5.6.2 HDD
 DiskCntlrTest (PP): Verifies the random data written to disks remains unchanged. It verifies
only IDE and SCSI controllers that are associated with mounted file systems. Disk
controllers associated with read-only mounted file systems are not verified.
5.6.3 Memory
 MemCntlrTest (SP & PP): Randomly writes to areas of memory, then reads the memory
back to ensure the values written remain unchanged.
 RandomMemoryTest (SP & PP): Performs stress-testing on the memory subsystem. This
test is effective in finding intermittent and non-deterministic faults. The problems in other
hardware areas such as overheating CPU, out-of-specification power supply, and so on can
cause memory faults.
 EdacErrorStatsTest (SP): Checks for the occurrence of one bit and two bit errors in the RAM.
5.6.4 OS
 MemSepTest (SP & PP): Ensures that user space programs cannot read and write to areas of
memory utilized by items such as Video RAM and kernel code.
 SupervisorInstrTest (SP): Ensures that the enforcement of the property that privileged
instructions should only be in supervisor mode is still in effect. The set of privileged
instructions tested to confirm this is architecture dependent.
5.6.5 PCI
 PCIScanTest (SP): Enumerates all active PCI devices in the blade and ensures board default
configuration is active. This test need to be executed under supervisory mode.
Executing this test in user mode may result in failure of test.
