Functional Overview
The show environment command display reports the current environmental status of the system.
The report displays the date and time of the query, the refresh times, the overall system status, and
any parameters that are out of the normal values. No parameters are displayed if the system status is
normal. If the status is not normal, only the worst-case status level for each parameter is reported.
The example that follows shows the display for a system in which all monitored parameters are
within Normal range.
The show environment all command displays an extended report that includes all the information
in the show environment command display, plus the type and status of installed power supplies, the
number of intermittent powerfails (if any) since the system was last powered on, and the measured
values at the two temperature sensors and the four DC lines. In the example that follows, a power
supply is installed in the lower power-supply bay, but it is either not turned on or it has failed. The
refresh time indicates that the parameters will be measured again in 40 seconds; any changes to a
measurement will not be reflected in the display until at least 40 seconds have elapsed, and the
current information is refreshed.
The show environment last command retrieves and displays the NVRAM log of the reason for the
last shutdown and the environmental status at that time. If no status is available, it displays the reason
as unknown.
