You can recover management of a ThinkSystem, Converged,
NeXtScale, or System x M5 or M6 server by resetting the baseboard
management-controller in the server to factory defaults.
Procedure
Complete the following steps to recover management of a server that
uses Lenovo XClarity Administrator managed authentication.
- If Encapsulation is enabled on the device, connect to the target management
controller from a system that is configured to use the IP address
of the failed XClarity Administrator virtual appliance.
- Reset the management controller to the factory
defaults.
- Log in to the management controller web interface for
the server using the recovery user account and password that you created
before the server was managed by XClarity Administrator.
- Click the IMM Management tab.
- Click IMM Reset to factory defaults.
- Click OK to confirm the reset
action.
Important: After the BMC configuration is complete,
the BMC is restarted. If this is a local server, your TCP/IP connection
is broken and you must reconfigure the network interface to restore
connectivity.
- Log on to the management controller web interface
for the server again.
Notes:
- The BMC is initially configured to attempt to obtain an IP address
from a DHCP server. If it cannot, it uses the static IPv4 address 192.168.70.125.
- The IMMBMC is set initially with a user name of USERID and password of PASSW0RD (with a zero). This
default user account has Supervisor access. Change this user name
and password during your initial configuration for enhanced security.
- Reconfigure the network interface to restore
connectivity. For more information, see the Integrated Management Module II online documentation.
What to do next
After XClarity Administrator is restored or replaced, you can manage the server again
(see Managing servers). All information about
the server (such as network settings, server policies, and firmware
compliance policies) is retained.
If the server was configured
using Configuration Patterns, you can deactivate and then re-activate the server profile
that was assigned to the server to apply the configuration (see Working with server profiles).
