SEAGATE_LTO1 = 1,0x3b,0,0x1d639,4,0x00,0x00,0x00,0x00,1;

Certance_LTO2 = 1,0x3b,0,0x1d639,4,0x00,0x00,0x00,0x00,1;

Certance_LTO3 = 1,0x3b,0,0x1d639,4,0x00,0x00,0x00,0x00,1;

Quantum_LTO3 = 1,0x3b,0,0x1d639,4,0x00,0x00,0x00,0x00,1;

The value 0x1d639 equates to the way the LTO-3 Half-Height Tape

Drive is configured to operate in the Solaris environment. This value

enables the LTO-3 Half-Height Tape Drive to support:

• Variable-length records (variable-length block size), not limited

to 64 Kbytes

• Long time outs (5 times longer than normal) for long erase

functions (Attempting to erase the entire tape is not

recommended.)

• End of data detection

• Backspace over:

• Files (same as

mt bsf command to backspace over file marks)

• Records (same as

mt bsr command to backspace over

individual tape blocks)

• Unloadable device drivers

• Buffered write operations

• Mode Select Page 10h operations to enable/disable data

compression

2 After modifying the

st.conf file, use the boot-r command to restart the

system and reconfigure the kernel.

a If you are replacing a tape device with the same SCSI ID, you

might want to delete the st devices from the

/dev/rmt directory.

(This is recommended.)

b When using commands that require a blocking factor, such as

tar

ufsdump, the preferred factor is:

• 128 (optimal)

• 64 (minimal)
