Modifying Input/Output (I/O) Configurations
Using the SYSGEN I/O Configurator
You use the NMMGR program to add non-local devices such as terminals, serial printers,
UPS hardware and other objects to a system. To learn how to configure UPS devices, read
“Introducing the UPS and UPS Monitor/iX Software” later in this chapter. To learn how to
use NMMGR to configure other devices, read Configuring Systems for Terminals, Printers,
and Other Serial Devices.
Changing Configurations in SYSGEN
When you use SYSGEN to change the system configuration, there are five I/O Configurator
commands available: MADDRESS, MCLASS, MDEV, MPATH, and MVOL. They are defined in Table
ADEV Adds a device to an existing I/O path that is
configured to the device adapter level. At a
minimum, you must specify the LDEV, the path,
and ID number, butyou may also specify the record
size, an output device associated with the device,
the device operation mode, the class, a class mode
(other than the default assigned to the device),
physical and logical device managers, the priority
level of the physical device manager, the
compatability mode type and subtype, and a device
name.
ADEV LDEV=30 PATH=4.5.9
ID=HP2688A
ADEV 8 PATH=2/4.2.1
ID=HP7978B RSIZE=132
APATH Defines the I/O path to an adapter, not to a device.
(To add device level paths, you use the ADEV
command.) If the path has already been defined,
you will get an error. At a minimum, you must
enter the path and an ID, which is either the
Hewlett-Packard product number or a mnemonic
name that designates different uses of the same
product. You may also specify the physical and
logical device managers, the execution priority of
the physical device manager, and the maximum
number of concurrent I/Os to expect.
APATH PATH=4.2
ID=HP27113A
AVOL Adds a new volume to the system volume set
configuration. You must specify a unique name you
give to each volume member and its logical device
number. In addition, you may also specify the
volume class and the amounts of transient and
permanent disk space allocated on the volume.
AVOL VNAME=MEMBER2
LDEV=4 VCLASS=PROD
