User can increase the System Input Power Cap to a higher value that allow for additional power allocation to the fans without an impact on server performance. Troubleshooting Alerts Use the CMC log and the trace log to troubleshoot CMC alerts. The success or failure of each email and/or SNMP trap delivery attempt is logged into the CMC log. Additional information describing the particular error is logged in the trace log. However, since SNMP does not confirm delivery of traps, use a network analyzer or a tool such as Microsoft's snmputil to trace the packets on the managed system. Viewing Event Logs You can view hardware- and chassis logs for information on system-critical events that occur on the managed system. Viewing Hardware Log CMC generates a hardware log of events that occur on the chassis. You can view the hardware log using the web interface and remote RACADM. NOTE: To clear the hardware log, you must have Clear Logs Administrator privilege. NOTE: You can configure CMC to send email or SNMP traps when specific events occur. For information on configuring CMC to send alerts, see Configuring CMC To Send Alerts.

To view the hardware logs using CMC Web interface, in the left pane, click Chassis Overview → Logs. The Hardware Log page is displayed. To save a copy of the hardware log to your managed station or network, click Save Log, and then specify a location for a text file of the log. NOTE: Since the log is saved as a text file, the graphical images used to indicate severity in the user interface do not appear. In the text file, severity is indicated with the words OK, Informational, Unknown, Warning, and Severe. The date and time entries appear in ascending order. If appears in the Date/Time column, it means that the event occurred during the turn-on or turn-off of any of the modules, when a date or time is not available.

Problem:
Overall server performance decreases when the ambient temperature increases in the data center.
–
Resolution:
This can occur if the
System Input Power Cap
has been configured to a value that results in
an increased power need by fans having to be made up by reduction in the power allocation to the
servers. User can increase the
System Input Power Cap
to a higher value that allow for additional power
allocation to the fans without an impact on server performance.
Troubleshooting Alerts
Use the CMC log and the trace log to troubleshoot CMC alerts. The success or failure of each email and/or SNMP trap
delivery attempt is logged into the CMC log. Additional information describing the particular error is logged in the trace
log. However, since SNMP does not confirm delivery of traps, use a network analyzer or a tool such as Microsoft’s
snmputil to trace the packets on the managed system.
Viewing Event Logs
You can view hardware- and chassis logs for information on system-critical events that occur on the managed system.
Viewing Hardware Log
CMC generates a hardware log of events that occur on the chassis. You can view the hardware log using the web
interface and remote RACADM.
NOTE:
To clear the hardware log, you must have
Clear Logs Administrator
privilege.
NOTE:
You can configure CMC to send email or SNMP traps when specific events occur. For information on
configuring CMC to send alerts, see
Configuring CMC To Send Alerts

Viewing Hardware Logs Using CMC Web Interface
You can view, save, and clear the hardware log. You can sort the log entries based on Severity, Date/Time, or
Description by clicking the column heading. Subsequent clicks on the column headings reverse the sort.
To view the hardware logs using CMC Web interface, in the left pane, click
Chassis Overview
→
Logs
. The
Hardware
Log
page is displayed. To save a copy of the hardware log to your managed station or network, click
Save Log
, and then
specify a location for a text file of the log.
NOTE:
Since the log is saved as a text file, the graphical images used to indicate severity in the user interface do
not appear. In the text file, severity is indicated with the words
OK
,
Informational
,
Unknown
,
Warning
, and
Severe
.
The date and time entries appear in ascending order. If <SYSTEM BOOT> appears in the
Date/Time
column, it
means that the event occurred during the turn-on or turn—off of any of the modules, when a date or time is not
available.
To clear the hardware log, click
Clear Log.
