LOGON authorization checking for the user ID. The BYUSER must be listed on
a LOGONBY statement in the directory entry for the user ID to use the BY
operand. Refer to usage note 14 on page 582 for information on External
Security Manager (ESM) considerations.
Ipl vdev
Ipl sysname
specifies the virtual device number or named saved system that you want IPLed
upon completion of your logon processing. This option overrides the IPL
statement (if any) specified in your entry in the system directory. The validity of
the IPL operand you specify is determined by the IPL command processor after
your logon is completed; it is not verified as part of the LOGON command
processing.
NOipl
specifies that the IPL device specified in your entry in the system directory
should not be used for an automatic IPL.
LOGON
MACHine ESA
MACHine XA
MACHine XC
specifies the mode (architecture) of the virtual machine. This option overrides
the MACHINE statement (if any) specified in your entry in the system directory.
For further information on the MACHINE directory control statement, see z/VM:
CP Planning and Administration.
ESA designates ESA/390 (31-bit) architecture. A guest operating system may
have the capability to issue an instruction to switch an ESA virtual machine to
z/Architecture (64-bit) mode. XA is supported for compatibility and is functionally
equivalent to ESA. XC designates ESA/XC architecture.
NORUN
specifies that upon successful completion of the user logon, the virtual machine
is placed in a terminal CP READ state, and RUN is set OFF.
QUIET
suppresses the display of all informational LINK messages, system log
messages, and information regarding spooled virtual reader, printer, and punch
files.
SEClabel ssssssss
specifies that the user is requesting to logon with a specific security label,
identified by ssssssss. ssssssss is specified as a 1-character to 8-character
alphanumeric value. This operand is valid only when an ESM is installed and
security label checking is enabled. For additional information, contact your
security administrator.
Storage nu
specifies an alternate storage size to be assigned to your virtual machine. The
storage size is specified in the form nu, where n is a decimal number and u is
the unit of measure:
