4. Plug the other end of the battery cable into the connector on the cache module. 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. Unplug the cable from the battery pack. 5. Remove the battery pack from the server. 6. Plug the cable into the new battery pack. 7. Install the new battery pack into the server. 8. Verify that the other end of the cable is properly seated in the cache connector. NOTE: After installing a battery pack, you might see a POST message during reboot indicating that the array accelerator (cache) is temporarily disabled. This is normal, because the new battery pack is likely to have a low charge.
o If the LED is not lit, disconnect the battery cable from the cache. 4. Remove the controller from the server and place it on a firm, flat, nonconductive surface. 5. Remove the existing cache from the controller by pulling at both ends of the cache module with equal force. 6. Install the new cache on the controller. Press firmly above each connector to ensure good electrical contact. (If the cache is not properly connected, the controller cannot boot.) 7. Replace the controller in the server. 8.
Replacing, moving, or adding hard drives In this section Identifying the status of a hard drive ......................................................................................................... 20 Recognizing hard drive failure................................................................................................................. 21 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.................................................................................................................. 28 Battery pack LEDs................................................................................................................................... 29 Diagnostic tools .....................................................................................................................................
LED ID Color LED name and interpretation 8 Green CR7: Idle Task LED. This LED, together with LED 7, indicates the amount of controller CPU activity. For details, see the following table. Controller CPU activity level LED 7 status LED 8 status 0–25% Off Flashing 25–50% Flashing Off 50–75% On steadily Off 75–100% On steadily On steadily Battery pack LEDs Item ID Color Description 1 Green System Power 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.
Smart Array controllers produce diagnostic error messages (POST messages) at reboot. Many POST messages are self-explanatory and suggest corrective actions. For more information about POST messages, see the HP Servers Troubleshooting Guide. • 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 hard drives if they are connected to Smart Array controllers).
