EMC z/OS Storage Manager.
An empty screen is presented when a UCB for a Thin Device is entered on screen ECHRGDEV.
Screen ECHRGDEV does not permit the entry of a SYMDEV, which means it cannot display the DA0IF for a Data Device.
Thin Devices are not directly related to DA-IF(s). Only Data Devices are; Data Devices do have a symdev number.
EzSM does not permit entry of SYMDEVs on panel ECHRGDEV; which means the DA-IF(s) for Data Devices may not be displayed.
Use of Thin Devices.
The screen is working as designed. Thin Devices do not have DA-IF information so there is nothing to present back to the user.
To obtain DA-IF information for a Data Device, enter the command:
1.<count> is the number of consecutive devices to display
2.<data-device-symdev-number> is the symdev for the first data device to display
