6.2.4 Monitoring Physical Volumes
Physical volume failures can and do occur for many reasons. More often than
not they are caused by inadequate operating conditions, such as cables
connected to physical volumes left loosely on the floor risking being pulled out,
temperature and humidity not controlled properly, physical volumes exposed to
direct sunlight and strong magnetic fields. These physical conditions need to be
addressed for physical volumes to function properly. The tolerances of physical
volume may differ, and these can be obtained from the hardware specifications
supplied by the manufacturers.
Failures arising as a result of these conditions ...
