Issue 1: Troubleshooting a Hard Drive


If your system has a RAID controller and your hard drives are configured in a RAID array, perform the following steps:
  1. Restart the system and press <F10> during system startup to run the Lifecycle Controller, and then run the Hardware Configuration Wizard to check the RAID configuration.

  2. Ensure that the hard drive(s) have been configured correctly for the RAID array.

  3. Take the hard drive offline and reseat the drive.

  4. Exit the configuration utility and allow the system to boot to the operating system.

  5. Ensure that the required device drivers for your controller card are installed and are configured correctly.

  6. See the Operating System documentation for more information.

  7. Restart the system and enter the System Setup.

  8. Verify that the controller is enabled and the drives are displayed in the System Setup.

Issue 2: Rebuilding a Failed Physical Disk


Issue:
Rebuilding a physical disk after one of them is in a failed state.

Corrective Action:
If you have configured hot spares, the PERC card automatically tries to use one of them to rebuild a physical disk that is in a failed state. Manual rebuild is necessary if no hot spares with enough capacity to rebuild the failed physical disks are available. You must insert a physical disk with enough storage in the subsystem before rebuilding the physical disk.

NOTE: You can use the CONTROLLER BIOS Configuration Utility (<Ctrl> <R>) or Dell OpenManage storage management application to perform a manual rebuild of an individual physical disk.

Issue 3: Smart Errors


SMART monitors the internal performance of all motors, heads, and physical disk electronics and detects predictable physical disk failures.
NOTE: For information about where to find reports of SMART errors that could indicate hardware failure, see the Dell OpenManage storage management documentation at support.dell.com/manuals.
Issue 1: Error Detected On A Physical Disk In A Redundant Virtual Disk
Issue: A SMART error is detected on a physical disk in a redundant virtual disk.
Corrective Action:
  1. Back up your data.

  2. Force the physical disk offline.
    NOTE: If a hot spare is present, the rebuild starts with the hot spare after the disk is forced offline.

  3. Replace the disk with a new physical disk of equal or higher capacity.

  4. Perform the Replace Member operation.
    NOTE: The Replace Member operation allows you to copy data from a source physical disk of a virtual disk to a target physical disk that is not a part of the virtual disk. For more information about the Replace Member feature, see the topic Using Replace Member and Revertible Hot Spares.

Issue 2: Smart Error Detected On A Physical Disk In A Non-Redundant Virtual Disk
Issue: A SMART error is detected on a physical disk in a redundant virtual disk.
Corrective Action:
  1. Back up your data.

  2. Use Replace Member or set up a global hot spare to replace the disk automatically. NOTE: For more information about the Replace Member feature, see the topic Using Replace Member And Revertible Hot Spares.

  3. Replace the affected physical disk with a new physical disk of equal or higher capacity.

  4. Restore from the backup.

Issue 4: Foreign Configuration


When a foreign configuration is present, you can select Foreign Configuration View to display the configuration. The screen shows the foreign configuration as it would be if you import it. You can preview the foreign configuration before you decide whether to import it or clear it.
In some cases, a foreign configuration cannot be imported. If a physical disk in a virtual disk is rebuilding, the physical disk's state is set to Rebuild. No virtual disk target ID displays for virtual disks that cannot be imported.
The section Importing or Clearing Foreign Configurations Using the Foreign Configuration View Screen contains the procedures you can use to manage the foreign configurations.
NOTE: The CONTROLLER BIOS Configuration Utility (<Ctrl> <R>) reports error codes for failed imports of foreign configurations.
Foreign Configuration Found Error Message

Foreign configuration(s) found on adapter. Press any key to continue, or ’C’ to load the configuration utility or ’F’ to import foreign configuration(s) and continue.

Probable Cause:
When a controller firmware detects a physical disk with existing foreign metadata, it flags the physical disk as foreign and generates an alert indicating that a foreign disk was detected.

Corrective Action:
Press <F> at this prompt to import the configuration (if all member disks of the virtual disk are present) without loading the CONTROLLER BIOS Configuration Utility (<Ctrl> <R>). Or press <C> to enter the CONTROLLER BIOS Configuration Utility (<Ctrl> <R>) and either import or clear the foreign configuration.

Foreign Configuration Not Found In <Ctrl> <R> Error Message

The foreign configuration message is present during POST but no foreign configurations are present in the foreign view page in <Ctrl> <R>. All virtual disks are in an optimal state.

Corrective Action:
Ensure all your PDs are present and all VDs are in optimal state. Clear the foreign configuration using <Ctrl> <R> or Dell OpenManage Server Administrator Storage Management.

CAUTION: The physical disk goes to Ready state when you clear the foreign configuration.
If you insert a physical disk that was previously a member of a virtual disk in the system, and that disk’s previous location has been taken by a replacement disk through a rebuild, you must manually remove the foreign configuration flag of the newly inserted disk.

Issue 5: Battery Learn Cycle / Battery or Memory Errors


Battery Transparent Learn Cycle
NOTE: Batteries are only supported on PERC H710, H710P, and H810 cards.
A Transparent Learn Cycle (TLC) is a periodic operation that calculates the charge that is remaining in the battery to ensure there is sufficient energy. The operation runs automatically, and causes no impact to system or controller performance.
The controller automatically performs the TLC on the battery to calibrate and gauge its charge capacity once every 90 days. The operation can be performed manually, if required.
NOTE: Virtual disks stay in Write Back mode, if enabled, during transparent learn cycle. When the TLC completes, the controller sets the next TLC to +90 days.
Memory or Battery Problem Error Message

Memory/Battery problems were detected. The adapter has recovered, but cached data was lost. Press any key to continue.

Probable Cause:
The message occurs under the following conditions:

  • The adapter detects data in the controller cache that has not yet been written to the disk subsystem.
  • The controller detects an Error-Correcting Code (ECC) error while performing its cache checking routine during initialization.
  • The controller discards the cache rather than sending it to the disk subsystem because the data integrity cannot be guaranteed.
  • The battery may be under charged.

Corrective Action:
Allow the battery to charge fully to resolve this problem.
If the problem persists, contact Dell Technical Support.
