Adding Classes, Devices, and Paths
There are four user commands (ACLASS, ADEV, APATH, and AVOL) within the
I/O configurator that add objects to the system.
Adding Classes
The ACLASS command adds a class name designation to an existing
(configured) device. You must add the device path and designate the LDEV
number before adding the class designation.
ACLASS has the following parameters:
ACLASS (AC) [CLASS =] classname
[LDEV =] device range
[ [MODE =] IN ]
[ OUT ]
[ CIO ]
[ NCIO ]
[ RANDOM ]
[ DEFAULT ]
Classname is a standard MPE XL class name of up to eight characters, such
as EPOC or SPOOL. If the specified class name already exists when you
attempt to add it, SYSGEN issues an error message.
To add a class, enter the ACLASS command, the class name, and the LDEV
associated with it:
io>ACLASS classname devicerange
If you do not assign the device a mode, SYSGEN assigns it a default mode.
To add the mode to the information, enter the ACLASS command and use the
keyword or positional MODE parameter. For example:
io>ACLASS PLATES 31/34 MODE=RANDOM ** keyword **
io>ACLASS PLATES 31/34 RANDOM ** positional **
Adding Devices
(System master volume must be mounted on LDEV 1 for the operating system
to be booted from disk and LDEV 20 must be assigned to the system
console.)
The ADEV command (abbreviated AD) adds a device to an existing I/O path,
which is configured to the device adapter level.
ADEV has the following parameters:
ADEV (AD) [LDEV =] device range
[ [PATH =] I/O path
[ [ID =] product id/USER
[ [RSIZE =] record size]
[ [OUTDEV =] output device]
[ [MODE =] JOB ]
[ DATA ]
[ INTERACTIVE ]
[ DUPLICATIVE ]
[ INPUT ]
[ OUTPUT ]
[ AUTOREPLY ]
[ NLIO ]
[ NONE ]
[ [CLASS =] classname,... ]
[ [CMODE =] IN ]
[ OUT ]
[ CIO ]
[ NCIO ]
[ RANDOM ]
[ DEFAULT ]
[ [PMGR =] physical manager name]
[ [LMGR =] logical manager name]
[ [PMGRPRI =] physical manager priority]
[ [MPETYPE =] compatibility Mode type]
[ [MPESUBTYPE =] compatibility Mode subtype]
[ [DEVNAME =] device name]
MPETYPE and MPESUBTYPE specify values for compatibility mode type and
subtype. Those values are not allowed for all Hewlett-Packard devices
which get their values from IODFAULT.PUB.SYS.
When using the ADEV command, you must specify, at a minimum, the LDEV,
path, and ID number. Use either the keyword or positional parameter.
For the Series 925/935, for example:
io>ADEV LDEV=30 PATH=4.5.9 ID=HP2688A ** Keyword **
io>ADEV 30,4.5.9, HP2688A ** Positional **
or for the Series 950/955:
io>ADEV LDEV=40 PATH=2/8.1.4 ID=HP7935H ** Keyword **
io>ADEV 40, 2/8.1.4, HP7935H ** Positional **
If you add an unsupported device, enter the ID parameter as "USER" and
supply the information for all other parameters:
io>AD 40, 36.1.4, USER 132 10 OUTPUT LP DEFAULT&
USER_PHYS_MGR USER_LOGICAL_MANAGER PMGRPRI=8&
MPETYPE=value MPESUBTYPE=value
Most devices have a default device mode. The mode NONE is useful for
overriding a default. The default modes for devices are contained in the
IODFAULT file, an ASCII file that can be displayed.
SYSGEN also uses a "maximum mode." Certain devices can have one or more
modes only. The remaining modes are not permitted. For example, an
HP7978 tape drive can have the following modes: JOB, DATA, INPUT,
OUTPUT, AUTOREPLY, and NONE.
If you assign an improper mode to a device, SYSGEN issues an error
message:
io>ADEV 40 36.0.7 HP2688 MODE=AUTOREPLY
**error** illegal device mode for this device
A printer cannot be assigned the device mode AUTOREPLY.
Adding Paths
The APATH command adds an I/O path (at the channel or device adapter
level) to the system configuration. Add device level paths with the ADEV
command. The device path is channel adapter, module number, device
adapter.
APATH has the following parameters:
APATH (AP) [PATH =] device path
[ID =] product id
[ [PMGR =] physical manager name]
[ [LMGR =] logical manager name]
[ [PMGRPRI =] physical manager priority]
[ [MAXIOS =] max. expected concurrent channel I/Os]
To add a path that has not been configured, enter APATH, the path, and
the product ID:
io>APATH 4.2 HP27113 ** Series 925/935 **
or
io>APATH 2/8.2 HP27113 ** Series 950/955 **
The example adds an HP-IB Device Adapter to the 4.2, 8.2 or 2/8.2 I/O
path.
SYSGEN supplies the remaining information from the I/O default file,
IODFAULT. If the device is an unsupported Hewlett-Packard device, enter
the remaining parameters with the APATH command.
Adding Volumes
The AVOL command is reserved for use by Hewlett Packard Service Personnel
only. Do not use this command.
