Modifying Addresses, Classes, Devices, and Paths
The commands MADDRESS, MCLASS, MDEV, MPATH, and MVOL modify values
assigned to the system I/O configuration.
Modifying Addresses
The MADDRESS command (abbreviated MA) changes SYSGEN's view of the
physical location of channel adapters, device adapters, and devices.
MADDRESS has the following parameters:
MADDRESS (MA) [FROM =] device path
[TO =] device path
The FROM and TO parameters are standard I/O path specifications. If the
FROM path does not exist, or if both I/O paths do not have the same
number of levels, SYSGEN issues an error.
To change an existing I/O path to a new I/O path that is not configured,
enter
io>MADDRESS FROM=device path TO=devicepath
For example:
io>MADDRESS 4.1.2 4.1.3 ** Series 925/935 **
or
io>MADDRESS 2/4.0.2 6/4.0.3 ** Series 950/955 **
The TO address must first be configured to the device adapter level via
the APATH command.
All paths used in the MADDRESS command line must be at the same level.
Modifying Classes
The MCLASS command changes I/O class information including class mode,
class name, and the devices associated with the class.
MCLASS has the following parameters:
MCLASS (MC) [CLASS =] classname
[ [NEWCLASS =] newclassname]
[ [ALDDEV =] logical device #,...]
[ [DLDEV =] logical device #,...]
[ [MODE =] IN ]
[ OUT ]
[ CIO ]
[ NCIO ]
[ RANDOM ]
[ DEFAULT ]
Enter the class name for which one or more attributes are to be changed
and enter at least one additional parameter for a modification:
io>MCLASS classname newclassname MODE=OUT
io>MCLASS classname1,classname2, logical device #1/logical device #2
The first line above changes the class name from classname to
newclassname and specifies newclassname as an output device. The second
line adds logical devices logical device #1 and logical device # 2 from
the classname1 class to the classname2 class.
Modifying Devices
The MDEV command (abbreviated MD) modifies the attributes of a given
device. Although only the first parameter is required, at least one
other parameter must be specified for each command. MDEV has the
following parameters:
MDEV (MD) [LDEV =] device range
[ [NEWLDEV =] device range]
[ [ID =] product id]
[ [PATH =] I/O path]
[ [CLASS =] class name]
[ [MODE =] JOB ]
[ DATA ]
[ INTERACTIVE ]
[ DUPLICATIVE ]
[ INPUT ]
[ OUTPUT ]
[ AUTOREPLY ]
[ NLIO ]
[ NONE ]
[ [OUTDEV =] output device]
[ [RSIZE =] device record size]
[ [PMGR =] physical manager name]
[ [LMGR =] logical manager name]
[ [PMGRPRI =] physical manager priority]
[ [MPETYPE =] compatibility mode type]
[ [MPESUBTYPE =] compatibility mode subtype]
[ [DEVNAME =] device name]
You may also use the MDEV command to change the attributes associated
with assigned LDEV. Enter the LDEV number to be modified and at least one
other parameter for a change to be made. For example:
io>MDEV 8 18 HP7978H 4.3.0 MODE=JOB
Modifying I/O Paths
The MPATH command (abbreviated MP) modifies the attributes associated
with an I/O path. MPATH has the following parameters:
MPATH (MP) [PATH =] I/O path]
[ [ID =] product-id]
[ [PMGR =] manager-name]
[ [LMGR =] manager-name]
[ [PMGRPRI =] manager-priority]
[ [MAXIOS =] maximum expected concurrent channel I/Os]
Enter the I/O path number to make the appropriate attribute changes and
enter at least one parameter to be changed. For example:
io>MPATH 2/4.3 HP27113 ** Series 950/955 **
Changing the product identification parameter to an HP-IB adapter for the
4.3 I/O path changes all other parameters that reference the SYSGEN I/O
default file. To override any default changes, enter the corresponding
parameter and information:
io>MP 4.1 PMGR=HPIB_DAM ** Series 925/935 **
or
io>MPATH 2/4.3 PMGR=HPIB_DAM ** Series 950/955 **
Modifying Volumes
The MVOL command (abbreviated MV) is reserved for use by Hewlett-Packard
Service Personnel only.
