Overview of the installation procedure In this section Quick installation procedure (Windows or Linux) ......................................................................................... 7 Quick installation procedure (Windows or Linux) Before installing the controller, refer to the support matrix on the HP website (http://www.hp.com/products1/serverconnectivity) to confirm that the server and operating system support the controller. To install the controller: 1. Power down the server. 2.
Controller installation is complete. The latest firmware, drivers, utilities, software, and documentation for HP Integrity servers are available on the support page of the HP website (http://www.hp.com/support/itaniumservers).
Installing the controller hardware In this section Preparing the server ................................................................................................................................. 9 Installing the controller board .................................................................................................................... 9 Connecting storage devices.....................................................................................................................
6. Connect storage devices to the controller. (For details of the procedure, see "Connecting storage devices (on page 10).") 7. Close or replace the access panel, and secure it with thumbscrews, if any are present. CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage. Connecting storage devices 1. Power down the server. 2.
Updating the firmware In this section Methods for updating the firmware (Windows® or Linux®)......................................................................... 11 Methods for updating the firmware (Windows® or Linux®) To update the firmware on the server, controller, or hard drives, use Smart Components. The most recent version of a particular component is available on the support page of the HP website (http://www.hp.com/support). Some components are also available on the Smart Setup media. 1.
Configuring an array In this section Utilities available for configuring an array................................................................................................. 12 Using ORCA.......................................................................................................................................... 12 Using ACU or ACU-CLI ...........................................................................................................................
The ORCA main menu appears, enabling you to create, view, or delete a logical drive. To create a logical drive using ORCA: 1. Select Create Logical Drive. The screen displays a list of all available (unconfigured) physical drives and the valid RAID options for the system. 2. Use the Arrow keys, Spacebar, and Tab key to navigate around the screen and set up the logical drive, including an online spare drive if one is required.
Installing device drivers and Management Agents In this section Systems using Microsoft® Windows® ...................................................................................................... 14 Systems using Linux®..............................................................................................................................
1. Follow the standard controller installation procedure. 2. Reboot the server. 3. Follow the standard procedure for installing Linux. As Linux is installed, it recognizes the controller and automatically loads the correct driver. In a system that already has Linux installed: 1. Power down the system. 2. Follow the standard controller installation procedure. 3. Power up the system. As Linux boots, it recognizes the controller. 4.
Upgrading or replacing controller options In this section Replacing the cache ............................................................................................................................... 16 Replacing the cache CAUTION: Do not use this controller with cache modules designed for other controller models, or the controller will malfunction and you could lose data. Also, do not transfer this cache module to a different controller module, or you could again lose data. 1.
Replacing, moving, or adding hard drives In this section Identifying the status of a hard drive ......................................................................................................... 17 Recognizing hard drive failure................................................................................................................. 18 Replacing hard drives .............................................................................................................................
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.
Effects of a hard drive failure When a hard drive fails, all logical drives that are in the same array are affected. Each logical drive in an array can use a different fault-tolerance method, so each logical drive can be affected differently. • RAID 0 configurations cannot tolerate drive failure. If any physical drive in the array fails, all nonfault-tolerant (RAID 0) logical drives in the same array will also fail.
Replacing hard drives The most common reason for replacing a hard drive is that it has failed. However, another reason is to gradually increase the storage capacity of the entire system. If you insert a hot-pluggable drive into a drive bay while the system power is on, all disk activity in the array pauses for a second or two while the new drive is spinning up.
Automatic data recovery (rebuild) When you replace a hard drive in an array, the controller uses the fault-tolerance information on the remaining drives in the array to reconstruct the missing data (the data that was originally on the replaced drive) and write it to the replacement drive. This process is called automatic data recovery, or rebuild. If fault tolerance is compromised, this data cannot be reconstructed and is likely to be permanently lost. Fault tolerance is unavailable during a rebuild.
Observation Cause of rebuild termination None of the drives in the array have an illuminated amber Fault LED. One of the drives in the array has experienced an uncorrectable read error. The replacement drive has an illuminated amber Fault LED. The replacement drive has failed. One of the other drives in the array has an illuminated amber Fault LED. The drive with the illuminated Fault LED has now failed. Each of these situations requires a different remedial action.
Upgrading hard drive capacity You can increase the storage capacity on a system even if there are no available drive bays by swapping drives one at a time for higher capacity drives. This method is viable as long as a fault-tolerance method is running. CAUTION: Because it can take up to 30 seconds per gigabyte to rebuild the data in the new configuration, the system could be unprotected against drive failure for many hours while the drives are upgraded.
4. Power up the system. If a 1724 POST message appears, drive positions were changed successfully and the configuration was updated. If a 1785 (Not Configured) POST message appears: a. Power down the system immediately to prevent data loss. b. Return the drives to their original locations. c. 5. Restore the data from backup, if necessary. Verify the new drive configuration by running ORCA or ACU ("Configuring an array" on page 12).
Diagnosing array problems In this section Controller board runtime LEDs.................................................................................................................. 25 Diagnostic tools .....................................................................................................................................
