5001 Controller warning - power supply voltage out of range
Explanation: Power supply voltage is not yet critical, but is out of the normal operating range. Potential causes are
power supply failure and controller sensor failure.
System action: By default, the SAS RAID Module system information indicator is not turned on and the operator is
notified of this alert by e-mail. The alert clears automatically when the voltage returns to the normal operating range.
Operator response:
1. Perform a concurrent power supply replacement.
2. If the problem persists, the controller sensor might be failing. Replace the controller. See "Replacing a single
controller using the CLI" on page 154 or "Replacing a single controller using the SCM" on page 155.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
5002 Controller warning - power supply current out of range
Explanation: Power supply current is not yet critical, but is out of the normal operating range. Potential causes are
power supply failure and controller sensor failure.
System action: By default, the SAS RAID Module system information indicator is not turned on and the operator is
notified of this alert by e-mail. The alert clears automatically when the current returns to the normal operating range.
Operator response:
1. Perform a concurrent power supply replacement.
2. If the problem persists, the controller sensor might be failing. Replace the controller. See "Replacing a single
controller using the CLI" on page 154 or "Replacing a single controller using the SCM" on page 155.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
9000 Controller critical - temperature out of range
Explanation: The temperature detected in the controller is outside the normal operating range. The controller is
initiating an orderly shutdown.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is
notified of this alert by e-mail. If both controllers or the survivor controller has generated this alert, the system is
automatically taken offline to preserve data integrity. If only one controller in a redundant system is generating this
error, that controller shuts down and the remaining controller assumes control of all volumes. The alert clears
automatically when the controller temperature returns to the normal operating range.
Operator response:
1. Make sure the room environment is within specification for the Blade Center.
2. Check the fans used to cool the controller to see if they are operating correctly.
3. If no cooling problem exists, the temperature sensor in the controller might be malfunctioning. Replace the
controller.
