Theexerciser then fills the memory buffers with specified bit patterns, then reads andcompares the memory buffers to the specified bit patterns.On systems with multiple processors, a process is started for each processor. The freememory space is split evenly between the available processors, thus reducing the timerequired to exercise all of the memory.If the system is working properly, no comparison errors are produced. If anonrecoverable memory error occurs, the system crashes. Recoverable memory errorsare logged by the AIX operating system.The following items must be available to run this service aid:v Online diagnostics loaded in maintenance modev 128 KB of free space in /etc/lpp/diagnostics/datav The following commands must be available:– vmstat– lsps– bootinfoChapter 6.
