sysman_clone(8)sysman_clone(8)NAMEsysman_clone - Saves SysMan configuration information, which can be
used to clone configurations on similar systems
SYNOPSIS
/usr/sbin/sysman -clone
/usr/sbin/sysman -clone -apply [file]
/usr/sbin/sysman -clone -help
/usr/sbin/sysman -clone -list
/usr/sbin/sysman -clone -save [file]
/usr/sbin/sysman -clone -validate [file]
OPTIONS
The file argument is optional and specifies an alternate path to the
configuration description file (CDF). The default path and file name
is var/adm/smlogs/config.cdf. Applies the configuration information
specified in the /var/adm/smlogs/config.cdf file. If the optional file
parameter is specified, this parameter specifies a CDF file in an
alternate location. When performing an apply operation, the CDF auto‐
matically is validated prior to the actual apply operation. Displays
command usage information for the sysman(8) command. Lists the current
values for all configured SysMan components/groups supported by sysman
-clone. Saves the current values for all configured SysMan compo‐
nents/groups supported by sysman -clone to the /var/adm/smlogs/con‐
fig.cdf file. If the optional file parameter is specified, compo‐
nent/group information is saved to the specified file instead of
/var/adm/smlogs/config.cdf. Validates the file /var/adm/smlogs/con‐
fig.cdf, or the file specified by the optional file parameter. The
validation pass consists of invoking each component's built-in valida‐
tion routine and the checksum number at the top of the file.
OPERANDS
Specifies an alternate Configuration Description File (CDF).
DESCRIPTION
The sysman -clone command provides the ability to save certain SysMan
configuration information from a previously configured system and
duplicate that configuration information to one or more systems with a
similar hardware configuration. The configuration information is saved
to a text-based Configuration Description File (CDF). The CDF is orga‐
nized as a pseudo stanza(4) file, with a hierarchical listing of compo‐
nents, groups, and attribute-value pairs describing the configuration
of various components of a system.
It is recommended that you use the sysman(8) command to accesssysman
-clone functions.
The following components can be cloned: Domain Name Service (DNS)
client setup DOP actions and privileges Internet services Mail client
setup Network File System (NFS) Network interface Network Time Protocol
(NTP) Network Information Service (NIS) Printer setup
Supported components and groups, as well as their current values, can
be queried through the use of the -list option. For descriptions of
each component, group, and attribute, and how it affects the configured
system, refer to the sysman_cli(8) command.
The config.cdf file is particularly useful during a Full Installation
of the operating system to provide an automated and unattended system
configuration. Combining this ability with an Installation Cloning pro‐
vides for an efficient way to install and configure multiple systems in
a non-interactive fashion. The Full Installation process searches for
the installation CDF (named install.cdf) and the configuration CDF in
these locations in the order shown: Diskette drive Remote Installation
Services (RIS) directory CD-ROM drive The /var/tmp directory
The Installation Guide -- Advanced Topics provides detailed information
about Installation Cloning, Configuration Cloning, the placement of
CDFs, and writing user-supplied scripts to dynamically modify CDFs. The
Full Installation process always searches for CDFs at predefined points
in the process. If a CDF is found in any of the supported locations, it
will be applied automatically to install, configure, or install and
configure the target system.
Generating Unique Client Configurations
When saving the configuration of a model system with the intention of
applying the configuration to multiple target systems, there are sev‐
eral host-specific attributes that you need to modify to allow each
target system to be uniquely identified on a network. The specific
host-specific attributes that must be modified are: The unique name of
the system as it is known on a network. This attribute is located in
the netconfig component in the interface group, and depending upon
which other components are configured, the host name may be specified
in other attributes. Make sure to search for and change all instances
of host name. The unique internet protocol address of the system as it
is identified on a network. This attribute is located in the netconfig
component in the interface and host groups. The network adapter
attached to the system. This value is modified only if the network
adapter on the system to be cloned is different from the one defined in
the config.cdf file. Valid values for this attribute include tu0 for
Tulip devices, ln0 for Lance devices, and fddi0 for FDDI devices.
To facilitate configuration cloning of multiple target systems, it is
suggested that you create a single template or representative CDF with
the values of these host-specific attributes set to dummy variables.
You can then manually enter a value for the dummy variables before
applying them to a target system, or you can create a user-supplied
script, which is invoked during a Full Installation to dynamically mod‐
ify a config.cdf file before it is applied to the system. This proce‐
dure is documented in the Installation Guide -- Advanced Topics.
The Global Attribute CDFMODE
During the application of configuration information to a client system,
it is possible to specify how the values of databases with multiple
records (for example, entries in /etc/hosts or /etc/printcap) should be
applied to the system. The CDFMODE attribute is a global CDF attribute
that can be specified manually and placed outside of any component con‐
tained within the CDF file. The CDFMODE attribute only affects data‐
bases with multiple records; individual component/group data always
will be overwritten by the new value specified in the CDF. Once a CDF‐
MODE has been specified in a CDF, that value is in effect until another
CDFMODE statement is encountered, or the apply process completes.
There are three values associated with the CDFMODE attribute: Merges
the component/group data that exists in the CDF with the data that is
currently configured on the system. Using the merge functionality, rows
of records that are duplicated between the CDF and the configured sys‐
tem are ignored. MERGE is the default behavior and is implied for the
entire CDF if CDFMODE is not specified. Appends component/group data
that exists in the CDF to the configured system. Duplicate entries that
exist between the CDF and the configured system will not be ignored.
Replaces component/group data that exists on the system with the data
specified in the CDF. Data existing on the configured system but not
in the CDF will be removed. Data that exists in the CDF, but not on
the configured system, will be applied. Data that exists in the CDF, as
well as the configured system, will be modified accordingly.
RESTRICTIONS
You must be a privileged user to use this command.
Configuration cloning is not supported in a cluster.
EXAMPLES
The following example lists to stdout the components, groups, and
attribute-value pairs for the supported SysMan clonable configuration
data. # sysman -clone -list The following example saves SysMan config‐
uration data to a CDF named template.cdf in the /admin directory. #
sysman -clone -save /admin/template.cdf The following example manually
applies the saved configuration information specified in
/var/adm/smlogs/config.cdf to the target system. The config.cdf file
must be located in the /var/adm/smlogs directory of the system to be
cloned. # sysman -clone -apply The following example uses the CDFMODE
global attribute to specify that all entries in the /etc/hosts file
should be replaced by the data specified in the hostmappings group.
The CDFMODE
attribute is then reset to merge for the rest of the apply
process.
