Editor's Notes
- #3 If you are overwriting an existing system, gather the TCP/IP information from the system before you begin this scenario. Attention: This procedure requires shutting down and reinstalling the base operating system. Whenever you reinstall any operating system, schedule your downtime when it least impacts your workload to protect yourself from a possible loss of data or functionality. Before you perform a new and complete overwrite installation, ensure you have reliable backups of your data and any customized applications or volume groups. For instructions on how to create a system backup, refer to Creating system backups
- #4 Make sure your hardware installation is complete, including all external devices. See the documentation provided with your system unit for installation instructions. Make sure you have that information your system needs to communicate with other systems and access their resources, before proceeding:
- #5 Make sure your hardware installation is complete, including all external devices. See the documentation provided with your system unit for installation instructions. Make sure you have that information your system needs to communicate with other systems and access their resources, before proceeding:
- #6 Make sure all external devices attached to the system (such as DVD drives, and terminals) are turned on. Only the media drive from which you will install AIX should contain the installation media. If you have a graphics display, you will see the keyboard icon on the screen when the beeps occur. If you have an ASCII terminal (also called a tty terminal), you will see the word keyboard when the beeps occur. Note: If your system does not boot using the F5 key (or the 5 key on an ASCII terminal), refer to your hardware documentation for information about how to boot your system from an AIX product media. Select English language for the base operating system (BOS) Installation menus by typing a 1 in the Choice field
- #8 Use any other options at this time. You can return to the Configuration Assistant or the Installation Assistant by typing configassist or smitty assist at the command line. If you are in the Configuration Assistant, select Finish now , and do not start Configuration Assistant when restarting AIX and select Finish.
- #9 Attention: This procedure requires shutting down and reinstalling the base operating system. Whenever you reinstall any operating system, schedule your downtime when it least impacts your workload to protect yourself from a possible loss of data or functionality. Before you perform a migration installation, ensure you have reliable backups of your data and any customized applications or volume groups. For nstructions on how to create a system backup, refer to Creating system backups in AIX Version 7.1 Installation and migration. Before you begin the installation, other users who have access to your system must be logged off. Verify that your applications will run on AIX Version 7.1. Also, check if your applications are binary-compatible with AIX Version 7.1. If your system is an application server, verify that there are no licensing issues. Refer to your application documentation or provider to verify on which levels of AIX your applications are supported and licensed. You can also check the Supported : http://www-03.ibm.com/services/sl/products/ Note: Do not remove the data created by the pre_migration script, because it is used by the post_migration script. . For instructions on how to create a system backup, refer to Creating system backups. Always refer to the release notes for the latest migration information.
- #10 Verify that the selections are correct in the Overwrite Installation Summary screen, as follows: Overwrite Installation Summary Disks: hdisk0 Cultural Convention: en_US Language: en_US Keyboard: en_US JFS2 File Systems Created: Yes Graphics Software: Yes Desktop: CDE System Management Client Software: Yes Enable System Backups to install any system: Yes Optional Software being installed: >>> 1 Continue with Install 88 Help ? 99 Previous Menu >>> Choice [1]:
- #11 Make sure all external devices attached to the system (such as DVD drives, and terminals) are turned on. Only the media drive from which you will install AIX should contain the installation media. If you have a graphics display, you will see the keyboard icon on the screen when the beeps occur. If you have an ASCII terminal (also called a tty terminal), you will see the word keyboard when the beeps occur. Note: If your system does not boot using the F5 key (or the 5 key on an ASCII terminal), refer to your hardware documentation for information about how to boot your system from an AIX product media. Select English language for the base operating system (BOS) Installation menus by typing a 1 in the Choice field Note: Do not remove the data created by the pre_migration script, because it is used by the post_migration script.
- #12 To use the Help menu to learn more about the options available during a migration installation, type 88 and press Enter in the Installation Options menu. For more information about the install ation options available in AIX Version 7.1, see BOS installation options.
- #13 For more information on the Configuration Assistant or the Installation Assistant, see Configuring AIX with the Configuration Assistant. Use any other options at this time. You can return to the Configuration Assistant or the Installation Assistant by typing configassist or smitty assist at the command line.
- #14 . Consider altering passwords and network addresses if you use a backup to make master copies of a source system. Copying passwords from the source to a target system can create security problems. Also, if network addresses are copied to a target system, duplicate addresses can disrupt network communications. use the mount coomand to Mount all file systems to back up. The mksysb command backs up only mounted JFS and JFS2 in rootvg . The mksysb command does not back up file systems mounted across an NFS network. Unmount any local directories that are mounted over another local directory, if you mount /tmp over /usr/tmp, the files in the /tmp directory are then backed up twice. Use the /etc/exclude.rootvg for files you do not want backed up.
- #15 Note: If you plan to reinstall the backup to target systems other than the source system, or if the disk configuration of the source system might change before reinstalling the backup, do not create map files. Select yes in the Create Map Files, Exclude Files, List files as they are backed up , and Disable software packing of backup. Use the default values for the rest of the menu options. The COMMAND STATUS screen displays, showing status messages while the system makes the backup image. When the backup process finishes, the COMMAND: field changes to OK. Because the system backup contains a boot image, you can use this tape to start your system if for some reason you cannot boot from hard disks.
