Chapter 13. Maintenance and troubleshooting 607
Symptoms of a problem can include hosts being unable to access data, the system sent an
e-mail notification, an LED indicates an issue, or the CMM or FSM event logs indicate a
problem. In all these cases, the management GUI recommended action is the correct starting
point.
For a problem that you may experience, that is not resolved by using the management GUI, in
those situations, review the symptoms and follow the actions that are provided here. You
might be directed to the IBM Flex System V7000 Service Assistant GUI or to Flex System
chassis management devices.
It is highly recommended that you set up CLI access to the control enclosure after initial
configuration is complete. It allows you to run necessary CLI commands when you cannot
start the management GUI or the node canisters in the control enclosure are unable to run
the system software.
Attention: After you have created your clustered system, remove hardware components
only when directed to do so by the Fix Procedures. Failure to follow the procedures can
result in loss of access to data or loss of data. Follow the Fix Procedures when servicing a
control enclosure.
