LTO-3 Tape Drive User’s Guide

For example, the command

.dmesg | egrep .target. | sort | uniq.

can find all

SCSI controllers and SCSI targets. The output may look similar to:

sd32

at

ithps0:

target2

lun0

sd34

at

ithps0:

target4

lun0

st21

at

ithps1:

target0

lun0

st22

at

ithps1:

target1

lun0

In this case, the LTO-3 Tape Drive can be set for SCSI ID address 2

through 6 and attached to controller ithps1 (this particular controller also

supports SCSI addresses 8 through 15).

Types of
Controllers

6

You may be able to view the main pages of three types of SCSI controllers

for Sun Sparc systems:
• esp
• glm
• isp
We recommend that the LTO-3 Tape Drive not be attached to esp

controllers. This controller is not fast enough to work with the LTO-3

Tape Drive. The minimum recommended controller would be a glm

controller, which is an Ultra Wide controller.
We recommend Ultra 160 SCSI-capable controllers capable of 80MB/s

data transfer as a minimum. Slow backups will result if using slower SCSI

controllers.

Configuring the
Device File st.conf

6

To configure Solaris 2.4 and above to use the LTO-3 Tape Drive correctly,

add the following lines to the file

st.conf

in the directory /kernel/drv.

tape-config-list=

"SEAGATE ULTRIUM06242-XXX", "Seagate LTO 1", "SEAGATE_LTO1",

"CERTANCEULTRIUM 2", "Seagate LTO 2", "Certance_LTO2",
"CERTANCEULTRIUM 3", "Seagate LTO 3", "ULTRIUM",

# THE LAST ENTRY IN THIS SECTION MUST END WITH A SEMICOLON

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;
