When we need to reset the CMM of a SUN BLADE 6000 MODULAR SYSTEM and we have no access via ssh or web, we can do it through some of the blades in the chassis using ipmitool.
For example we may find that we can not access because we have reached the maximum number of sessions:
# ssh root@CMM-net-mgt Password: shell: Maximum number of sessions exhausted Connection to CMM-net-mgt closed. #
As we have no access, we can not reset it. When this happens, we access to the operating system of any of the blades and run the following
root@blade1 # ipmitool -H CMM-net-mgt -U root bmc reset cold Password: Sent cold reset command to MC root@blade1 #
and after that we can logging without problems
# ssh root@CMM-net-mgt Password: Sun(TM) Integrated Lights Out Manager Version 184.108.40.206 r47352 Copyright 2009 Sun Microsystems, Inc. All rights reserved. Use is subject to license terms. Warning: password is set to factory default.
