Parameter

Value

Meaning

 

 

 

 

<bsize>

0

Indicates variable block size.

 

 

 

<options>

0xd639 or

This value is derived from constants provided in /usr/include/sys/

 

0x18659

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.

 

 

0x1000

Time-outs five times longer than normal.

 

 

0x4000

Driver buffers write requests and pre-acknowledges success

 

 

 

to application.

 

 

0x8000

Variable record size not limited to 64 KB.

 

 

0x10000

Device determines which of the two mode pages the device

 

 

 

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 sucess, variable

 

 

records not limited to 64 KB, auto-density over-ride and MODE SELECT

 

 

compression.

 

 

 

<no. of

4

There are four densities following in the parameter list.

densities>

 

 

 

 

 

 

<density n>

0x00

Creates a device file with compression disabled.

 

 

 

<density 3>

0x40,

The density code for data compression enabled by default.

 

0x42 or

 

 

 

0x44

 

 

 

 

 

<default

3

Density 3 (0x44) is the default for Generation 3 drives.

density>

 

 

 

 

 

 

<X timeout>

 

All timeouts are in seconds

Values for the parameters for name are as follows:

X specifies the SCSI ID (target) of the device.

 

 

 

lun

0

Specifies the LUN for the device.
