Configuring Peripherals to the System
Peripheral devices are configured to the system with the I/O Configurator
subsystem of the new SYSGEN utility. (System volumes, other than the
master system volume on ldev 1, and nonsystem volumes are configured with
the volume management utility VOLUTIL.) For information on how the SYSGEN
utility works, refer to Chapter 3 of this manual.
To enter the I/O Configurator from the MPE XL prompt enter:
:SYSGEN
then
SYSGEN>IO
The I/O Configurator provides a series of commands for adding, modifying,
deleting, and listing devices and device classes. Each command includes
a complete set of parameters for specifying the characteristics of the
subject device or device class.
Modifying the System Configuration for a Device
The following describes the procedure for modifying a device. It is
typical of the procedures used in the I/O Configurator.
The command to modify devices is MDEV. It is used with all devices. The
syntax of the command and its parameters are displayed in Example 8-1 and
Table 8-1 .

| MDEV ldev = logical device # |
| [newldev = logical device #] |

--------------------------------------------------------------------------------------------
| | |

--------------------------------------------------------------------------------------------
| | |
| newldev | The new logical device number that will be assigned to the device. |
| | |
--------------------------------------------------------------------------------------------
| | |
| id | The new Hewlett-Packard number by which the product is identified. |
| | |
--------------------------------------------------------------------------------------------
| | |
| path | The new hardware address of the device; new devices are added to |
| | existing paths. Paths can accept eight devices, although HP-IB |
| | device adapters support six devices. The format of the path name is |
| | system dependent. Refer to Chapter 2 of this manual for a |
| | description of path names. For additional information, refer to |
| | System Startup, Configuration and Shutdown Reference Manual |
| | (32650-90042). |
| | |
--------------------------------------------------------------------------------------------
| | |
| class | The name of the class to which the device belongs. |
| | |
--------------------------------------------------------------------------------------------
| | |
| mode | The new mode in which the device will operate where: |
| | |
| | JOB = job or session accepting device; |
| | |
| | DATA = data accepting device; |
| | |
| | INTERACTIVE = interactive device; input=output; |
| | |
| | DUPLICATIVE = a device that echos inputs to its output; |
| | |
| | INPUT = initially spooled for input; |
| | |
| | OUTPUT = initially spooled for output; |
| | |
| | AUTOREPLY = automatically allocates a device to a user without an |
| | intervening :REPLY command; |
| | |
| | NONE = none of the above apply. |
| | |
| | Multiple modes can be specified by separating them with commas and |
| | surrounding them by parentheses. |
| | |

Table 8-1. >MDEV Parameters (cont.)
--------------------------------------------------------------------------------------------
| | |
| Parameter | Description |
| | |
--------------------------------------------------------------------------------------------
| | |
| outdev | The new logical device (LDEV) number or device class of the output |
| | device to which the device being added is assigned. |
| | |
--------------------------------------------------------------------------------------------
| | |
| rsize | The new characteristic record size of the device. |
| | |
--------------------------------------------------------------------------------------------
| | |
| pmgr | The new name of the physical device manager associated with the |
| | specified path; can be up to 32 alphanumeric characters long. |
| | |
--------------------------------------------------------------------------------------------
| | |
| lmgr | The new name of the logical device manager associated with the |
| | specified path. |
| | |
--------------------------------------------------------------------------------------------
| | |
| pmgrpri | The new priority level at which the physical device manager executes. |
| | |
--------------------------------------------------------------------------------------------
| | |
| mpetype | Compatibility Mode type; obtained from the IODFAULT.PUB.SYS file for |
| | all Hewlett-Packard devices. |
| | |
--------------------------------------------------------------------------------------------
| | |
| mpesubtype | Compatibility Mode subtype; obtained from the IODFAULT.PUB.SYS file |
| | for all Hewlett-Packard devices. |
| | |
--------------------------------------------------------------------------------------------
The syntax for all of the commands associated with adding, modifying, and
deleting devices include required and optional parameters. Optional
parameters are designated by brackets. If you choose one of the optional
parameters, use commas as place holders for any required parameters
before specifying the optional parameter.
Any parameter can be specified positionally or by keyword. If specified
by keyword, a parameter cannot be specified ahead of any parameter that
is specified positionally.
The symbol | in the syntax means you can choose any of the options that
apply. These options are device dependent. For example, some devices,
such as terminals, can be both input and output devices, but a printer
can be an output device only. If more than one option is specified,
enclose the parameters in parentheses and separate with commas.
Modify a Device with >MDEV
In the following example, the command is used to modify the configuration
of a printer identified as LDEV 27.
Access the I/O Configuration program of SYSGEN by entering:
:SYSGEN
The screen displays:
SYSGEN>
Enter:
SYSGEN>IO
The screen displays:
IO>
Check the configuration for the printer device class (LP and PP) to
verify the LDEV number of the device to be modified by entering:
IO>LCLASS CLASS= LP,PP
The following is displayed:
CLASSNAME MODE MIN MODE DCC MODE # DCC LDEV
--------- ------- -------- -------- ----- ----
LP default out 0 6, 19, 27,
PP default out 0 19, 27,
To change printer LDEV 27 from the device class PP to FASTPP, enter
either :
IO>MDEV 27 CLASS=FASTPP
or
IO>MDEV 27 ,,,,FASTPP
To verify the modification, enter:
IO>LDEV 27
The following list is displayed:.
LDEV PATH DEVICE ID
---- -------------------------------- ----------------------------
27 8.2.9 HP2680
LDEV OUTDEV DEV TYPE JAID R xS RSIZE CLASS
---- -------- -------- ---- - -- ----- --------
27 0 PP OS 66 FASTPP
The basic device DEV TYPE remains PP, but device classes previously
associated with the device are replaced by the device class specified in
the MDEV command.
Saving Configuration Changes
To save changes in the configuration enter the following, starting from
the IO Configurator:
IO>HOLD
IO>EXIT
SYSGEN>KEEP
SYSGEN>EXIT
To make the changes effective, the system must be rebooted, which forces
a START NORECOVERY. For more information refer to System Startup,
Configuration and Shutdown Reference Manual (32650-90042)
NOTE Before rebooting the system, save or print all spoolfiles. If not,
they will be lost.
Configuring Pseudo Devices
SYSGEN allows the System Administrator to configure pseudo devices
logically. These devices do not have to be attached physically to the
system at the time. The feature lets you configure devices which will be
needed in the future, while physically attaching only those needed or
available now.
