138 Enclosures and Backplanes
SMART Thermal Shutdown
Does my enclosure support this feature? See
Supported Features
.
Enclosure management provides a feature which automatically shuts down
the operating system, the server, and the enclosure when the enclosure’s
temperature reaches dangerous extremes. The temperature, when shutdown
occurs, is determined by the enclosure temperature probe’s Minimum Failure
Threshold and the Maximum Failure Threshold. 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 20xS and 21xS enclosures, the operating system shuts down and the
server powers off when the enclosure reaches 0 degrees Celsius or 50 degrees
Celsius. After the server powers off, the enclosure also powers off.
Thermal Shutdown for the 220S and 221S Enclosures
For the 220S and 221S, the operating system and server turn off at 0 degrees
Celsius or 50 degrees Celsius if you have not implemented Channel
Redundancy and Thermal Shutdown. If you have implemented channel
redundancy enabled smart thermal shutdown using the command line
interface (CLI), then only the enclosure shuts down at 0 degrees Celsius or 50
degrees Celsius. This does not result in data loss because 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 whether or not you have
implemented channel redundancy or have Storage Management installed.
You can enable smart thermal shutdown using the command line interface.
For more information, see the Server Administrator Command Line Interface
User’s Guide.
Changing the Mode on 220S and 221S Enclosures
When toggling the bus configuration switch on a 220S or 221S enclosure, the
enclosure should be powered off. The bus configuration switch is used to
change the enclosure to split bus, joined bus, or clustered mode. If you
change the 220S or 221S enclosure mode with the enclosure powered on, the
