Storage managers have slightly different installation and
configuration requirements. If you use a third-party storage manager,
make sure that you follow the manufacturer instructions carefully.
If you have difficulty with the storage-manager installation and configuration,
contact the manufacturer directly.
About this task
For the list of certified storage managers for your
ON-Bar version,
consult your marketing representative.
Important: Some
storage managers let you specify the data to back up to specific storage
devices. Configure the storage manager to back up logical logs to
one device and storage spaces to a different device for more efficient
backups and restores.
To configure a third-party storage
manager:
Procedure
- Set ON-Bar configuration
parameters and environment variables.
- Configure the storage manager so that ON-Bar can
communicate correctly with it.
For information, see your
storage-manager documentation.
- Configure your storage devices by following the instructions
in your storage-manager documentation.
The storage manager
must know the device names of the storage devices that it uses.
- Label your storage volumes.
- Mount the storage volumes on the storage devices.
- Create the storage-manager definition in the sm_versions file.
Use the definition provided by the vendor of the third-party storage
manager.
- Copy the sm_versions.std template
to a new file, sm_versions in the $INFORMIXDIR/etc directory
on UNIX™ or the %INFORMIXDIR%\etc directory
on Windows™.
- Create your own sm_versions file
with the correct data for the storage manager by using the format
in sm_versions.std as a template. To find out
which code name to use in sm_versions for third-party
storage managers, see the storage-manager documentation.
- Stop any ON-Bar processes
(onbar_d, onbar_w, or onbar_m)
that are currently running and restart them for the changes to take
effect.
- Verify that the BAR_BSALIB_PATH configuration parameter
points to the correct XBSA shared library for your storage manager.
- If you enabled
deduplication for your storage manager, set the IFX_BAR_USE_DEDUP
environment variable and restart the database server.
-
ON-Bar uses
the value of the SERVERNUM configuration parameter as part of the
storage path for the logical logs in the storage manager. If the storage
manager does not use a wildcard for the server number, set the appropriate
server number environment variable for the storage manager.
What to do next
After you configure the storage manager and storage devices
and label volumes for your database server and logical-log backups,
you are ready to initiate a backup or restore operation with ON-Bar.
