UP Command The UP command places the specified subdevices back in service.
UP { # subdevice | * }
# subdevice
specifies an individual subdevice or a class of subdevices, such as printer
subdevices, to be placed back in service.
subdevice consists of the name of a class of subdevices and, optionally, the unit
number of an individual subdevice within the specified class of subdevices. The
unit number must immediately follow the subdevice class name with no
intervening blanks.
The subdevice class name must be one to six alphanumeric characters, of which
the first must be a letter. It must be the name of a subdevice class that was defined
when the line server was started.
The unit number must be a number between one and the maximum number of
subdevices of the specified class that are supported by the line server.
If you specify the unit number, only that particular subdevice is placed back in
service. If you omit the unit number, all subdevices of the specified class are
placed back in service.
*
specifies all subdevices in all classes. In this case, all subdevices are placed back in
service.
Considerations The UP command places the specified subdevices back in service. A subdevice is
taken out of service by the DOWN command. After a subdevice has been taken out of
service, that subdevice cannot be used by any process, including other Exchange/SNA
command interpreters, until it is put back in service with the UP command. After a
subdevice has been placed back in service by the UP command, any process, including
other Exchange/SNA command interpreters, can use that subdevice again.
In order to use the UP command, the command interpreter must be privileged with
respect to the line server (that is, the command interpreter must have the same
accessor (user) ID as the command interpreter that started the line server). If the
command interpreter is not privileged with respect to the line server, an error message
is displayed and no subdevices are taken out of service.
