If the BIOS data is valid and the iLO XML call is still reporting errors, a hardware problem
might be the cause. In that case, telephone HP Customer Service.
•
If the association problem is still not resolved after completing the suggested corrective actions
described here, something more unusual is wrong.
Check firewall ports on the CMS and the managed system and make sure SNMP is not being
blocked. Look for anything that might be blocking the proper flow of the association data.
25.20.3.2 Restoring the association of a bare-metal-discovered server blade
A server blade that was discovered (bare-metal discovery) but had no valid OS installed on it may
lose the association with its management processor.
To reduce the chance of this occurring, HP recommends that you use the Power Off Server tool to
power down discovered bare-metal servers. For information, see
You can restore the association of server blade by selecting the management processor and
reidentifying it with the Options
→Identify Systems... menu item.
25.20.3.3 Repairing the association of an unbooted managed system without an OS
If the managed system is not booted and does not have a valid OS installed on it, but the association
has gone away, there is no way to repair the association because there are no agents to ask for
the appropriate data. If that is the case, follow these steps to remove the managed system HP SIM
and use the Insight Control for Linux RAM disk to rediscover it:
1.
Delete the server and management processor from HP SIM.
2.
Get the server’s MAC address from the system BIOS, the iLO, or the Onboard Administrator
(where appropriate).
3.
Log in to the CMS as root.
4.
Navigate to the /opt/repository/boot/pxelinux.cfg directory.
5.
Delete any PXE configuration files that correspond to the MAC addresses you recorded in step
2. Here is an example of the contents of the /opt/repository/boot/pxelinux.cfg
directory.
# pwd
/opt/repository/boot/pxelinux.cfg

PXE boot the server as described in
7.
Monitor the HP Insight Control user interface; and the server's remote console and verify that
the server was successfully rediscovered and associated with its management processor.
8.
If the server does not have a valid OS installed on it, power off the server when it has completed
its discovery.
