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.

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 densi ties>, <d ensity 0> , <densit y 1>,
<dens ity 2>,< density 3 >, <defau lt densit y>,
<non- motion t imeout>, <read/wri te timeou t>,
<rewi nd timeo ut>, <spa ce timeou t>, <load timeout> ,

<version>
1
or 2
Indicates the format of the following parameters.
<type>
0x36
or
0x3B
The value for an LTO Ultrium drive in
/usr/include/sys/mtio.h
. For Solaris 8, 0x36 indicates a
type of MT_ISOTHER. Later versions of Solaris support the value
0x3B
which indicates a type of MT_LTO.
<bsize>
0
Indicates variable block size.
<options>
0xd639
or
0x18659
This value is derived from constants provided in
/usr/include/sys/scsi/targets/stdef.h
. The value
determines which operations the driver can perform with the
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
Device supports variable length records.
0x008
Device can backspace over files (as in the ‘mt bsf’
option).
0x010
Device supports backspace record (as in ‘mt bsr’).
0x020
Device requires a long time-out period for erase
functions.
0x040
Device will automatically determine the tape density.
0x0200
Device knows when end of data has been reached.
0x0400
Device driver is unloadable.
