Abbreviations

The following list describes abbreviations used in the exerciser reports.
Acronym Description
COE Continue on error (use number to select).
CP Device has run the specified number of cycles and is not running.
DD The exerciser has been terminated by a signal.
ER Device has stopped with an error.
HG The device is hung.
HOE Halt on error (use number to select).
RN Device is running.
ST Device is stopped.

Memory Exerciser

The memory exerciser is labeled mem0. The exerciser requests as many memory buffers as possible from
AIX. The exerciser fills these buffers with specified bit patterns and then compares them to the original bit
patterns. If memory is removed as a result of processors being reconfigured dynamically, the exerciser
terminates.
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.
Running this service aid requires 128 KB of free space in /etc/lpp/diagnostics/data.

Tape Exerciser

The tape exerciser is labeled rmtx, where x is the number of a specific device. The exerciser performs
read, write, and compare operations using known data patterns. A tape device and Test Diagnostic
Cartridge are required to run this exerciser. The actual Test Diagnostics Cartridge depends upon the
specific tape device being tested. The exerciser automatically rewinds the tape. Test Requirements are:
v Tape device
v Test Diagnostic Cartridge (the part number depends upon tape device)

Diskette Exerciser

The diskette exerciser is labeled fdx, where x is the number of a specific device. The exerciser performs
read, write, and compare operations using known data patterns. A scratch diskette is required to run this
exerciser, data on the scratch diskette is destroyed. Test requirements are:
v Diskette device
v Scratch diskette (data on diskette is destroyed)

CD-ROM Exerciser

The CD-ROM exerciser is labeled cdx, where x is the number of a specific device. The exerciser performs
read and compare operations using known data patterns. A CD-ROM device and a Test Disc is required to
run this exerciser. Test requirements are:
