System logs show failure entry for a storage controller even
though it is working correctly
The PowerEdge RAID Controller (PERC) family of enterprise-class controllers is designed for enhanced performance, increased
reliability, fault tolerance, and simplified management. These controllers provide a powerful, easy-to-manage way to create a
robust infrastructure and help maximize server uptime. The battery installed on these controllers help in ensuring data integrity
in case of power outages.
About this task
When the controller battery is discharged, the system recharges the battery and reconditions it. During this reconditioning, you
may see a failure in the system logs. To confirm that the battery is working correctly, check the hardware details on any of the
Dell EMC systems management solutions. This error can also be resolved by clearing the static build-up in the system. To clear
the static build-up, perform the following steps:
Steps
1. Shut down the system.
2. Disconnect all the power cables.
3. Press and hold power button for 15 seconds.
4. Reconnect all the cables and turn the system on.
Results
Check the hardware details to ensure that the controller is working correctly.
Troubleshooting hard drives
Prerequisites
CAUTION:
This troubleshooting procedure can erase data stored on the hard drive. Before you proceed, back up
all files on the hard drive.
CAUTION: Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or

NOTE: Ensure that the sleds internal SATA cables are connected correctly.
Steps
1. Run the appropriate diagnostic test. See the Using system diagnostics section.
Depending on the results of the diagnostics test, proceed as required through the following steps.
2. If your system has a RAID controller and your hard drives are configured in a RAID array, perform the following steps:
a. Restart the system and press F10 during system startup to run the Dell Lifecycle Controller, and then run the Hardware
Configuration wizard to check the RAID configuration.
See the Dell Lifecycle Controller documentation or online help for information about RAID configuration.
b. Ensure that the hard drives are configured correctly for the RAID array.
c. Take the hard drive offline and reseat the drive.
d. Exit the configuration utility and allow the system to boot to the operating system.
3. Ensure that the needed device drivers for your controller card are installed and are configured correctly. For more
information, see the operating system documentation.
4. Restart the system and enter the System Setup.
5. Verify that the controller is enabled and the drives are displayed in the System Setup.
