To view one of the operator displays, press its corresponding character key. The lowercase characters a through w display operational information.
Note - The uppercase samu(1M) displays (C, D, F, I, J, K, L, M, N, P, R, S, T, and U) are designed to be used at a customer site only with the assistance of a member of the technical support staff.
This topic does not describe these uppercase displays in detail.
When an operator display overflows the available screen area, the word more appears on the bottom of the display indicating additional information, as shown in the following example. Press Ctrl-F to page forward and see more content.
Example 13-1 samu Screen Indicating More Text Can Be Obtained

When samu prompts you to provide a device, enter its associated equipment number. The configuration display (c) shows equipment numbers for all removable media devices. To control all displays, use the control keys listed for the display.
The following sections describe the operator displays in alphabetical order with examples. Descriptions of more complex displays are followed by a table describing the field in the display.
Note - If you are using only the Sun QFS software without the archiving features of SAM-QFS, not all operator displays will be available.
The a display shows the archiver status. To display archiving details for a specific file system:
a filesystem
For filesystem, specify the name of a file system.
The following table shows the control keys you can use in the a display.

You can use the samu down, off, and on device state commands to change device states. You can issue these commands from any samu display, but if you issue them from the c, m, o, r, s, or t display, you can see the change in the display.
The following procedure show how to change a device's state from down to on.
command:off eq
where eq is the equipment number of the device.
For example:
Command:on eq
For eq, specify the equipment number of the device.
