HCD UIMs supplied by IBM are part of the product that supports the associated device. For example, the UIM supporting, 3380s and 3390s is part of DFSMSdfp. Therefore, your installation has access to UIMs only for the products it uses. Some device types are defined as another device type. You can use the HCD query and print facility to determine if MVS supports a particular device.

The following partial list of the IBM-supplied HCD UIMs shows the product that contains the UIM and the devices the UIM defines.

In addition to the UIMs listed above, there are UIMs shipped with HCD that complement device values for VM systems. The names of these UIMs range from CBDUS257 to CBDUS512.
