Procedure to Rebuild the Device Configuration Database

WARNING: When you rebuild the ODM customized devices database, you will lose any special configuration you have for customized devices. For example:

Perform the following procedures to replace the current device database with a default minimum configuration database. This new database will be in effect on the next system reboot.

  1. Boot from NON_AUTOINSTALL media of the same version as the system and access the rootvg volume group without mounting the file systems.

  2. Run the following to mount the /dev/hd2(/usr) file system.
              mount /dev/hd2 /usr
  3. This step is optional. With the following commands, copy the current system configuration to a backup directory:
              mount /dev/hd4 /mnt 
              mkdir /mnt/etc/objrepos/backup 
              cp /mnt/etc/objrepos/Cu* /mnt/etc/objrepos/backup
              umount /mnt
  4. Determine what disk or disks the boot image is on.
              lslv -l hd5 
  5. Save the RAM file-system-based device configuration database to the boot disk or disks. For example:
              savebase -d /dev/hdisk0
  6. Turn the key to the Normal position, if applicable, and run the following command.
The system should now reboot with a default device database. You will need to redefine the system console upon the initial boot. Afterwards, any customized devices will need to be redefined and any non-rootvg volume groups will need to be re-imported.
