dbdst_classify -S ORACLE_SID -M mount_device
     -v vol:class,vol:class,...

rpm -qa | grep VRTSdbed


The dbdst_classify command is used to classify an existing DBDST ready MVS filesystem. DBA need to specify which storage_class each volume belongs to. Storage classes used in in this command must be predefined using dbdst_admin. It is important to note that maxclass and minclass are not enforced and are advisory only. This command can be executed when database is online. The MVS filesystem indicated by the mount_device should be available and mounted.


The following options are supported:
  Specifies the name of the Oracle database whose information will be retrieved.
-M mount_device
  Specifies the block device where the file system resides. This should be of the form /dev/vx/dsk/<dgname>/<vsetname>
-v vol:class,vol:class
  Specifies a comma separated list of vol:class pairs which indicate the volume name and the storage class it belongs to. The storage_class specified by the class must be registered earlier using dbdst_admin comand.

Real Application Clusters (RAC) Considerations

This command is supported in a RAC environment. This command can be run on any node of the RAC.


This example shows how to classify volumes vol1 as storage class GOLD and vol2, vol3 as storage class SILVER for a filesystem on device /dev/vx/dsk/oradata/arch.

$ /opt/VRTS/bin/dbdst_classify -S PROD -M /dev/vx/dsk/oradata/arch -v vol1:GOLD,vol2:SILVER,vol3:SILVER


This command must be run as Oracle DBA user. This command can be executed when the database is online.

dbed_update must be run at least once before this command to ensure an up-to-date repository.

dbdst_admin must be run at least once before this command to ensure storage class is registered.

The mount_device must be converted to DBDST filesystem using dbdst_convert command before this command.
