Recovering ThinkSystem, Converged, NeXtScale, or System x M5 or M6 server management after a management server failure by using cimcli
You can recover management of a ThinkSystem, Converged, NeXtScale, or System x M5 or M6 server by using the cimcli utility to clear the CIM subscriptions.
Before you begin
OpenPegasus with the cimcli utility must be installed on a system that has network access to the target server. For information about downloading, configuring, and compiling OpenPegasus, see the OpenPegasus Release RPMs for Linux website.
Note
For Red Hat Enterprise Linux (RHEL) Server 7 and later, OpenPegasus source and binary RPMs are included as part of the Red Hat distribution. The top-pegasus-test.x86_64 package includes the cimcli utility.
About this task
After the server is recovered, you can manage the server again. All information about the server (such as network settings, server policies, and firmware compliance policies) is retained.
Procedure
Complete the following steps from a server that uses Lenovo XClarity Administrator managed authentication and on which OpenPegasus is installed to recover server management.
If Encapsulation is enabled on the device:
Connect to the target server from a system that is configured to use the IP address of the failed XClarity Administrator virtual appliance.
Disable Encapsulation by opening an SSH session to the device and running the following command:
encaps lite off
Run the following commands to determine the CIM instances for CIM_ListenerDestinationCIMXML, CIM_Indicationfilter and CIM_IndicationSubscription.
Run following command to delete each the CIM instance for CIM_ListenerDestinationCIMXML, CIM_Indicationfilter and CIM_IndicationSubscription, one at a time.
where, <IP_address>, <user_ID> and <password> are the IP address, user ID and password for the management controller, and <cim_instance> is the information returned for each CIM instance in the previous step, surrounded by single quotes. For example:
After Lenovo XClarity Administrator is restored or replaced, you can manage the System x or NeXtScale server again (see Managing servers). All information about the server (such as network settings, server policies, and firmware compliance policies) is retained.
