Using the
ioscan
output, make a note of the bus number, target ID, and SCSI
LUN for the tape devices.
Table 2–4 shows the relevant information from Example 2–1 .
4.
Use
makedev
to create attach points so that Oracle Secure Backup can identify
devices for backup and restore operations.
The following example runs
makedev
using the information in Table 2–4 . The
example creates the attach point
/dev/obl/8
for the ADIC FastStor 2 library on
SCSI bus instance 3 with the target ID 1 and SCSI LUN 0.
% makedev
Enter logical unit number 0-31 [0]: 8
Enter 'd' if this device is a tape drive or 'l' if a SCSI-2 addressable
tape library [d]: l
Enter SCSI bus instance: 3
Enter SCSI target id 0-16777215: 1
Enter SCSI logical unit number (lun) 0-7 [0]: 0
/dev/obl/8 created
The following example runs
makedev
using the information in Table 2–4 . The
example creates the attach point
/dev/obt/9m
for the HP Ultrium 2 tape drive on
SCSI bus instance 3 with the target ID 2 and SCSI LUN 0.
% makedev
Enter logical unit number 0-31 [0]: 9
Enter 'd' if this device is a tape drive or 'l' if a SCSI-2 addressable
tape library [d]: d
Enter SCSI bus instance: 3
Enter SCSI target id 0-16777215: 2
Enter SCSI logical unit number (lun) 0-7 [0]: 0
/dev/obt/9m created
