Changing the Device Class of a Data Set
To change the device on which a data set resides, use the CHANGE
DEVICECLASS command. The CHANGE DEVICECLASS command actually moves the
data set. In this section, a different device class is specified for the
data set SUP-MASTER in the ORDERS database. Before changing the device
class, the REVIEW SETS command output looks like this:
Set Blk Blk Dev
No. Data Set Name Type Capacity Fac Max Class Security
--------------------------------------------------------------
5 SUP-MASTER M 201 12 1024 DISK1 (13/12,18) <---- *
*device class to be changed
In the example below, the device class is changed from DISK1 to DISK2.
The DBCPLUS program displays a message confirming that the device class
has been changed.
>change deviceclass sup-master disk2
Change of set capacity, block factor, and/or device class accepted.

Refer to "CHANGE DEVICECLASS" in chapter 10, "DBChange Plus Commands,"
for a detailed description of the command syntax and parameters.
If you want to verify that the device class for the SUP-MASTER data set
is changed, use the REVIEW SETS command as follows. You can see that the
device class is now DISC2.
