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 PowerVault 20xS and PowerVault 21xS Enclosures
For the PowerVault 20xS and PowerVault 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 PowerVault 220S and PowerVault 221S Enclosures
For the PowerVault 220S and PowerVault 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 PowerVault 220S and PowerVault 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.
