Performing System Operation Tasks

Removing and Returning System Devices 

From time to time, it may be necessary to remove peripheral devices from,
and return devices to, the system.  Use the DOWN and UP commands,
respectively, to do so.

To remove a device from system use 

To remove a device from the system, type the DOWN command followed by the
LDEV number of the device.  For example, to down LDEV 23, enter:

     DOWN 23 


CAUTION  When a device is powered down, subsequent access to that device
         can result in indefinite waiting, erroneous transfers, or other
         incorrect operations.  Often these failures occur with no
         indication to the system operator or to the user.  For these
         reasons, use the DOWN command before a device is powered down
         for removal.  This commands does not apply to the console or to
         disk drives.


To return a device for system use 

To return a particular device to its normal function on the system, use
the UP command.  For example, to bring LDEV 23 back up, enter:

     UP 23
