To install the controller: 1. Power down the server. 2.
3. When you have finished installing the operating system as directed during the Express Setup procedure, remove the operating system CD and insert the Smart Setup media. 4. Install the Integrity Support Pack ("Installing device drivers and Management Agents" on page 17). Controller installation is complete.
Installing the controller hardware In this section Before beginning the installation .............................................................................................................. 10 Preparing the server ............................................................................................................................... 10 Installing the controller board ..................................................................................................................
1. Remove or open the access panel. 2. Select an available 3.3-V PCI or PCI-X slot. 3. If the controller is being hot-plugged, power down the slot. 4. Remove the slot cover or open the hot-plug latch. Save the retaining screw if one is present. 5. Slide the controller board along the slot alignment guide, and press the board firmly into the slot so that the contacts on the board edge are properly seated in the system board connector. 6.
4. For each SCSI bus, manually set the SCSI ID on each drive to a unique value in the range of 0 to 15, except 7 (which is reserved for controller use). For detailed instructions, consult the documentation that is provided with the drive. 5. Attach a multi-device SCSI cable from the internal connector of the controller to the non-hotpluggable hard drives. (The cable might have been provided with the server.) 6. Replace the access panel, and secure it with the thumbscrews if any are present.
Updating the firmware In this section Methods for updating the firmware (Windows® or Linux®)......................................................................... 13 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 Introduction ........................................................................................................................................... 14 Comparing the utilities ............................................................................................................................ 14 Using ORCA.......................................................................................................................................... 15 Using ACU .....
Supported features ACU ORCA Suitable for configuration while offline -- + Supported procedures ACU ORCA Creation and deletion of arrays and logical drives + + Assignment of RAID level + + Sharing of spare drives among several arrays + -- Assignment of multiple spare drives per array + -- Setting of stripe size + -- Migration of RAID level or stripe size + -- Configuration of controller settings + -- Expansion of an array + -- Creation of multiple logical drives per array +
5. Press the Enter key to continue. You can now create another logical drive by repeating the previous steps. NOTE: Newly created logical drives are invisible to the operating system. To make the new logical drives available for data storage, format them using the instructions given in the operating system documentation. Using ACU For detailed information about using ACU, refer to the HP Array Configuration Utility User Guide.

3. Power up the system. As Linux boots, it recognizes the controller. 4. Enter one of the following commands as appropriate to ensure that the driver is loaded correctly: Red Hat: #mkinitrd -f /boot/efi/efi/redhat/initrd-$(uname -r).img $(uname -r) Novell (SLES): #mkinitrd -k /boot/vmlinux -i/boot/initr 5. For Novell, enter the following command to confirm that the driver is active: #lsmod | grep cciss If the driver is active, the system responds by displaying cciss.
Upgrading or replacing controller options In this section Replacing a battery ................................................................................................................................ 19 Replacing the expansion module.............................................................................................................. 20 Replacing a battery WARNING: There is a risk of explosion, fire, or personal injury if the battery pack is not properly handled.
b. Lift the battery pack off the cache board (2). 4. Remove the secondary cache battery pack: a. Unhook the wire retainer that holds the battery pack to the controller board (1). b. While holding the battery in one hand, pull the plastic retainer tabs up and push them through to the other side of the controller board (2). 5. Replace whichever battery is degraded. 6. Reinstall the batteries on the cache board and the controller board. 7. Reinstall the cache board and its battery on the controller.
2. Press firmly on the back of the expansion module to seat the expansion module connector securely in the socket on the controller board (3). 3. Secure the expansion module to the controller board by inserting and tightening the appropriate screw (provided in the kit) in the back of the controller board (4). To remove the expansion module, reverse this procedure.
Replacing, moving, or adding hard drives In this section Identifying the status of a hard drive ......................................................................................................... 22 Recognizing hard drive failure ................................................................................................................. 23 Replacing hard drives .............................................................................................................................
Activity LED (1) Online LED Fault LED (2) (3) Interpretation On or flashing Flashing Do not remove the drive. Removing a drive may terminate the current operation and cause data loss. Off The drive is rebuilding or undergoing capacity expansion. On Off Off Do not remove the drive. The drive is being accessed, but (1) it is not configured as part of an array; (2) it is a replacement drive and rebuild has not yet started; or (3) it is spinning up during the POST sequence.
• 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. • RAID 1+0 configurations can tolerate multiple drive failures as long as no failed drives are mirrored to one another. • RAID 5 configurations can tolerate one drive failure. • RAID ADG configurations can tolerate simultaneous failure of two drives.
automatically (as indicated by the blinking Online LED on the replacement drive) if the array is in a faulttolerant configuration. If you replace a drive belonging to a fault-tolerant configuration while the system power is off, a POST message is displayed when the system is next powered up. This message prompts you to press the F1 key to start automatic data recovery.
If another drive in the array fails while fault tolerance is unavailable during rebuild, a fatal system error may occur, and all data on the array is then lost. In exceptional cases, however, failure of another drive need not lead to a fatal system error.
2. Replace any drive. The data on the new drive is recreated from redundant information on the remaining drives. CAUTION: Do not replace any other drive until data rebuild on this drive is complete. 3. When data on the new drive has been rebuilt (the Activity LED turns off), 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.
c. Open ACU and navigate to the controller that contained the RAID ADG volume. ACU displays the missing RAID ADG volume using a different icon to indicate that the volume is unavailable. d. Delete the RAID ADG volume. e. Accept the configuration change, and then close ACU. f. Power down the system. 4. Move the drives. 5. Power up the system. If a 1724 POST message is displayed, drive positions were changed successfully and the configuration was updated.
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 enlarge one of the original logical drives. This latter process is called logical drive capacity extension and is also carried out using ACU.
Diagnosing array problems In this section Controller board runtime LEDs.................................................................................................................. 30 Cache module LEDs................................................................................................................................ 31 Diagnostic tools .....................................................................................................................................
LED ID Color LED name and interpretation 8 Amber CR11: Battery Status LED. For interpretation, refer to Cache module LEDs (on page 31). 9 Green CR10: Battery Charging LED. For interpretation, refer to Cache module LEDs (on page 31).
Item 1 (amber LED) Item 2 (green LED) Slow blink (once every 16 seconds) Interpretation This display pattern might occur after the system is powered down. It indicates that the cache contains data that has not yet been written to the drives. Restore system power as soon as possible to prevent data loss. (The battery lifetime depends on the cache module size. For further information, refer to the controller QuickSpecs on the HP website (http://www.hp.com).
