The following procedure describes how to identify a corrupted boot image and re-create it. If your machine is currently running and you know the boot image has been corrupted or deleted, re-create the boot image by running the bosboot command with root authority.
Attention: Never
reboot the system when you suspect the boot image is corrupted.
The following procedure assumes your system is not rebooting
correctly because of a corrupted boot image. If possible, protect your system
from a possible loss of data or functionality by scheduling your downtime when
it least impacts your workload.
2. Power on the machine following the instructions provided with your
system.
3. From the System Management Services menu, select Multiboot.
4. From the next screen, select Install From.
5. Select the device that holds the product media and then select Install.
6. Select the AIX version icon.
7. Follow the online instructions until you can select which mode you
use for installation. At that point, select Start Maintenance
Mode for System Recovery.
8. Select Access a Root Volume Group.
9. Follow the online instructions until you can select Access this Volume Group and start a shell.
10. Use the bosboot command to
re-create the boot image. For example:
bosboot -a -d /dev/hdisk0
If the command fails and you receive the following message:
0301-165 bosboot: WARNING! bosboot failed - do not attempt to boot device.
Try to resolve the problem using one of the following options, and
then run the bosboot command again until you have
successfully created a boot image:
·
Delete the default boot logical
volume (hd5) and then create a new hd5.
Or
·
Run diagnostics on the hard
disk. Repair or replace, as necessary.
If the bosboot command continues to fail,
contact your customer support representative.
Attention: If the bosboot command fails while
creating a boot image, do not reboot your machine.
11. When the bosboot command is successful,
use the reboot command to reboot
your system.
