a media changer, use a similar procedure to change eschgr or schgr to “static”. HP (HP-UX) servers and workstations... -

Page 14: Using Large Block Sizes
The maximum block size limit of 256 KB (262144 bytes) applies to all versions of HP-UX and is strongly recommended for broad backup/restore compatibility across all supported HP-UX versions. Different HP-UX kernel configurations or later versions of HP-UX may not use 256 KB ‘chunks’... -

Page 26: Kernel Patch Levels
Device file variants for a given tape device are listed in /dev/rmt with various suffixes—l, m, h, u, c specifying the ‘density’ (low, medium, high, ultra, compressed), plus additional options b, ‘Berkeley’ behavior, and n, no rewind behaviour. HP recommends the ‘Berkeley’ device file option for most applications with compressed density c: /dev/rmt/0cb or /dev/rmt/... - Page 27 Use is subject to license terms. #pragma ident "@(#)st.conf 1.34 04/06/24 SMI" add the following (there are 6 significant spaces between the first occurrences of HP and Ultrium in line 2): tape-config-list = "HP Ultrium 5","HP Ultrium LTO 5","HP_LTO_GEN_5"; HP_LTO_GEN_5 = 2,0x3B,0,0x18659,4,0x00,0x44,0x46,0x58,3,60, 1200,600,1200,600,600,18000 name="st"...

Page 28: Hp-Data Values
“Verifying the installation” on page 31 provides instructions on backing up and restoring a sample file to test your installation. HP-data values The values for HP_LTO_GEN_n and name, which provide normal LTO mode, have the following meanings: The syntax for HP_LTO_GEN_n is: <drive type>... - Page 29 Parameter Value Meaning Variable record size not limited to 64 KB. 0x8000 Device determines which of the two mode pages the device 0x10000 supports for selecting or deselecting compression. So 0xd639 indicates variable record length, bsf and bsr enabled, long timeouts for erase, EOD recognition, Unloadable device driver, 5 x longer timeouts, buffer writes and pre-acknowledge success, variable records not limited to 64 KB, auto-density over-ride and MODE SELECT compression.
