IBM 3590 - Manual (Page 36)

Intervention Messages
The intervention screen displays intervention messages on the operator panel.
The intervention screen consists of an 8-character intervention message that is
displayed in a large font and a prompt. The prompt indicates that pressing
Enter allows access to the Options menu. The screen also has device status
information and a 2-line message area in the standard font. A drive type is
displayed (see Table 2 on page 9).
Figure 6 shows the intervention screen with an example of a Mount
command. The Mount command prompts the operator to mount a tape with
the volume serial (volser) 123567. In this example, M means mount and S
means scratch.
Table 4 describes messages that can be displayed for the 3590.
