A    Definitions of Installation CDF Attribute-Value Pairs

The attribute-value pairs within individual items differ as a result of the distribution method (CD-ROM or RIS) that was used to perform the initial Full Installation of the model system. This appendix describes the contents of the following items in the install.cdf file:

• Inst_islinfo

• Inst_filesystem

• Inst_disklabel

• Inst_lsm_global

• Inst_lsm_disks

• Inst_subsets

• Inst_cinstall

Caution

Only experienced system administrators should modify the attributes-value pairs in the install.cdf file. Typographical errors and inserting attribute-value pairs into the incorrect item may result in serious corruption on the cloned system and may render the system unusable.

In addition, attribute-value pairs cannot contain blank spaces because blank spaces cause data validation errors. Be very careful to remove all blank spaces especially at the end of a line. When you want to give an attribute a null value, make sure there is nothing (null) after the equal sign ( = ).

Do not modify or remove attributes that are prefixed with an underscore ( _ ). These attributes, for example _action=create, are internal variables required by the Full Installation and Installation Cloning processes.

A.1    Attributes in the Inst_islinfo Item

Table A-1 defines the attributes in the Inst_islinfo item in the CDF. The Inst_islinfo item is used to convey the system state before the start of the installation process.

A.2    Attributes in the Inst_filesystem Item

Table A-2 defines the attributes in the Inst_filesystem item in the CDF. The Inst_filesystem item conveys information about the number and type of file systems that are to be created on the cloned system. At a minimum, there must be at least four file system items to describe the /, /usr, and /var file systems and one swap area. Except where noted, you can modify all attribute-value pairs in this item, although it is not recommended.

A.3    Attributes in the Inst_disklabel Item

Table A-3 defines the attributes in the Inst_disklabel item in the CDF. The Inst_disklabel item conveys the size and offset of each partition to be created on the cloned system. An Inst_disklabel item is created for each disk on which you installed a file system or swap area. For example, if you installed / on dsk0, and /usr on dsk1, an Inst_disklabel item will be created for dsk0 and dsk1. All other disks on the target system will be unaffected during cloning.

A.4    Attributes in the Inst_lsm_global Item

Table A-4 defines the attributes in the Inst_lsm_global item in the CDF. The Inst_lsm_global item conveys the size of the Logical Storage Manager (LSM) private region to be created on all configured disks and defines an LSM host name. The Inst_lsm_global item is created only if you chose to install into LSM volumes.

A.5    Attributes in the Inst_lsm_disks Item

Table A-5 defines the attributes in the Inst_lsm_disks item in the CDF. The Inst_lsm_disks item conveys the private region partition and disk information. An Inst_lsm_disks attribute is created for each configured disk. The Inst_lsm_disks item is created only if you chose to use LSM.

A.6    Attributes in the Inst_subsets Item

Table A-6 defines the attributes in the Inst_subsets item in the CDF. The Inst_subsets item is used to convey information to the Installation Cloning process about the base operating system software subsets that are to be installed on the system to be cloned. One Inst_subsets item always will exist for the base operating system software. There can be up to two additional Inst_subsets items for WLS software.

A.7    Attributes in the Inst_cinstall Item

Table A-7 defines the attributes in the Inst_cinstall item in the CDF. The Inst_cinstall item is used to convey target system configuration information to the Installation Cloning process. All of the attributes specified in the installation configuration item are optional. If values are not provided for these attributes, the installation process becomes interactive to request this information during the system configuration phase.

To use a single CDF to clone many systems, consider leaving the system-specific attributes such as host name and password null, but provide attributes for site-specific attributes such as kernel option, time zone, geographic location, and date and time.
