Veritas Storage Foundation 5.1 SP1: Storage and Availability Management for Oracle (5900-1504, April 2011)

For example, to convert the volume-based file system oradata to a SmartTier
for Oracle-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 SmartTier policy or manually moving data, assign classes to
your volumes.
Before assigning classes to volumes, review the following information:
■ You must convert your Veritas File System file
system to a multi-volume file system first.
■ Storage classes must be registered using the
dbdst_admin command before assigning
classes to volumes.
■ The database can be online or offline.
Usage notes
To classify a volume
■ Use the dbdst_classify command as follows:
$ /opt/VRTS/bin/dbdst_classify -S $ORACLE_SID -M mount_device \
-v volume_name:class[,volume_name:class]
For example, to assign the class "FAST" to volume new_vol1, use the
dbdst_classify command as follows
Displaying free space on your storage class
To see the free space, class information, and volume information on your storage
classes, use the dbdst_show_fs command.
Table 14-2 shows the dbdst_show_fs command options.
