The file system used by the production database in this example originally resides
on the single volume oralog, which must be prepared by adding volumes and
placement classes assigned to the volumes.
To add the NEW, MEDIUM, and OLD storage classes
◆
Use the dbdst_admin command as follows:
$ /opt/VRTS/bin/dbdst_admin -S PROD -o addclass=\
NEW:"EMC Storage for Production DB"
$ /opt/VRTS/bin/dbdst_admin -S PROD -o addclass=\
MEDIUM:"Clarion Storage for Production DB"
$ /opt/VRTS/bin/dbdst_admin -S PROD -o addclass=\
OLD:"JBOD Storage for Production DB"
To convert the database's file system and add volumes for use with SmartTier for
Oracle
◆
Use the dbdst_convert command as follows:
$ /opt/VRTS/bin/dbdst_convert -S PROD \
-M /dev/vx/dsk/oradg/oralog -v emc_v1,clarion_v1,jbod_v1
