The following list describes abbreviations used in the exerciser reports. To toggle
between two states for (example, Activate/Halt Devices), use the number of the device.
Acronym
Description

HOE Halt on error (use number to select)
RN Device is running
ST Device is stopped
Memory Exerciser
The memory exercisers are labeled memx , where x is a number for the exerciser.
Multiple exercisers can be active.
The memory exerciser requests as many memory buffers as possible from AIX. The
exerciser then fills the memory buffers with specified bit patterns, then reads and
compares the memory buffers to the specified bit patterns.
On systems with multiple processors, a process is started for each processor. The free
memory space is split evenly between the available processors, thus reducing the time
required to exercise all of the memory.
If the system is working properly, no comparison errors are produced. If a
nonrecoverable memory error occurs, the system crashes. Recoverable memory errors
are logged by the AIX operating system.
