8.3.4 Using the rmfs
A mksysb images enable you to clone one system image onto multiple target systems. The target systems might not contain the same hardware devices or adapters, require the same kernel (uniprocessor or microprocessor), or be the same hardware platform (rs6k, rspc, or chrp) as the source system. If you are installing a mksysb on a system it was not created on, use the procedure Cloning Your System.
Use this procedure to install a mksysb on a target system it was not created on. Be sure to boot from the product media appropriate for your system and at the same maintenance level of BOS as the installed source system that the mksysb was made on. For example, you can use BOS Version 4.2.1 product media with a mksysb from a BOS Version 4.2.1 system. This procedure is to be used when installing a backup tape to a different system.
After booting from product media, complete the following steps when the Welcome to the Base Operating System Installation and Maintenance screen is displayed.
You will be prompted again for the BOS installation language, and the Welcome screen should be displayed. Continue with the Prompted
Installation, as cloning is not supported in nonprompted installations.
After the mksysb installation completes, the installation program automatically installs additional devices and the kernel (uniprocessor or microprocessor) on your system using the original product media you booted from. Information is saved in BOS installation log files. To view BOS installation log files, enter cd /var/adm/ras and view the devinst.log file in this directory.
If the source system does not have the correct passwords and network information, you may make modifications on the target system now. Also, some products ship device-specific files such as graPHIGS. If your graphics adapter is different on the target system, verify that the device-specific filesets for graphics-related LPPs are installed.
If the system you have cloned is using OpenGL or graPHIGS, there may be some device filesets from these LPPs that must be installed after a clone.
