+Description:   Contains the PIM/PAM/POM values, as reported by the
+               channel subsystem when last queried by the common I/O
+               layer (this implies that this attribute is not neccessarily
+               in sync with the values current in the channel subsystem).
+               Note: This is an I/O-subchannel specific attribute.
