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.
