problem. In all these cases the management GUI recommended action is the correct starting 
point.

For problem that you might 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 may 
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, this 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.

You can remove and replace customer replaceable units (CRUs) from the control enclosure or 
the expansion enclosure.

Even though many of these procedures are hot-swappable, they are intended to be used only 
when your system is not up and running and performing I/O operations. If your system is 
powered on and performing I/O operations, go to the management GUI and follow the fix 
procedures. Performing the replacement actions without the assistance of the fix procedures 
can result in loss of data or loss of access to data.

Each replaceable unit has its own removal procedure. Sometimes you can find that a step 
within a procedure might refer you to a different remove and replace procedure. Complete the 
new procedure before you continue with the first procedure that you started.

Events that are detected are saved in an event log. As soon as an entry is made in this event 
log, the condition is analyzed. If any service activity is required, a notification is sent.

The following methods are used to notify you and the IBM Support Center of a new event:

1. If you enabled Simple Network Management Protocol (SNMP), an SNMP trap is sent to an 

SNMP manager that is configured by the customer.

2. If enabled, log messages can be forwarded from a sender to a receiver on an IP network 

by using the Syslog protocol.

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.

Attention: If your system is powered on and performing I/O operations, go to the 
management GUI and follow the fix procedures. Removing a node without the assistance 
of the fix procedures can result in loss of data or access to data

Note: Remove or replace CRU parts only when you are directed to do so. The field 
replaceable units (FRUs) must be installed only by trained service technicians.
