Controlled thermal shutdown
Symptom
If the thermal temperature of the controller nodes or drives increases to the point that temperature
exceeds the acceptable range, alert notifications are displayed in the HPE 3PAR StoreServ Management
Console (SSMC), and then a controlled shutdown of the component occurs automatically as a protective
action.
Cause
Internal sensors monitor the temperature of the controller nodes and drives. If the temperature of these
components exceeds the specified component temperature threshold, a controlled shutdown occurs. The
storage system attempts to remain online and not shutdown any additional controller nodes, unless
multiple drives have been spun down due to exceeding the acceptable temperature range. If the system
shuts down due to a pending TOC quorum loss from the spin down of too many drives, power remains on
for the controller nodes, drives, and drive enclosures.
For overheated controller nodes, a single controller node is shut down if one of its sensors reports a
critical temperature.
For overheated drives, the drives are spun down individually. With multiple overheated drives being spun
down, there is the danger of a TOC quorum loss, so the system executes a controlled shutdown. For a
controlled shutdown, the hardware remains powered on and the controller nodes reboot when the
ambient temperature has reduced and remains in the acceptable range for at least 30 minutes.
Log files collection
For a service event, it might be necessary to collect the HPE 3PAR Service Processor (SP) log files for
Hewlett Packard Enterprise support.
Collecting HPE 3PAR SmartStart log files—OS 3.2.2 and SP 4.x
The HPE 3PAR SmartStart log files are located in this folder:
C:\Users\<username>\SmartStart
\log
. Add these log files to a zip file for Hewlett Packard Enterprise support
NOTE:
You can continue to access the HPE 3PAR SmartStart log files in the
Users
folder even after you
have removed HPE 3PAR SmartStart from your storage system.
Collecting service processor log files—SP 5.x
The following tools collect data from the service processor (SP):
•
Audit and Logging Information
—Provides audit and logging information of an attached storage
system and service processor usage. This file is gathered as part of an SPLOR and Hewlett Packard
Enterprise Support personnel can view the file using HPE Service Tools and Technical Support
(STaTS).
The service processor audit Information is contained in the
audit.log
file, which provides the
following audit information:
