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.

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.
