Z Series Workstation - Detecting and Fixing a Hard Drive Failure in the RAID Controller Utility

1. Turn on the computer.
   The computer automatically enters POST.
2. During the Power-On Self-Test (POST), press Ctrl + I when prompted.
3. At POST, press any key for Option ROM Messages.
4. When available, press Ctrl + I to enter the Configuration Utility.

   note:

   The Port IDs for the hard drive(s) within the Configuration Utility do not represent the system board port IDs or internal hard drive bay IDs.

   Figure : Press CTRL + I

   
5. Select Create RAID Volume.
6. Find the hard disk drive (HDD) that is labeled either Degraded or Unconfigured Bad, and then take note of the HDD’s serial number.

7. Press esc to exit the utility, and then turn off the computer.

1. Disconnect the power cord from the computer.
2. Remove the cover from system.

   note:

   For exact remove and replace steps for your computer model, see the HP Service Media Library.

3. Find the HDD with the serial number identified in the previous step, and then remove that HDD.
4. Insert the new HDD, and then make sure that both the data and power connectors are seated properly.
5. Reconnect the power cord to the computer, and then restart the computer.

• RAID 1 (Mirrored) configuration
  If one hard disk stops working, replace the hard disk drive, and then use the Rebuild function in the NVIDIA Control Panel to rebuild RAID.
  If the data on both hard disk drives are identical and can be copied (synchronized) to the new hard disk drive.
• RAID 0 (striped) configurations
  It is not possible to rebuild RAID 0 (striped) configurations. In a striped RAID configuration, data is split between the two hard disk drives. If one hard disk drive stops working, you cannot retrieve the data. It is critical to create recovery discs and have a strategy for backing up data in case issues arise.

note:

Advanced Host Controller Interface (AHCI) is an interface specification that allows the storage driver to enable advanced Serial ATA features such as Native Command Queuing, native hot plug, and power management.

1. Turn on the computer.
2. During the Power-On Self-Test (POST), select the adapter for the controller, press Ctrl + C when prompted to enter the LSI Logic Configuration option ROM user interface.
   For more information, see the HP advisory: Manual Windows 7 Operating System Installation May Fail.

1. If a hard drive failure occurs, an on-screen message indicates the change to the RAID array before the utility opens.

   note:

   At any point during RAID configuration or management, you can click Home to return the main screen of the configuration utility, or click Exit to exit the application and cancel any unsaved changes.

2. When prompted, press C or CTRL+ H to enter the utility.
   After the POST completes, the WebBIOS runs.
3. From the Adapter Selection screen, select your adapter, and then click Start to enter the utility.
   Figure : Click Start

   
4. When the home screen displays, find the hard disk drive (HDD) that is colored red, and then take note of the HDD’s serial numbers.

1. On the next screen, select Unconfigured Good next to the relevant disk.
2. The disk is made part of a disk group.
3. Click Go.
   The next screen displays the configured disk groups. The group from which the original disk was missing is indicated.
4. Under DG Missing Row, select the location of the disk. The listed options are the locations where a disk was missing from the RAID array.
   The Replace Missing PD radio button is checked.
