Wait a short time and reenter the command. If VTAM continues to issue this message, enter the DISPLAY STORUSE command to display storage usage for storage pools.

If this message does not appear in the display, you might need to reissue the DISPLAY STORUSE command, specifying a higher value for the NUM operand.
