218 RS/6000 43P 7043 Models 150 and 260 Handbook
When the installation of the backup has finished, the installation program
reconfigures the Object Data Manager (ODM) on the target system. If the
target system does not have exactly the same hardware configuration as the
source system, the program may modify device attributes in the following
target system files:
• All files in the /etc/objrepos file beginning with the letters CU
• All files in the /dev directory
The data restored from the mksysb-tape will only be the data from the rootvg
volume group. If you want to restore data from a non-root volume group you
have to run the restorevg command or use SMIT fastpath smit restvg.
Although the mksysb command will create a bootable tape on the PCI-based
RS/6000 servers, the tapes will not boot on Micro Channel-based
uni-processor or Micro Channel-based symmetric multiprocessor machines.
Additionally, mksysb tapes created on Micro Channel-based uni-processor and
Micro Channel-based symmetric multiprocessor machines will not boot on
PCI-based machines.
8.3.4 Cloning
This section also covers AIX 4.1 since there are many customers still using
AIX 4.1.
The term cloning describes the installation of a system backup (created with
the mksysb command on one system) on different systems in order to make
the software configuration of all systems as identical as possible. Using a
backup of one machine to install several other machines can be very useful
and will save the time taken to perform multiple installations.
8.3.4.1 Cloning on AIX 4.1
AIX 4.1 has been packaged so that only the devices that are needed are
actually installed on the system. This has made the cloning process difficult.
In AIX 4.1, the devices is separated from the base in separate filesets,
devices.* (such as devices.scsi.disk). This, coupled with all the new hardware
When cloning systems, please keep in mind that you will also clone IP
addresses. If both machines are connected to the network at the same
time, this will cause problems on the network. In this case, you have to
comment the tcpip entry in the /etc/inittab file.
