Fixed in Oracle Hardware Management Pack 2.3.3.
In rare instances on Oracle x86 systems running Linux, the system might hang during the BIOS boot process after being reset. A BIOS error might also be displayed during boot, such as "AF OO". This issue can sometimes occur when the Oracle Hardware Management Pack management agent (hwmgmtd) is running and the Ethernet interface has been configured for network bonding.
This issue has been seen with the Oracle Server X5-4 in an Exalytic product configuration.
Workaround
If you encounter this issue, disable the management agent (hwmgmtd) and reboot the system.
From the Linux host when logged in as administrator, enter the following commands to stop and disable the management agent:
# /sbin/chkconfig hwmgmtd off # /sbin/service hwmgmtd stop
Use ipmitool to reset the service processor by entering the command:
# ipmitool bmc reset cold
Reboot the system by entering the command:
# reboot
The system should reboot normally.
