SMART Thermal Shutdown

Does my enclosure support this feature? See Supported Features.

Enclosure management provides a feature which automatically shuts down the operating system and turns off the

server and enclosure, when the temperature of the enclosure drops below the minimum threshold value or exceeds the

maximum threshold value. The temperature, when shutdown occurs, is determined by the Minimum Failure Threshold

and the Maximum Failure Threshold value. These thresholds are default settings that cannot be changed.

NOTE: Thermal shutdown does not apply to the LSI PCI-e U320 controllers, and any SAS or SATA internal or

external storage.

Thermal Shutdown for the 20xS and 21xS Enclosures

For the 20

S and 21

S enclosures, the operating system shuts down and the server turns off when the enclosure

reaches 0 degrees celsius or 50 degrees celsius. The enclosure turns off after the server is turned off.

Thermal Shutdown for the

220S

and

221S

Enclosures

For the 220S and 221S, the operating system shuts down and the server turns off at 0 degrees celsius or 50 degrees

celsius if you have not implemented Channel Redundancy and Thermal Shutdown. The enclosure turns off only when

you have implemented channel redundancy enabled smart thermal shutdown using the command-line interface (CLI)

and is set at 0 degrees celsius or 50 degree celsius. This does not result in data loss because the redundant data resides

on the enclosure attached to the other channel.

The

220S

and

221S

enclosures automatically turn off when their temperature reaches 55 degrees celsius. This shutdown

occurs even if channel redundancy is implemented or if Storage Management is installed.

You can enable smart thermal shutdown using the command-line interface. For more information, see the
