Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

■ You must convert the single-volume file system on which you plan
to implement Database Dynamic Storage Tiering.
■ The file system should be unmounted when you run the
dbdst_convert command.
■ If the file system has n volumes, volumes 1 through n–1 will be
placed in the storage class "PRIMARY" and volume n will be placed
in the storage class "SECONDARY."
■ The volumes specified when running the conversion must be in
the same disk group as the mount device.
Usage notes
To convert a mount device from a single volume device to a volume set
1
Use the dbdst_convert command as follows:
$ /opt/VRTS/bin/dbdst_convert -S $ORACLE_SID -M mount_device -v \
volume_name,volume_name
2
Bring database objects online.
For example, to convert a volume-based oradata file system to a Database Dynamic
Storage Tiering-ready volume set file system on mount device
/dev/vx/dsk/oradg/oradata, use the dbdst_convert command as follows:
$ /opt/VRTS/bin/dbdst_convert -S PROD -M /dev/vx/dsk/oradg/oradata -v \
new_vol1,new_vol2
After conversion, you will have a volume set named oradata containing three
volumes (oradata_b4vset, new_vol1, and new_vol2). The file system will have two
storage classes defined as PRIMARY and SECONDARY. The volumes will be
assigned as follows:
■ PRIMARY storage class will contain volumes oradata_b4vset and new_vol1.
■ SECONDARY storage class will contain volume new_vol2.
Classifying volumes into a storage class
Before creating a DST policy or manually moving data, assign classes to your
volumes.
Before assigning classes to volumes, review the following information:
