value of the HIGH OPERATING TEMPERATURE LIMIT TRIGGER field, then the device server shall report an informational exception condition with
the additional sense code set to WARNING - HIGH OPERATING TEMPERATURE LIMIT EXCEEDED.
HIGH OPERATING TEMPERATURE LIMIT RESET field
The HIGH OPERATING TEMPERATURE LIMIT RESET field indicates the temperature at which the informational exception condition for the asso-
ciated high critical temperature limit, if any, shall be cleared.
LOW OPERATING TEMPERATURE LIMIT RESET field
The LOW OPERATING TEMPERATURE LIMIT RESET field indicates the temperature at which the informational exception condition for the associ-
ated low critical temperature limit, if any, shall be cleared.
LOW OPERATING TEMPERATURE LIMIT TRIGGER field
The LOW OPERATING TEMPERATURE LIMIT TRIGGER field indicates the minimum temperature at this sensor for which the logical unit is capable
of operating continuously without degrading the logical unit's reliability beyond manufacturer accepted limits. If the EWASC bit is set to one in
the Information Exceptions Control mode page (see SBC-4, SSC-4, or SMC-3) and the associated current temperature
(see 5.2.8.2) is less than
the value of the LOW OPERATING TEMPERATURE LIMIT TRIGGER field, then the device server shall report an informational exception condition
with the additional sense code set to WARNING - LOW OPERATING TEMPERATURE LIMIT EXCEEDED.
