Configuring Tape Drives

The IBM library contains 2 IBM Ultrium LTO drives, one with SCSI ID 4, SCSI LUN 0 and

the other with SCSI ID 5, SCSI LUN 0.

Use the following procedure to create the robotic control device files and the passthru

driver tape drive device files:

1. Assume the configuration from ioscan -f is as follows:

Class I H/W Path Driver S/W State H/W Type Description

=================================================================

ext_bus 7 0/7/0/ c720 CLAIMED INTERFACE SCSI C896 Fast

Wide LVD

target 10 0/7/0/1.0 tgt CLAIMED DEVICE

tape 65 0/7/0/1.0.0 stape CLAIMED DEVICE QUANTUM SuperDLT1

target 11 0/7/0/1.1 tgt CLAIMED DEVICE

tape 66 0/7/0/1.1.0 stape CLAIMED DEVICE QUANTUM SuperDLT1

target 12 0/7/0/1.2 tgt CLAIMED DEVICE

autoch 14 0/7/0/1.2.0 schgr CLAIMED DEVICE ADIC Scalar 100

target 13 0/7/0/1.3 tgt CLAIMED DEVICE

autoch 19 0/7/0/1.3.0 schgr CLAIMED DEVICE IBM ULT3583-TL

target 14 0/7/0/1.4 tgt CLAIMED DEVICE

tape 21 0/7/0/1.4.0 atdd CLAIMED DEVICE IBM ULT3580-TD1

target 15 0/7/0/1.5 tgt CLAIMED DEVICE

tape 19 0/7/0/1.5.0 atdd CLAIMED DEVICE IBM ULT3580-TD1

Note Use the IBM atdd driver when configuring IBM tape drives on HP-UX. Configure

atdd and BEST device paths according to IBM driver documentation. Do not

configure atdd for robotic control of IBM robots. Check the VERITAS support web

site for the latest recommended atdd driver version from IBM.

2. The commands to create the robotic device files follow. See the “Command Summary”

on page 70 for the mknod command format or see the scsi_ctl(7) man page.

cd /dev/sctl

/usr/sbin/mknod c7t2l0 c 203 0x072000

/usr/sbin/mknod c7t3l0 c 203 0x073000

This creates the following device files, which you specify to Media Manager during

configuration of the ADIC robotic control and IBM robotic control respectively:

/dev/sctl/c7t2l0

/dev/sctl/c7t3l0
