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 or adding a battery ................................................................................................................. 18 Replacing the cache module or controller.................................................................................................. 22 Replacing or adding a battery CAUTION: Electrostatic discharge can damage electronic components. Be sure you are properly grounded before beginning this procedure.
6. While holding the battery assembly, tilt the clip until it is at about 30 degrees to the batteries, and then push the clip in line with the clip hinges until the clip detaches from the batteries. The rest of the procedure depends on whether you are replacing a battery or adding one. 7. • If you are replacing a battery, continue with the next step. • If you are only adding an optional third battery, go to step 9. Separate the batteries. a. Turn the batteries over. b.
9. Position the new battery and the remaining good battery as indicated, and then push them together and slide them until they are aligned. The batteries combine into one unit. 10. Install the battery clip. a. Position the clip so that the hinges on the clip are next to the appropriate hinge pillars on the batteries. b. Hold the clip at about 30 degrees to the batteries. c. Push the clip at the hinges until the clip clicks into place. 11. Reinstall the batteries. a.
b. Position the batteries so that the pegs A on the underside of each battery are in the appropriate holes B on the controller board and pegs C are in slots D. c. Slide the batteries toward the board bracket until they are firmly seated against the connectors on the cache module. 12. Secure the battery clip to the controller board: a. Swivel the clip over the cache module (1).
b. Push the clip firmly at both ends (2) until it clicks into place under the controller board. 13. Reinstall the controller in the server. After installing a battery pack, you might see a POST message during reboot indicating that the array accelerator (cache) is temporarily disabled. This behavior is normal because the new battery pack is likely to have a low charge. You do not need to take any action because the recharge process begins automatically when the battery pack is installed.
4. Pull the flanges on the battery clip outward (1), and then swivel the clip 180 degrees so that it rests on the batteries (2). 5. Swivel the latches on the DIMM connector outward (1). 6. Slide the battery assembly and the cache module off the controller board (2). The procedure at this point depends on whether you are replacing the controller or the cache module. 7. • If you are replacing the controller, go directly to the next step.
b. Position the batteries so that the pegs A on the underside of each battery are in the appropriate holes B on the controller board and pegs C are in slots D. c. Slide the batteries toward the board bracket until the connectors on the cache module are firmly seated in the DIMM connector. (When the cache module is correctly seated, the gold contacts on the cache module are completely hidden within the DIMM connector.) 8. Secure the battery clip to the controller board. a.
b. Push the clip firmly at both ends (2) until it clicks into place under the controller board. 9. Reinstall the controller in the server.
Replacing, moving, or adding hard drives In this section Identifying the status of a hard drive ......................................................................................................... 26 Recognizing hard drive failure................................................................................................................. 27 Replacing hard drives .............................................................................................................................
Online/activity LED Fault/UID LED (green) (amber/blue) Interpretation Flashing regularly (1 Hz) Do not remove the drive. Removing a drive may terminate the current operation and cause data loss. Amber, flashing regularly (1 Hz) 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 might be using 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.
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. If another drive in the array fails while fault tolerance is unavailable during rebuild, a fatal system error can 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.
1. Back up as much data as possible from the logical drive. CAUTION: Do not remove the drive that has the media error. Doing so causes the logical drive to fail. 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.
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 about these procedures, refer to the HP Array Configuration Utility User Guide. Moving drives and arrays You can move drives to other ID positions on the same array controller.
physical drives in the array. During this procedure, the logical drives each keep the same fault-tolerance method in the enlarged array that they had in the smaller array. 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.................................................................................................................. 34 Battery pack LEDs................................................................................................................................... 35 Diagnostic tools .....................................................................................................................................
LED ID Color LED name and interpretation 7 Green CR506: Command Outstanding LED. The controller is working on a command from the host driver. 8 Green CR505: Controller Heartbeat LED. This LED flashes every 2 seconds to indicate the controller health. 9 Green CR504: Gas Pedal LED. This LED, together with item 10, indicates the amount of controller CPU activity. For details, see the following table. 10 Green CR503: Idle Task LED.
LED3 pattern LED4 pattern Interpretation — One blink every two seconds The system is powered down, and the cache contains data that has not yet been written to the drives. Restore system power as soon as possible to prevent data loss. Data preservation time is extended any time that 3.3 V auxiliary power is available, as indicated by LED 2. In the absence of auxiliary power, battery power alone preserves the data. A fullycharged battery can normally preserve data for at least two days.
