HP Secure Encryption HP Secure Encryption is a controller-based, enterprise-class data encryption solution that protects data at rest on any bulk storage HDDs and SSDs attached to an HP Smart Array P431 Controller. The solution is compatible with HP key manager products and can operate with or without the presence of a key manager in the environment, depending on individual customer settings.
Feature Description 5 minutes or less Time required to recharge battery or capacitor pack Duration of battery 80 seconds or capacitor pack The battery or capacitor pack provides a sufficient duration to transfer the cached data from DDR memory to backup flash memory, where the data remains indefinitely or until a controller retrieves the data.
Installation and configuration Procedures for controllers in a server To install a stand-up controller in a server, choose one of the following procedures: • Installing a stand-up controller in an unconfigured server (on page 13) • Installing a stand-up controller in a previously configured server (on page 13) Installing a stand-up controller in an unconfigured server IMPORTANT: Do not power up the server until the hardware configuration is satisfactory, as described in the procedure given in this sect
3. Verify the server firmware is the latest revision. If necessary, update the server firmware ("Updating firmware" on page 19). 4. Do one of the following: 5. o If the new controller is the new boot device, install the device drivers ("Installing device drivers" on page 19). o If the new controller is not the new boot device, go to the next step. Power down the server.
WARNING: To reduce the risk of personal injury or damage to the equipment, consult the safety information and user documentation provided with the server before attempting the installation. Some servers contain high energy circuits, high current circuits, moving parts (such as fan blades), or any combination of these hazards, that may be exposed if covers and access panels are removed while the product is connected to a power source.
Configuration tools HP Smart Storage Administrator HP SSA is the main tool for configuring arrays on HP Smart Array controllers. It exists in three interface formats: the HP SSA GUI, the HP SSA CLI, and HP SSA Scripting. All formats provide support for configuration tasks. Some of the advanced tasks are available in only one format. The diagnostic features in HP SSA are also available in the standalone software HP Smart Storage Administrator Diagnostics Utility CLI.
UEFI System Utilities At this time, the HP ProLiant DL580 Gen8 Server is the only HP ProLiant Gen8 server that supports UEFI. For servers that support UEFI, the HP UEFI System Utilities is embedded in the system ROM.
Setting the controller order For servers running in legacy (non-UEFI) mode, use the following procedure to set the controller order using RBSU. 1. Power up the server. The server runs the POST sequence and briefly displays an RBSU prompt. 2. At the prompt, press the F9 key. After POST completes, RBSU starts. 3. Follow the on-screen instructions to set the boot order for the different controllers in the system. 4. Save the settings. 5. Exit from the utility.
System maintenance tools Updating firmware Server and controller firmware should be updated before using the controller for the first time, unless any installed software or components require an older version. For system software and firmware updates, download the SPP from the HP website (http://www.hp.com/go/spp). Installing device drivers IMPORTANT: Always perform a backup before installing or updating device drivers.
• HP Insight Diagnostics HP Insight Diagnostics is a tool that displays information about the system hardware configuration and performs tests on the system and its components, including drives if they are connected to Smart Array controllers. This utility is available on the HP website (http://www.hp.com/servers/diags). • POST messages Smart Array controllers produce diagnostic error messages (POST messages) at reboot. Many POST messages suggest corrective actions.
Drive procedures Identifying the status of a drive Identifying the status of a legacy drive Identify a legacy drive by its carrier, shown in the following illustration. When a drive is configured as a part of an array and connected to a powered-up controller, the drive LEDs indicate the condition of the drive.
Online/activity LED (green) Fault/UID LED (amber/blue) Interpretation Flashing regularly (1 Hz) Amber, flashing regularly (1 Hz) Do not remove the drive. Removing a drive may terminate the current operation and cause data loss. The drive is part of an array that is undergoing capacity expansion or stripe migration, but a predictive failure alert has been received for this drive. To minimize the risk of data loss, do not replace the drive until the expansion or migration is complete.
Item LED Status Definition 4 Drive status Solid green The drive is a member of one or more logical drives. Flashing green The drive is rebuilding or performing a RAID migration, strip size migration, capacity expansion, or logical drive extension, or is erasing. Flashing amber/green The drive is a member of one or more logical drives and predicts the drive will fail. Flashing amber The drive is not configured and predicts the drive will fail. Solid amber The drive has failed.
Recognizing drive failure (HP SmartDrive) If any of the following occurs, the drive has failed: • The drive status LED illuminates amber. • When failed drives are located inside the server or storage system and the drive LEDs are not visible, the Health LED on the front of the server or server blade illuminates. This LED also illuminates when other problems occur such as when a fan fails, a redundant power supply fails, or the system overheats.
Compromised fault tolerance CAUTION: When fault tolerance is compromised, data loss can occur. However, it may be possible to recover the data. For more information, see "Recovering from compromised fault tolerance (on page 25)." If more drives fail than the fault-tolerance method can manage, fault tolerance is compromised, and the logical drive fails. If this failure occurs, the operating system rejects all requests and indicates unrecoverable errors.
Before replacing drives • Open Systems Insight Manager, and inspect the Error Counter window for each physical drive in the same array to confirm that no other drives have any errors. For more information about Systems Insight Manager, see the documentation on the Insight Management DVD or on the HP website (http://www8.hp.com/us/en/products/server-software/product-detail.html?oid=489496#!tab=feat ures ). • Be sure that the array has a current, valid backup.
• Failure of a second drive in a RAID 6 configuration Time required for a rebuild The time required for a rebuild varies, depending on several factors: • The priority that the rebuild is given over normal I/O operations (you can change the priority setting by using HP SSA) • The amount of I/O activity during the rebuild operation • The average bandwidth capability (MBps) of the drives • The availability of drive cache • The brand, model, and age of the drives • The amount of unused capacity on
2. Restore data from backup. Writing data to the location of the unreadable sector often eliminates the error. 3. Remove and reinsert the replacement drive. This action restarts the rebuild process. If the rebuild process still terminates abnormally: 1. Delete and recreate the logical drive. 2. Restore data from backup. Case 2: The replacement drive has failed. Verify that the replacement drive is of the correct capacity and is a supported model.
When data rebuild on the new drive is complete, the Drive status LED changes from flashing green to solid green. 3. Repeat the previous step for the other drives in the array, one at a time. When you have replaced all drives, you can use the extra capacity to either create new logical drives or extend existing logical drives. For more information, see the HP Smart Storage Administrator User Guide on the HP website (http://www.hp.com/go/smartstorage/docs).
o 6. If a 1724 or 1727 POST message appears, drive positions were changed successfully and the configuration was updated. Continue with step 7. If the array did not configure properly, do the following: a. Power down the system immediately to prevent data loss. b. Return the drives to their original locations. c. 7. Restore the data from backup, if necessary. Verify the new drive configuration by running HP SSA ("Configuring an array" on page 18).
When the expansion process has finished, you can use the liberated storage capacity on the enlarged array to create new logical drives. Alternatively, you can use HP SSA to enlarge (extend) one of the original logical drives.
Electrostatic discharge Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers.
