If you are using Veritas Storage Foundation for DB2 to set up a new database, complete these tasks in the order listed below:
Determine the number and sizes of file systems you need for the database you want to create. |
See the Veritas File System Administrator's Guide. |
Create volumes to meet your file system needs. You can use disk mirroring as a safeguard against disk failures and striping for better performance. |
|
If you plan to create volume snapshots for the database and use them on either the same host or a secondary one, ensure that your volume layout is consistent with Database FlashSnap requirements. |
|
Create the VxFS file systems you need on the volumes. |
|
Install and configure your database. You must create Quick I/O files before creating the tablespaces. |
|
If you would like the ability to view detailed storage stack topology information to ensure your storage stack configuration is optimized for the database, configure and use Storage Mapping. |
See About Storage Mapping . |
If you want to use Database FlashSnap for off-host processing after converting your database files to use Quick I/O or ODM and your volume layout is inconsistent with Database FlashSnap requirements, you will need to "relayout" your volume manager configuration after your database files have been converted. |
See the Veritas Volume Manager Administrator's Guide. |
If you are not currently running on VxVM and VxFS, make sure Veritas Storage Foundation for DB2 is installed and convert your existing database configuration. |
See the Veritas Storage Foundation for DB2 Installation Guide. |
For backup and recovery on the same host, you can use the Storage Checkpoint facility to create file system snapshots of the database. A Storage Checkpoint creates an exact image of a database instantly and provides a consistent image of the database from the point in time the Storage Checkpoint was created. |
