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.
Running this service aid requires 128 KB of free space in the /etc/lpp/diagnostics/data file.
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:
vTape device
vTest Diagnostic Cartridge (The part number depends upon the 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:
vDiskette device
vScratch diskette (data on diskette is destroyed)
CD-ROM Exerciser
The
v
vTest Disc part number 81F8902
