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

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. ______________________________________________________________ | | | | | io>LPATH | | | | PATH: 4 LDEV: | | ID: HP19744A TYPE: CA | | PMGR: SPECTRUM_CIO_CAM PMGRPRI: 6 | | LMGR: MAXIOS: 0 | | | | PATH: 4.1 LDEV: | | ID: HP27113A TYPE: DA | | PMGR: HPIB_DAM PMGRPRI: 6 | | LMGR: MAXIOS: 0 | | | | PATH: 4.1.0 LDEV: 1 | | ID: HP7937A TYPE: DISC | | PMGR: CS80_DISC_DM PMGRPRI: 8 | | LMGR: LOGICAL_DEVICE_MANAGER MAXIOS: 0 | | . | | . | | . | | PATH: 4.2 LDEV: | | ID: HP27140A TYPE: DA | | PMGR: TMUX_DAM_ME PMGRPRI: 6 | | LMGR: MAXIOS: 0 | | | | PATH: 4.2.0 LDEV: 20 | | ID: HP2392A TYPE: TERM | | PMGR: TMUX_DAM_ME PMGRPRI: 9 | | LMGR: LOGICAL_DEVICE_MANAGER MAXIOS: 0 | | | | . | | . | | . | | | ______________________________________________________________ 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. ______________________________________________________________ | | | | | io>LPATH MANAGER=CIPER_DM | | | | PATH: 4.5.4 LDEV: 6 | | ID: HP2566A TYPE: LP | | PMGR: CIPER_DM PMGRPRI: 10 | | LMGR: LOGICAL_DEVICE_MANAGER MAXIOS: 0 | | | ______________________________________________________________ Example 3-4.

Listing Paths: Series 950 through 980 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
