GROUP= configname
Default: GROUP =
CONFIG
When the system is booted with NORECOVERY, the group specified after
GROUP= is the source of configuration information. When performing an
UPDATE, INSTALL, or DUMP, this group is only in effect if START is
specified or defaulted. When a START command is entered, the group
specified (or defaulted) for it overrides any previous specification. Since
configuration groups reside in the SYS account, you do not specify the
account name.
LOGON= accountname
Default: LOGON=
OPERATOR.SYS
The logon account contains a standard logon. When the system is
booted, the account specified after LOGON= is used to initiate a session.
When SINGLE-USER has been specified, the account specified in LOGON=
is used as the single user. If LOGON= is not specified on the command
line, the logon defaults to OPERATOR.SYS (if the OPERATOR.SYS user
has been created).
RECOVERY or
NORECOVERY
During a START or an autoboot after a DUMP, this option indicates
whether or not restartable jobs are restarted. On DUMP, this option is in
effect only if START is specified or defaulted. If this option is not
specified, the default is RECOVERY. Note on an INSTALL or UPDATE, jobs
cannot be restarted, and the next START defaults to NORECOVERY.
Default: RECOVERY
(except with START
after INSTALL or
UPDATE)
Use NORECOVERY if the system configuration has changed. If RECOVERY is
specified and the system configuration has changed, the system
recovers restartable jobs by using the previous system configuration
and ignores the new system configuration and any GROUP= specification.
SINGLE-DISC or
MULTI-DISC
(Primarily Used for
Diagnostics)
Default: MULTI-DISC
This option determines whether or not the system initiates with all of
the volumes mounted (MULTI-DISC) or only the system master volume
mounted (SINGLE-DISC). If neither is specified, MULTI-DISC is the
default. SINGLE-DISC can be specified only if SINGLE-USER has also
been selected. If the SINGLE-DISC option is selected with MULTI-USER,
the system issues a warning message and changes the SINGLE-DISC
option to MULTI-DISC. If the START parameter is not specified or
defaulted on an INSTALL, UPDATE, or DUMP, the SINGLE-DISC parameter
is ignored.
SINGLE-USER or
MULTI-USER
(Primarily Used for
Diagnostics)
Default: MULTI-USER
This option boots the system with either single user capability or with
multiuser capability and all configured terminals available.
MULTI-USER is the default. SINGLE-USER is used primarily for diagnostic
support. For the INSTALL, UPDATE, and DUMP utilities, the
SINGLE-USER/MULTI-USER option is available only if START is specified
or defaulted as an option.
START or NOSTART
Default: START
This option instructs UPDATE, INSTALL, or DUMP whether or not to
autoboot (START) after the utility has completed its job. If neither START
nor NOSTART is specified, START is the default.
