1.Open the Subsystem Management window.
2.Select the component button for each storage expansion enclosure in this storage subsystem, and view the status of each of the components.
The status for each component is either Optimal or Needs Attention.
3.Does any component have a Needs Attention status?
vYes - Go to step 4.
vNo - All components are Optimal. Go to step 6.
4.Select the Recovery Guru toolbar button. Perform the procedure in the Recovery Guru to correct the problem. The Recovery Guru might direct you to replace the failed component. If so, go to step 5.
Attention: If the fault requires you to power off an attached storage expansion enclosure, you might need to cycle the power on the DS4000 storage subsystem and all remaining storage expansion enclosures in the storage subsystem. Contact IBM Customer and Technical Support before powering off any attached storage expansion enclosures.
5.If applicable, mute the alarm.
6.Check the indicator LEDs on the front and the back of the storage expansion enclosure.
A green LED denotes a normal status; an amber LED denotes a hardware fault.
7.Is an amber LED on?
vYes - Locate and troubleshoot the failed components. See “Checking the LEDs.”
vNo - You are finished with this procedure. If you are still experiencing a problem with this storage subsystem, create, save, and print a storage subsystem profile. This information might be helpful when troubleshooting. Contact IBM Customer and Technical Support for assistance. When the recovery procedure is completed, select Recheck in the Recovery Guru to rerun the Recovery Guru and to ensure that the problem has been corrected.
Checking the LEDs
The LEDs display the status of the storage subsystem and components. The color of the LED is important.
vGreen LEDs indicate a normal operating status
vAmber LEDs (Needs Attention) indicate a possible failure
vBlue LED on a CRU indicates that is safe to remove the component
The DS4700 Express Storage Subsystem also has a blue Global Locate LED that is lit when the menu function is selected in the Subsystem Management window, causing the LOCATE command to be sent to the DS4700 Express.
It is important to check all the LEDs on the front and back of the storage subsystem when you turn on the power. During power up, the indicator LEDs blink intermittently as the storage subsystem and components complete the
