NL-SAS drives are not compatible with AutoMAID Level 4. Arrays with NL-SAS drives set to use
AutoMAID Level 4 will remain at AutoMAID Level 3.
If any drives are set to use AutoMAID Level 3 or 4, host timeout values (set for the host HBA either
through the HBA BIOS or a management application) should be set to a default of between 120 and
150 seconds to avoid the host requests timing out before the disk drives can power on and spin up to
full speed.
