Installing Oracle Secure Backup on Linux or UNIX with installob

If you choose to create attach points later, or if you add a tape device to a
media server in the future, then see
"Creating Attach Points with makedev" on
page 2-12 for two alternative methods of completing this task.
■
Enter
yes
to configure tape devices now.
To create attach points, the
installob
script asks if tape libraries are
connected to this host, and if so, what the SCSI parameters are for each tape
library. After you have entered the tape library SCSI parameters, the
installob
script asks you to confirm your entries.
When you have entered information about tape libraries attached to this host,
the
installob
script asks the same questions about standalone tape drives.
Table 2–2 lists the information required by
installob
for each platform. For
the device type, enter a
d
for a tape drive or
l
(lowercase
L
) for a tape library.
Enter each parameter value in response to the prompts from the
installob
script. You can press Enter to accept a default value, but the default SCSI
parameters offered by the script might not be correct.
When you have entered the SCSI parameters for all tape libraries and tape
drives attached to this host, the
installob
script begins device driver
configuration and device special file creation.
Record the name of the device special file created for each tape device. The
filename is needed when you configure the
attachment
for the tape device, as
part of configuring the Oracle Secure Backup domain. The filename should be
/dev/obt n
for tape drives, and
/dev/obl n
for tape libraries, where n is the
Oracle Secure Backup LUN you entered for the tape device.
If you enter the wrong parameters, then device special file creation fails. To
resolve the resulting errors, run
installob
again, entering the correct values,
or use the
makedev
script described in "Creating Attach Points with
makedev" on page 2-12.
When the
installob
script has created attach points for all tape devices
attached to this host, it reminds you that you must configure these tape
devices through the Oracle Secure Backup Web interface or the command line
using the
mkdev
command in
obtool
.
