b. Unload the kernel module:

# modunload -i 96

c. Load the kernel module back in:

# modload -p drv/st

d. Rebuild the device paths:

devfsadm -C

devfsadm -i st

3. You should now be able to use the drive.

• Use /dev/rmt/Kcb if you require a compression rewind device file, where K is the

relevant device file instance.

• Use /dev/rmt/Kcbn 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. “Verifying the installation” (page 25) 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> = <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>,

where:

MeaningValueParameter

Indicates the format of the following parameters.1 or 2<version>

The value for an LTO drive in /usr/include/sys/mtio.h. The value 0x3B

indicates a type of MT_LTO.

0x3B<type>

Indicates variable block size.0<bsize>

This value is derived from constants provided in

/usr/include/sys/scsi/targets/stdef.h. The value determines which

0xd639 or

0x18659

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:

Device supports variable length records.0x001

Device can backspace over files (as in the ‘mt bsf’ option).0x008

Device supports backspace record (as in ‘mt bsr’).0x010

Device requires a long time-out period for erase functions.0x020

Device will automatically determine the tape density.0x040

Device knows when end of data has been reached.0x0200

Device driver is unloadable.0x0400
