Testing the ServeRAID 4x adapter
You can run all diagnostic operations for the ServeRAID adapters through the IBM
ServeRAID Configuration software in the Advanced Functions option. You can run
subsystem diagnostics through the system diagnostics.
Note: Before running any test, back up the current disk array configuration using
the ServeRAID diagnostics test program. Always keep a current backup of
the ServeRAID configuration information. Dynamic changes may occur in the
configuration due to hot-spare replacement.
