Installation Guide and Reference

Creating and Installing System Backups

This chapter provides information on creating and installing system backups. The chapter includes the following sections:

Notes:
  1. References to CD in this chapter also apply to DVD.
  2. AIX 5.2 provides the cdromd CD and DVD automount facility, which is included in the bos.cdmount fileset. To determine if the cdromd daemon is enabled on your system, run the following command:
    # lssrc -s cdromd
    The cdromd daemon can interfere with scripts, applications, or instructions which attempt to mount the CD or DVD device without first checking to see if the device is already enabled. A resource or device busy error occurs in such a condition. Use the cdumount or cdeject command to unmount the device. Then mount the device as specified in the program or instructions. Alternatively, use the cdcheck -m or mount command to determine the current mount point of the device. For further information, see the cdromd command documentation in the AIX 5L Version 5.2 Commands Reference.

    The installation code allows for this automatic mounting. If cdromd is enabled and the mkcd command is run, the CD-R or DVD-RAM is ejected after the image is completed. If you do not want to have the media ejected, then the cdromd daemon should be put in the inoperative state with the following command:

    # stopsrc -s cdromd
