Creating a root volume group backup on CD or DVD with the ISO9660 format

Edit online

Follow this procedure to create a root volume group backup on CD or DVD with the ISO9660 format.

You can use SMIT to create a root volume group backup on CD or DVD with the ISO9660 format, as follows:
  • To create a backup to CD, use the smit mkcd fast path.
  • To create a backup to DVD, use the smit mkdvd fast path and select ISO9660 (CD format).
The following procedure shows you how to use SMIT to create a system backup to CD. (The SMIT procedure for creating a system backup to an ISO9660 DVD is similar to the CD procedure.)
  1. Type the smit mkcd fast path. The system asks whether you are using an existing mksysb image.
  2. Type the name of the CD-R device. (This can be left blank if the Create the CD now? field is set to no.)
  3. If you are creating a mksysb image, select yes or no for the mksysb creation options, Create map files? and Exclude files?. Verify the selections, or change as appropriate.

    The mkcd command always calls the mksysb command with the flags to extend /tmp.

    You can specify an existing image.data file or supply a user-defined image.data file. See step 16.

  4. Enter the file system in which to store the mksysb image. This can be a file system that you created in the rootvg, in another volume group, or in NFS-mounted file systems with read-write access. If this field is left blank, the mkcd command creates the file system, if the file system does not exist, and removes it when the command completes.
  5. Enter the file systems in which to store the CD or DVD file structure and final CD or DVD images. These can be file systems you created in the rootvg, in another volume group, or in NFS-mounted file systems. If these fields are left blank, the mkcd command creates these file systems, and removes them when the command completes, unless you specify differently in later steps in this procedure.
  6. If you did not enter any information in the file systems' fields, you can select to have the mkcd command either create these file systems in the rootvg, or in another volume group. If the default of rootvg is chosen and a mksysb image is being created, the mkcd command adds the file systems to the exclude file and calls the mksysb command with the -e exclude files option.
  7. In the Do you want the CD or DVD to be bootable? field, select yes to have a boot image created on the CD or DVD. If you select no, you must boot from a product CD at the same version.release.maintenance level, and then select to install the system backup from the system backup CD.
  8. If you change the Remove final images after creating CD? field to no, the file system for the CD images (that you specified earlier in this procedure) remains after the CD has been recorded.
  9. If you change the Create the CD now? field to no, the file system for the CD images (that you specified earlier in this procedure) remains. The settings that you selected in this procedure remain valid, but the CD is not created at this time.
  10. If you intend to use an Install bundle file, type the full path name to the bundle file. The mkcd command copies the file into the CD file system. You must have the bundle file already specified in the BUNDLES field, either in the bosinst.data file of the mksysb image or in a user-specified bosinst.data file. When this option is used to have the bundle file placed on the CD, the location in the BUNDLES field of the bosinst.data file must be as follows: 
    /../usr/sys/inst.data/user_bundles/bundle_file_name
  11. To place additional packages on the CD or DVD, enter the name of the file that contains the packages list in the File with list of packages to copy to CD field. The format of this file is one package name per line.

    If you are planning to install one or more bundles after the mksysb image is restored, follow the directions in the previous step to specify the bundle file. You can then use this option to have packages listed in the bundle available on the CD. If this option is used, you must also specify the location of installation images in the next step.

  12. Enter the location of installation images that are to be copied to the CD file system (if any) in the Location of packages to copy to CD field. This field is required if additional packages are to be placed on the CD (see the previous step). The location can be a directory or CD device.
  13. You can specify the full path name to a customization script in the Customization script field. If given, the mkcd command copies the script to the CD file system. You must have the CUSTOMIZATION_FILE field already set in the bosinst.data file in the mksysb image or else use a user-specified bosinst.data file with the CUSTOMIZATION_FILE field set. The mkcd command copies this file to the RAM file system. Therefore, the path in the CUSTOMIZATION_FILE field must be as follows: 
    /../filename
  14. You can use your own bosinst.data file, rather than the one in the mksysb image, by typing the full path name of your bosinst.data file in the User supplied bosinst.data file field.
  15. To turn on debugging for the mkcd command, set Debug output? to yes. The debug output goes to the smit.log.
  16. You can use your own image.data file, rather than the image.data file in the mksysb image, by typing the full path name of your image.data file for the User supplied image.data file field.
