Getting Information from the I/O Configurator
Use the IO configurator to display information about your system
configuration including paths, volumes, class names, logical device names
and logical device numbers (LDEVs). Once you know the current
configuration, you can make any necessary changes.
There are two kinds of information you can get once you have started the
IO configurator:
* helpful information about any of the IO configurator commands
* information about the current configuration, either displayed on
screen or printed, using the LCLASS, LDEV, LPATH, and LVOLcommands
--------------------------------------------------------------------------------------------
| | |
| Command | Definition |
| | |
--------------------------------------------------------------------------------------------
| | |
| LCLASS | Lists the specified class names and the devices assigned to each |
| | one. |
| | |
--------------------------------------------------------------------------------------------
| | |
| LDEV | Lists the attributes of the specified logical devices. |
| | |
--------------------------------------------------------------------------------------------
| | |
| LPATH | Lists the attributes of the specified paths. |
| | |
--------------------------------------------------------------------------------------------
| | |
| LVOL | Lists the attributes of the specified volume set member. |
| | |
--------------------------------------------------------------------------------------------
To access the IO configurator
You make all changes to the I/O configuration from within the IO
configurator, which is one of the SYSGEN modules. To access the IO
configurator, do the following:
1. At the MPE prompt, start SYSGEN by entering:
:SYSGEN
2. At the SYSGEN prompt (sysgen>), enter:
sysgen>IO
When you first access the IO configurator, you see a list of the commands
available to you. To issue a command, you can enter either the full
command name or the abbreviation shown in parentheses.

Example 3-1. Entering the IO Configurator
To use online help
You can display helpful information about any of the IO configurator
commands on the screen. To do so, enter the HELP command at the io>
prompt in one of two forms:
* To get help for a specific command, type HELP and then the command
name. For example, to display a description, the syntax, and
examples of the APATH command, enter:
io>HELP APATH
* To see a list of all the IO configurator commands with a brief
description of each one, simply enter HELP or H.
To list classes
A class name is an identifier to which numerous devices can be assigned.
Unlike logical device numbers, device class names are not unique to each
device. For example, all of your system's printers could be assigned the
class name LP, which stands for "line printer."
To list a class name, at the IO configurator prompt (io>), enter:
io>LCLASS parameters
LCLASS has the following parameters:
LCLASS (LC) [[CLASS =] classname] [[DEST =] OFFLINE]
To list all classes.
To list all class names, class modes, and the devices associated with the
classes in the I/O configuration, enter:
io>LCLASS
Example 3-2 shows you the kind of output you will see.

Example 3-2. Listing System Classes
To list specific classes.
To list the logical devices (LDEVs) that belong to a particular device
class, enter LCLASS classname at the IO configurator prompt. For
example, to see all LDEVs in the device class DISC, enter:
io>LCLASS DISC
To list multiple classes.
To list multiple classes, enclose each class name in parentheses and
separate them with commas. For example, to list the assigned LDEV
numbers of combined classes DISC and LP, enter:
io>LCLASS (DISC,LP)
To list devices
Each configured logical device (LDEV) is assigned a unique LDEV number.
The LDEV number identifies a physical device associated with a system.
Use the LDEV command (abbreviated LD) to list the characteristics of the
I/O devices configured for your system. You can list all devices, a
subset of them, or a specific device.
To list the devices on your system, at the IO configurator prompt (io>),
enter:
io>LDEV parameters
The LDEV command has the following parameters:
LDEV (LD) [[LDEV =] devicerange] [[ID =] productnumber]
[[TYPE =] devicetype] [[CLASS =] classname,...] [[DEST =] OFFLINE]
To list all devices.
To list the characteristics of all of the I/O devices currently
configured, enter the LDEV command without any parameters. For example:
io>LDEV
To list specific devices.
To list specific devices, enter the LDEV parameter followed by the number
or numbers of the devices you want to see. For example, to list LDEV 38
and LDEV 39, enter:
io>LDEV LDEV=38,39
To list a range of devices.
You can list a range of devices by entering the first device number and
the last device number separated by a slash. For example, to list
devices 4 through 9, enter:
io>LDEV 4/9
To list a nonconsecutive range of devices, separate each range with a
command and enclose them in parentheses. For example:
io>LDEV (4/9,11/14)
To list multiple devices.
You can list all devices within a particular class or a set of classes.
For example, to list all line printers (the class LP) and disk drives
(the class DISC) on your system, enter:
io>LDEV CLASS=(LP,DISC)
To list devices by product identification number.
To list all devices on your system that have a particular product ID, use
the ID parameter and the product number. For example:
io>LDEV ID=HP2566A
To list devices by type.
To list all devices of a particular type, use the TYPE parameter and the
type name. For example, to see DISC devices, enter:
io>LDEV TYPE=DISC
NOTE SYSGEN displays only the LDEV number for NMMGR devices. An
asterisk (*) after the LDEV number means the path conflicts with
NMMGR. Refer to System Startup, Configuration, and Shutdown
Reference Manual (32650-90042) for more information on conflicts
between NMMGR and SYSGEN.
To list paths
Use the LPATH command to display information about the adapters and I/O
devices on a specified path level. LPATH lists the configured I/O paths
according to their path, hierarchy level, or associated I/O manager.
To display I/O path information, at the IO configurator prompt (io>),
enter:
io>LPATH parameters
LPATH has the following parameters:
LPATH (LP) [[PATH =] path] [[LEVEL =] #] [[MANAGER =] managername,...]
[[DEST =] OFFLINE]
To list all paths.
Enter LPATH without any parameters to display all configured paths:
io>LPATH
You will see all of the device-dependent information associated with a
given I/O path which includes:
* the ID of the device assigned to that path level
* the logical and physical manager names
* the device type
Example 3-3 shows you output from the LPATH command for Series 925
through 949 systems and a Series 958 system.

Example 3-3. Sample LPATH Display
To list a specific path.
To list information for a specific path use the PATH parameter followed
by the path number. For example, to see path 4, enter:
io>LPATH PATH=4
NOTE If you are using a Series 950 through Series 980 system, you must
use a slash (/) to separate the bus converter number from the rest
of the path identification. Otherwise, SYSGEN issues a message.
**warning** The correct delimiter at this level is a "/"
Path (up to this level) changed to 6/
To list level paths.
Use the LEVEL parameter to list I/O paths at a given level. The LEVEL
parameter, when assigned a value, displays the devices at that level.
For example, to see the devices at level1, enter:
io>LPATH,1
NOTE To list the I/O channel adapters on Series 925 through Series 949
systems and Series 958 systems and the bus converters on Series 950
through Series 980 systems, use LPATH,1.
Table 3-1 shows the level and the information it displays for
midrange systems (HP 3000 Series 925 through Series 949 systems, and
Series 958 systems) and for high-end systems (Series 950 through Series
980 systems).
Table 3-1. Paths Displayed by Levels
----------------------------------------------------
| | | |
| Level | Series 925-949, | Series 950-980 |
| | 958 | |
| | | |
----------------------------------------------------
| | | |
| 1 | channel adapter | bus converter |
| | | |
----------------------------------------------------
| | | |
| 2 | device adapter | channel adapter |
| | | |
----------------------------------------------------
| | | |
| 3 | device | device adapter |
| | | |
----------------------------------------------------
| | | |
| 4 | | device |
| | | |
----------------------------------------------------
The level number used in the LEVEL parameter corresponds to the number of
delimited digits in the path displayed. For the Series 950 through
Series 980 systems, the path 6/4.3.0 has 6 as the bus converter, 4 as the
channel adapter, 3 as the device adapter, and 0 as the device. For the
Series 925 through Series 949 systems, the path 4.2.0 has 4 as the
channel adapter, 2 as the device adapter, and 0 as the device.
If you are working with a Series 922 or Series 932 system, including the
LX and RX models, refer to HP 3000 Series 922 Family Computer
Systems/Operator Hand book (A1027-90019).
To list a manager's path.
To list the I/O paths associated with a specific device manager under the
heading PMGR or LMGR, use the MANAGER parameter. For example:
io>LPATH MANAGER=CIPER_DM
If the manager you specify in the LPATH command doesn't exist, SYSGEN
issues a warning.
The examples below shows the output from this command for some midrange
and high-end systems.

To list volumes
A volume is one disk pack. Each volume is a member of a volume set and
contains a volume label, a label table, and a free space map. To list
volumes, at the IO configurator prompt (io>), enter:
io>LVOL
LVOL has the following parameters:
LVOL (LV) [[VNAME =] volumename,[volumename][...]] [[DEST =] ``OFFLINE'']
To list all volumes.
To list volume information for all volumes, enter the LVOL command
without any parameters. For example:
io>LVOL
To list a specific volume.
To list information about a member volume, enter LVOL with the volume
name. SYSGEN displays the LDEV number of each device, the amount of
transient and permanent space, the class status, and the volume class.
For example, to see information about the volume MEMBER1, enter
io>LVOL MEMBER1
To print configuration information
Each of the commands that you use to list configuration information has a
DEST=OFFLINE parameter that allows you to print the information instead
of displaying it on the console. This parameter is useful when you need
to compare one configuration to another or, for example, when you want to
enclose a printed copy of the configuration with the system load tape
(SLT).
To print configuration data, enter one of the list commands (LCLASS,
LDEV, LPATH or LVOL), any additional parameters you need, followed by the
parameter OFFLINE. This sends the listing to the file SYSGLIST. To close
and print the list, you use the OCLOSE command or exit the IO
configurator.
For example, to print information about all devices with device class
DISC and LP on your system, do the following:
1. At the IO configurator prompt (>io) enter:
io>LCLASS (DISC,LP) DEST=OFFLINE
Or, you can enter the command this way:
io>LCLASS (DISC,LP) OFFLINE
2. To close the file SYSGLIST and print the information, enter
io>OCLOSE
