Creating Attach Points with makedev
2-16 Oracle Secure Backup Installation and Configuration Guide
You can convert the hexadecimal values of
lun_id
and
scsi_id
(shown in bold)
to decimal so that they are usable by the Oracle Secure Backup
makdev
command.
After conversion, the SCSI LUN ID is 281474976710656 and the SCSI ID is 2.
3.
Navigate to the
install
directory in your Oracle Secure Backup home. For
example:
# cd /usr/local/oracle/backup/install
4.
Enter the
makedev
command at the shell prompt:
# makedev
5.
At the prompts, enter the information required to create attach points used within
Oracle Secure Backup to identify devices for backup and restore operations.
The
makedev
script creates the attach point, displaying messages indicating its
progress.
Identifying and Configuring HP-UX Devices
To access SCSI or Fibre Channel tape devices on HP-UX using the
makedev
script,
Oracle Secure Backup
requires the following identifying information about how the
devices are attached to their hosts:
■
SCSI bus number instance
■
Target ID
■
LUN
To gather device information in HP-UX, you can use the
ioscan
utility located in
/usr/sbin
on the HP-UX operating system. The
ioscan
command searches the
system and lists any devices that it finds. You must have root access to run
ioscan
.
To identify and configure HP-UX devices:
1.
Log on as
root
.
2.
Execute the following command:
/usr/sbin/ioscan -f
Running the command with the
-f
option displays full information about the
system configuration including device class, instance number, device or interface
driver, software state, and hardware type.
Example 2–1 shows sample output for
ioscan -f
. The bus number instance,
target ID, SCSI LUN, and device description for each device are shown in bold.
Example 2–1 ioscan -f
$ /usr/sbin/ioscan -f
Class I H/W Path Driver S/W State H/W Type Description
...
ext_bus 3 0/1/1/ 1 mpt CLAIMED INTERFACE SCSI Ultra320
target 11 0/1/1/1. 1 tgt CLAIMED DEVICE
Note:
The
ioscan
tool is provided as an optional tool for device
identification in HP-UX environments. The
ioscan
tool is not
included as part of any
Oracle Secure Backup
installation.
