Hp-Data Values - HP LTO-4 Technical Reference Manual

4. You should now be able to use the drive.
• Use /dev/rmt/Xcb if you require a compression rewind device file, where X is the
relevant device address.
• Use /dev/rmt/Xcbn when you require a compression non-rewind device.
Once the device files have been created, you should confirm that your new tape drive is working
properly. Chapter 8 on page 37
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 on Solaris 8/9/10 is:
<drive type> = <version>, <type>, <bsize>, <options>,
<no. of densities>, <density 0>, <density 1>,
<density 2>,<density 3>, <default density>,
<non-motion timeout>, <read/write timeout>,
<rewind timeout>, <space timeout>, <load timeout>,
<unload timeout>, <erase timeout>
where:

<type>
<bsize>
<options>
34 Sun (Solaris 8, 9, 10) servers and workstations
provides instructions on backing up and restoring a sample file to
Value Meaning
1 or 2 Indicates the format of the following parameters.
0x36 or The value for an LTO Ultrium drive in
/usr/include/sys/mtio.h. For Solaris 8, 0x36 indicates a
0x3B
type of MT_ISOTHER. Later versions of Solaris support the value
0x3B which indicates a type of MT_LTO.
Indicates variable block size.
0
This value is derived from constants provided in
0xd639
or /usr/include/sys/scsi/targets/stdef.h. The value
determines which operations the driver can perform with the
0x18659
attached device by using a unique value for each feature and then
adding them together to form the options value. Supported features
will vary with OS revision, and may include the following:
0x001
0x008
0x010
0x020
0x040
0x0200 Device knows when end of data has been reached.
0x0400 Device driver is unloadable.
Device supports variable length records.
Device can backspace over files (as in the 'mt bsf'
option).
Device supports backspace record (as in 'mt bsr').
Device requires a long time-out period for erase
functions.
Device will automatically determine the tape density.
